4.8Output Power Connectors

Note: Before connecting the output or input power wires, measure the resistance of each bus input connector as specified in Subsection 5.2, Resistance Test.

Connect the output BATT and RTN terminals for each fuse circuit on each set of terminal strips as follows (see Figure 20):

Screw-down barrier terminal strip: Use #12 to #22 AWG wire. Wire leads should be equipped with crimp-on spade lugs or ring connectors that have a maximum width of 0.325 inches (8.255 mm).

The terminals also accommodate copper wire without lugs (insulation stripped back). Torque the screws to approximately 9 pound-force inches (1 Newton meter).

Set screw barrel terminal strip: Use #12 to #24 AWG wire with insulation stripped back. Tighten the screws to approximately 4.5 pound-force inches (1 Newton meter).

Caution: For screw-down barrier terminal strip outputs, use #12 AWG wire to prevent personnel contact with the voltages (NEBs standard, Class A2).

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).

4.9External Alarm Contact Connectors

Connect each set of external alarm contacts to a local alarm system as required (see Figure 21). Wrap terminal block pins using #22 to #26 AWG copper wire with insulation stripped back.
