8 Instruction Manual Mounting Note: Use extreme care in handling the recloser so that no force is exerted on the side terminals or on the individual poles as damage may result. Attach the mounting bracket to the pole or structure using a 3 4" lag or thru bolt (customer supplied). Hoist the MVR by creating a sling around the main body and the side terminal on the recloser, and lower it into the mounting bracket. Orient as desired and then lock in place by torquing the two 3 8"-16 set screws to 20 ft.-lbs. The singlephase recloser can be oriented from 0 to 180 degrees as shown at right. Hoist the MVR by creating a sling that uses the lifting rings provided on the recloser. Mount the recloser on the pole or structure using two 3 4" lag or thru bolts (customer supplied) as specified on the product drawings shown on and 19. With the SEL 351R or 351R Falcon control, mount the power module onto the pole below the recloser, as shown at right. With the SEL 651R control, no power module is needed and the 32-pin cable should be plugged directly into the recloser. CAUTION: Follow approved safety practices when lifting and mounting the MVR. Use lifting rings on three-phase units and lift smoothly, limiting shifting to avoid damage. Do not lift three-phase MVRs by the side terminals as damage could result. High-Voltage Terminations The terminal connectors supplied with each recloser are aluminum alloy with standard NEMA two-hole drilling and the bolts/nuts are silicon bronze. The electrical connection at the terminal pad must be treated with Alcoa No. 2 joint compound or equivalent. Each terminal should be wire brushed through the compound to improve the connection. If the terminal pad is rotated, the connector bolt(s) must be loosened before turning the pad. Retighten the bolt(s) to 25 ft.-lbs. after repositioning. CAUTION: Rotating the terminal connector without properly loosening the connector will apply excessive force on the terminal stud and could damage the interrupter assembly.

Instruction Manual Grounding To ensure the maximum amount of protection for internal control components during possible power surge events, the recloser and control cabinet need to be solidly grounded together. The recloser ground conductor must be connected to the supplied #10 2 AWG ground lug located on the recloser s frame base. All separate grounds should be connected to the main ground wire. All connections to the SEL control (including the control cable, which contains a ground) must be routed in close proximity to and parallel to the main ground paths and should be approximately equal in length. When using a power module with a 351R or 351R Falcon, the power module box must also be grounded. See Set-Up on for a visual representation. Electronic Operation Test Using the controller, open and close the MVR electrically by pressing the marked open and close buttons. Confirm that the selected button is in agreement with the position indicator on the control panel as well as the recloser position indicator. The recloser position indicator is located on the bottom of the recloser as shown below. MVRs are designed to operate with a total circuit resistance of 6.5 7.3 ohms across the TRIP/CLOSE pins on the SEL control interface. Open Position Closed Position WARNING: Hazardous voltage. Recloser and control must be solidly grounded. Improper grounding can result in contact with high voltage, which will cause severe personal injury or death and equipment damage. Disconnecting the control cable when the recloser is energized could result in high voltage on the pins if the recloser tank is not grounded as specified. Closed Position Individual Pole Position Indicator (Side View) Open Position Individual Pole Position Indicator (Bottom View) Voltage Sensor Set-Up All Elastimold MVRs come with pre-calibrated, loadside capacitive voltage sensors that are capable of measuring amplitude and phase angle with an accuracy of approximately 3% under normal operating conditions (-10 C to 45 C) and +/-5% at extreme conditions (-40 C to 65 C). For 3-phase MVRs, optional pre-calibrated line-side resistive voltage sensors are also available and are capable of measuring the voltage with a higher accuracy of approximately 1%. All sensors require an 8VAC LEA voltage sensor input on the SEL 651Rx2 control. Refer to the Elastimold Source Side Voltage Sensor (ESSVS) Installation Instructions for mounting details. The ESSVS are not used with the SEL 351R, 351R Falcon or 351RS Kestrel Controls. CAUTION: Do not energize the recloser for service until all control settings have been properly programmed and verified. Refer to the appropriate SEL control manual for programming procedures. Failure to comply may result in control and recloser misoperation. WARNING: Hazardous voltage. Do not rely on the contact position indicator to determine that the line has been de-energized. Always establish a visible disconnect and establish grounds when performing de-energized line work. Failure to follow proper safety practices can result in contact with high voltage, which can cause death or severe personal injury. 10 SEL is a registered trademark of Schweitzer Engineering Laboratories, Inc.

