Installing the 5A CTs on the PowerLogic EM4805

Use the two 12-pair wiring harnesses provided with the meter to connect the 5A CTs to the PowerLogic EM4805.

For wire color coding, see Table 3 or the label inside the outer cover of the meter. Follow these instructions to install the 5A CTs on the PowerLogic EM4805.

Do not apply power until you have made these connections and followed all instructions below:

• Connect all CTs to shorting blocks to the appropriate circuits

• Connect the shorting blocks to the cables

• Connect the cables to the PowerLogic EM4805

DANGER

HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH

• Turn off all power supplying this equipment before working on or inside the equipment.

• Always use a properly rated voltage sensing device to confirm the power is off.

• NEVER open circuit a CT; use the shorting block to short circuit the leads of the CT before removing the connection from the meter.

• Do not crimp the insulation when making the wire connections.

Failure to follow these instructions will result in death or serious injury.

1. Connect the two wiring harnesses to the PowerLogic EM4805.

The connectors are labeled Plug 1/Plug 5 to Plug 4/Plug 8 on the cable. This is also labeled on the meter. Ensure the connectors are inserted in the proper order and that the connectors are securely locked in place.

a. Connect the first wiring harness to the Mate-n-LokTMconnectors 1 to 4, and secure the cables to the PowerLogic EM4805 chassis with cable ties.

b. Connect the second wiring harness to the Mate-n-LokTMconnectors 5 to 8, and secure the cables to the PowerLogic EM4805 chassis with cable ties.

2. Turn off the power feed to the panel where the CTs are being installed. Always use a properly rated voltage sensing device to confirm the power is off.

3. Route the free end of the cable out of the meter enclosure through the slot in the base of the chassis.

4. Strip the plastic sheaths to an appropriate length to expose the wire pairs. Cut and strip the wire pair leads to an appropriate length.

5. Connect the wire pair leads from the meter to the CT shorting block. See Table 3 for the color pair assignment of each meter point. Ensure that the CT shorting block is in the shorted position.

6. Connect the CT wire pair leads to the input of the CT shorting block. See Table 3 for the color pair assignment of each meter point.

7. Remove the feed wire from the circuit breaker, place the CT over the wire, and reconnect to the circuit breaker. Ensure that the arrow on the CT label is pointing in the direction of the energy flow (toward the load).

NOTE: The direction of the energy flow is indicated on the CT.
