4. Tighten the output power terminal block nuts to 12 pound-force inches (1.3 Newton-
meters) maximum of torque.
5. Route the free end of each output power cable to the equipment for connection.
4.11 Connecting Input
Input power is supplied to the circuit breaker panel through the A and B input power terminal
blocks located on the rear side of the panel. Each block consists of two pairs of 0.25-inch studs
that are used for connecting the negative (BATT) and positive (RTN) input power cables. The
stud pairs are mounted on 0.625 inch centers and accept 2-hole compression lugs. The
maximum lug width is 0.62 inches. Nuts with captive washers are provided to secure the
compression lugs to the terminal block. In selecting wire size, follow local code. Refer to
Appendix A for ampacity guideline.
Warning: Use of one bus only on a dual bus panel will result in false alarms for the unused bus.
Power is required on both buses on a dual bus panel for normal operation.
