1 Installation Instructions 1394 External Shunt Resistor Kit (Catalog Number 1394-SR10A) Introduction This publication provides the information necessary to install the 1394 External Shunt Resistor kit on a 5 or 10 kw 1394 system. The 1394-SR10A External Shunt Resistor provides a way of dissipating regenerative energy that exceeds the capacity of the internal shunt resistor provided with every 5 and 10 kw system module. Shunt Resistor kits mounted outside your 1394 system cabinet can require additional guarding or other enclosures to meet local codes. Important: The 1394-SR10A Shunt Resistor kit should only be used with 5 and 10 kw 1394 systems. If you are using a 22 kw 1394 system, refer to the 1394 Digital AC Multi- Axis Motion Control System User Manual (publication ) for information on the 1394-SRxAx Shunt Modules. This Kit Contains Use the table below to verify that you have received the following: Part: Quantity: 16 ohm shunt resistor assembly 1 Fuse block 1 Fuse 1 Jumper block 1 Shunt Ratings The table below contains the ratings for the internal 5 and 10 kw 1394 system shunt resistor and the external 1394-SR10A shunt resistor kit.

2 External Shunt Resistor Kit Dimensions The dimensions of the 1394-SR10A shunt resistor assembly and fuse block are shown in the figure below. Figure SR10A Shunt Resistor Assembly External Shunt Resistor Dimensions are in millimeters and (inches) Depth = 100 (3.94) Fuse Holder Dimensions are in millimeters and (inches) (6.5) Wire length = 203 (8.0) 19.1 (0.75) 9.6 (0.38) 38.1 (1.50) Wire length = 1524 (60.0) 380 (14.96) 342 (13.46) Wire length = 203 (8.0) 82.6 (3.25) ( / ) 36.5 (1.48) 17 (0.67) 82.5 (3.25) Fuse holder 38.1 (1.50) Wire length = 1524 (60.0)! ATTENTION: These resistors can reach temperatures in excess of 350 C (662 F). Appropriate guarding must be provided to avoid the hazard of shock or burn and ignition of flammable material. Install per local codes. Mounting Your External Shunt Resistor To mount your 1394-SR10A Shunt Resistor: 1. Remove all 24V control power, contactor enable power, and 360/ 480V AC input power from the system.! ATTENTION: To avoid the hazard of electrical shock or injury, verify that all power has been disconnected before continuing. 2. Wait at least two minutes for the DC Link to discharge.! ATTENTION: The 1394 contains stored energy devices. To avoid the hazard of electrical shock or injury, verify that the bus voltage is zero before continuing.

Using two M10 (3/8 in.) bolts, mount the shunt resistor assembly vertically on a flat rigid metal surface that will not be subjected to shock, vibration, moisture, oil mist, dust or corrosive vapors. Note: To extend the leadwire length up to 15 m (49 ft total overall length), use MTW, 105 C (302 F), Class H insulated wire (UL styles 3349, 3374, or equivalent). Wiring Your External Shunt Resistor To wire your 1394-SR10A shunt resistor: 1. Verify that all power is removed from the system as described in Mounting Your External Shunt Resistor above. 2. If your system module is: Series A and B Series C Do this: Go to Wiring Your External Shunt Resistor (Series A and B). Go to Wiring Your External Shunt Resistor (Series C). Wiring Your External Shunt Resistor (Series A and B) 1. Open the front door of the 1394 system module. 2. Remove and discard the COL/INT jumper wire from the power terminal block in the lower right corner, as shown in Figure 2. Figure System Module Jumper Removal (Series A and B) Jumper

Figure System Module Jumper Installation (Series A and B) Jumper block to P1 4. Install and tighten the resistor wire with the fuse in the DC+ terminal on the power terminal block in the lower right corner. 5. Install and tighten the other resistor wire in the COL terminal on the power terminal block in the lower right corner. 6. Re-apply power and resume operation. Refer to the 1394 Digital, AC, Multi-Axis Motion Control System User Manual (publication ) for startup information. Important: Use fuse replacement kit (1394-SR10A-FUSE-A) when replacing the 1394-SR10A shunt fuse. Refer to the 1394 Digital, AC, Multi-Axis Motion Control System User Manual (publication ) for additional information regarding fuse replacement kits.

Remove and discard the jumper wire between J11-1 and J11-2, as shown in Figure 4. Figure System Module Jumper Removal (Series C) Remove jumper J bottom view 3. Install the shunt resistor wire leading to the fuse in connector J Install the other shunt resistor wire in connector J Tighten the J11 connector screws (torque value = N-m, lb-in.). 6. Re-apply power and resume operation. Refer to the 1394 Digital, AC, Multi-Axis Motion Control System User Manual (publication ) for startup information. Important: Use fuse replacement kit (1394-SR10A-FUSE-A) when replacing the 1394-SR10A shunt fuse. Refer to the 1394 Digital, AC, Multi-Axis Motion Control System User Manual (publication ) for additional information regarding fuse replacement kits.
