Step 4 Connect Load and Line Voltage to Relays
Before making any connections to the relays, make sure that none of the load circuits are shorted. Route conductors from the circuit
breaker through each relay's SPST output terminals, and from there to the loads. Confirm that each circuit is wired to the relay specified
in the electrical construction drawings and relay schedule forms provided with the panel.

Step 5 Power Up and Test Relays
1. Apply power to the LMCP power supply ONLY. Do NOT apply power to the controlled circuit loads.
2. Locate the relay control buttons on the Relay Driver card next to each relay's 5-wire plug-in termination. Press the relay control
button to toggle it ON/OFF. The relay clicks, the relay's mechanical override switch moves and the LED status indicator changes.
3. Confirm the operation by measuring the continuity at the line voltage terminations of each relay.
4. Apply power to the relays.
5. Being careful not to touch any line voltage wiring, toggle each relay ON/OFF again and confirm that each relay controls the
appropriate load.
The last page of this guide includes a form for documenting the relays.
