4.8 Output Power Connectors
Connect the output BATT and RTN terminals for each fuse circuit on each set of terminal strips
as follows (see Figure 20):
•Screw-downbarrier 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).
•Setscrew 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).

4.9 External 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.
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.
Caution: For screw-down barrier terminal strip outputs, use #12 AW G 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).
