To install the ACI KW320-P1-D-W-RC-PC Power Meter, follow these steps:
1. Ensure that the meter is installed in an appropriate environment. The polycarbonate, NEMA 4X panel enclosure provides protection against dust and moisture. If installing the meter outdoors, use NEMA 4X-rated grommets or conduit to maintain the NEMA 4X rating.
2. Open the swing panel of the enclosure to access the terminal strip inside. The incoming power should be brought into the enclosure through the pre-cut holes located at the bottom of the enclosure and landed on the line side of the terminals.
3. Connect the voltage inputs to the L1, L2, and L3 terminals. If applicable, connect the neutral to the N terminal. Lift the terminal covers to access the screws and tighten the conductors into the terminals.
4. Connect the current transformers (CTs) around a bus bar or other conductor to measure the current. Pay attention to the polarity of the CTs during installation. Route the CT leads into the enclosure through the pre-cut holes and connect them to the positive and negative CT terminals labeled CT1+, CT1-, and so on. The positive lead should be connected to the CT terminal marked (+), and the negative lead should be connected to the CT terminal marked (-).
5. Before setting up the meter's wiring, connect the meter's ground terminal to the switch gear's ground terminal.