Manual Trip Lever Test With the switch closed, pull down the yellow trip lever as shown in center photo at right and verify that the recloser opens. The position indicators located on the bottom of the recloser will be GREEN for OPEN. The manual trip lever will remain in the down position until returned to the up position. When in the down TRIPPED position, the manual trip will block all close operations until it is manually restored to the up NORMAL position. When using the standard SEL 651Rx2, the control standard settings will also send a signal to open when the manual trip handle is pulled. The recloser can be closed once the manual trip handle has been restored to the normal position by pressing the close button on the control. Vacuum Interrupter Tests Closed Position Manual Trip Lever Closed Position Every recloser is quality checked and tested before leaving the factory to assure it meets all design specifications. In order to verify proper operating condition after shipment and before installation, two tests should be performed to evaluate the vacuum contacts. These tests should be performed across each module separately and can be performed again, as desired, throughout the life of the recloser. Open Position WARNING: When testing at high voltage, the MVR and high-voltage test equipment should be in a test cage or similar protective area to prevent accidental contact with the high-voltage parts. All equipment needs to be solidly grounded. Failure to comply can result in death, severe personal injury and equipment damage. Loss of vacuum results in complete breakdown across open vacuum contacts at voltages below 30kV RMS. Only AC high potential testing is meaningful. With the recloser in the OPEN position, apply 30kV RMS across each individual contact for 15 seconds. To avoid possible generation of X-rays, do not apply more than 30kV RMS. During the high potential testing, self-extinguishing, momentary breakdowns lasting only a few seconds may occur. These breakdowns are not significant but can result in false indication of vacuum loss if the test set uses a high-speed overload relay or breaker. During normal operation with the recloser in service, loss of vacuum or a defective module may be indicated by excessive AM radio noise with the recloser open or by measuring a difference in surface temperatures (differential of more than 5º C temperature rise above normal ambient) between poles on the same recloser. When loss of vacuum occurs, contact resistance will typically increase. Test Equipment Load Contact Manual Trip Lever Open Position Line Contact With the recloser in the CLOSED position, measure the resistance across each module. Resistance values should be less than 200 micro-ohms. If higher resistance values are measured, contact your local Thomas & Betts representative.

Instruction Manual Operation The recloser receives the necessary signal to open and close from the control circuitry. For specific information concerning the operation of the control and how to change settings, please refer the appropriate SEL control manual. When using standard SEL settings files, the CT ratio will already be preset to 1000:1 and the voltage sensors will come pre-calibrated (used on the 651Rx2 only). If standard settings files are not used, the CT input in the SEL control will need to be adjusted to 1000:1. All voltage sensors require an 8VAC LEA input and are pre-calibrated to a ratio of 10kV on the line to 1VAC into the SEL control. For specific information on how to adjust settings and curves, please refer to the appropriate SEL control manual. Note that certain SEL controls limit the number of reclose sequences when AC or battery is not present. Please consult Schweitzer Engineering Laboratories. For specifications, please refer to the Power Module Box Installation and Operation Instructions. Maintenance CAUTION: The complete recloser system, including control, requires routine inspection and maintenance if damage is found to ensure proper operation. If it is not maintained, it may fail to operate properly. Improper operation may cause equipment damage and possible personal injury. The Elastimold MVR is designed to be maintenance free under normal operating conditions, and the EPDM/silicone insulation is not prone to the cracking or chipping that sometimes occurs with porcelain or epoxy insulators. However, should damage occur as a result of an external event, in most cases it is possible to replace the damaged components due to the modular design of the recloser. Both the top and bottom silicone shed, as well as the side terminal, can be removed and replaced if damaged by external arcing, a knife cut, etc. If damage extends to the main body of the pole, the pole in each phase can be replaced individually. If damage occurs, please contact Thomas & Betts customer service. If it becomes necessary to clean the main body or sheds, recommended cleaning agents are soap and warm water or isopropyl alcohol. CAUTION: All MVRs are sealed and leak tested prior to shipment to prevent moisture ingress. Do not open the lower cover as it is possible that the MVR will not reseal when the cover is closed. While the diaphragm will keep moisture from ever entering the high-voltage chamber, excessive moisture ingress could cause damage to the magnetic actuator mechanism and misoperation. CAUTION: Do not remove and replace the side terminal in the field. The MVR incorporates a unique diaphragm technology that fully encapsulates the high-voltage chamber in the MVR. The side terminal must be vented during installation and then sealed to prevent pressure build-up against the diaphragm during the installation process. Improper installation may cause equipment damage and possible personal injury.
