9 Chapter 1 Product Introduction 1.3 Safety Precautions Installation Notes 1_ Install the power meter according to instructions on the manual. Use appropriate personal protective equipment (PPE) and follow safe electrical work practices. Only qualified electrical workers should install this equipment. Such work should be performed only after reading the entire set of installation instructions. Operate the power meter according to instructions on the manual. Neglecting fundamental installation requirements may lead to personal injury as well as damage to electrical equipment or other property. This equipment should be installed in a suitable insulated and fireproof enclosure. Operation Notes DO NOT work alone. Before performing visual inspections, tests, or maintenance on this equipment, disconnect all electric power sources. Always use a properly rated sensing device to confirm that power is off. Replace all devices, doors and covers before turning on power to this equipment. Carefully inspect the work area for tools and objects that may have been left inside the equipment. Operation Notes Never short the secondary of a Power Transformer (PT). Never open circuit a Current Transformer (CT) Ensure that the CT secondary winding is fixed securely on the equipment. It may damage the equipment if the secondary winding becomes loose during operation. When used with CTs, make sure the CTs are UL2808 listed in America and Canada and meet or exceed the accuracy specifications for IEC class or accepted by authority having jurisdiction (AHJ) in other areas. Wiring Notes When the measured current is higher than the rated specification for the device, consider using an external current transformer (CT). When the measured is higher than the rated specification for the device, consider using an external potential transformer (PT) (line : 35 to 690V AC L-L or phase : 20 to 400V AC L-N). Connect only one cord to one plug on the quick connector. For the device is accidently unplugged, check the connecting cord and restart. Maintenance and Inspection Notes While cleaning the equipment, be sure to unplug all external power sources first. Use a dry cloth to clean the equipment s exterior. DO NOT open the equipment or touch the wiring inside to prevent personal injury as well as damage to electrical equipment or other property. DO NOT use aerosol sprays, solvents, or abrasives. 1-3

20 DPM-C501L Operation Manual 3.2 Basic Checks _3 Items General Check Pre-operation Check (not supplied with power) Pre-running Check (supplied with power) Contents Regularly check for mounting looseness where the power meter and device are connected. Prevent foreign objects, such as oil, water, or metal powder entering the device through the ventilation holes. Prevent drill shavings or other debris entering the power meter. If the power meter is installed at a location with harmful gas or dust, prevent those materials from entering the power meter. Insulate the connections at the wiring terminals. Communications wiring should be done properly to prevent abnormal operations. Check for the presence of conducive and flammable objects, such as screws or metal pieces in the power meter. If electronic devices near to the power meter experience electromagnetic interference, take steps to reduce the electromagnetic interference. Check for the correct level for the power supplied to the power meter. Check if the power indicator light is lit. Check if communication between every device is normal. If there is any abnormal response from the power meter, contact your distributor or our customer service center. 3.3 Wiring Wiring Diagrams To avoid electric shock, do not change the wiring when the power is on. Install a breaker switch on the power cord for the meter because there is no power switch on the power meter. When the measured is higher than the rated specification for the device, it is necessary to use an external potential transformer (PT). When the measured current is higher than the rated specification for the device, it is necessary to use an external current transformer (CT).
