Input Power Connectors - ADC PowerWorx Select Series User Manual

CONNECT USING CRIMP-ON SPADE LUGS OR RING CONNECTORS THAT HAVE A MAXIMUM WIDTH OF 0.325 IN.
(8.255 MM) ON #12 TO #22 AWG WIRE OR USING #12 TO #22 AWG WIRE WITH INSULATION STRIPPED BACK.
TORQUE THE SCREWS TO APPROXIMATELY 9 POUND-FORCE INCHES (1 NEWTON METER).

4.10 Input Power Connectors

Connect input power wires to the input power connectors labeled "BATT" and connect return
wires to the return connectors labeled "RTN" for both buses in the circuit breaker panel as
shown in Figure
applicable local electrical codes and/or National Electrical Codes.
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.
Caution: Connect only the input voltage wire (labeled BATTERY, BATT, NEGATIVE,
NEG, or – and/or the voltage value) to the connector on the circuit breaker panel labeled BATT
(battery). Connect only the input return wire (labeled RTN, RETURN, POSITIVE, POS, +, or
BATTERY GROUND) to the connector on the circuit breaker panel labeled RTN (return).
Caution: Caution should be taken to not reverse input wires to the circuit breaker panel. In the
circuit breaker panel, the internal battery (negative voltage) wiring is protected and the internal
return wiring is not protected by circuit breakers or fuses.
Use the included 2-hole lugs with #2 AWG copper wire (insulation stripped back) or optional 2-
hole lugs available as accessories (see
wire. Tighten the nuts to approximately 16 pound-inches (1.8 Newton meters) of torque.
Replace the protective cover on the circuit breaker panel after all the wiring connections are
made and before power is applied to the panel (refer to
Installation/Removal).
