SOnly qualified service personnel (such as a licensed electrician) shall perform the electrical installation. Risk of electrical shock.

SAlways follow all personal protective equipment (PPE) and other safety rules when working around electricity.

C A U T I O N

SUse the branch circuit breakers to disconnect hazardous voltage from the EMS−UGK. Turn off the breaker before disconnecting the voltage measuring circuit cables, or hazardous voltage may be present at the exposed end of the cable.

STo prevent mechanical damage, coil and secure any excess cable away from the floor.

The EMS−UGK is designed for quick and easy installation. Labels on the harnesses describe where to connect the CTs and wire taps. Keyed circular connectors provide a quick and secure installation to the electronics module.

To connect the wiring for the EMS−UGK:

C A U T I O N

Before wiring the EMS−UGK, disconnect the load and shut down the host equipment. Refer to the user’s guide for the host equipment for shutdown instructions.

1.Verify that no circuits on which the EMS−UGK will be installed are energized. Be absolutely sure there is no power.

2.Optional. Connect the ground cable (not supplied) from the host equipment to the M5 ground bonding screw on the bottom of the electronics module. Figure 4 shows the location of the ground bonding screw.
