1. Make sure that power is disconnected at the circuit breaker before proceeding.
2. Prepare the power and safety grounding wires using the appropriate size wire, crimp on ring lugs and heat shrink tube for all
three wires. Due to the limited space for the safety ground wire, we recommend using a 90 angled lug such as:
• TE Connectivity Solistrand "16-14HD 90 Ring 8", part number 184269-1 for 14 AWG wire
• PIDG 12-10 Ring #8, 90-DEG, part number 1958340-1 for 12 or 10 AWG wire
