4.5Connecting Output Power

Output power is supplied to the equipment through screw-down barrier terminal strips located on the rear of the chassis. Each bus has separate strips for each fuse type. The terminal screws are of various sizes corresponding to the current load of the fuses. Each individual output has two terminals, battery (BATT) and return (RTN).

Connections are typically made using ring or spade-type connectors crimped onto the output power wires. Table 1 on page 8 gives terminal screw size, maximum terminal width, and AWG

#accepted for copper wire. In selecting wire size, follow local code referring to the ampacity guidelines provided in Appendix A of this manual.

Connect the output BATT and RTN terminals (see Figure 17) for each fused circuit to the appropriate set of terminal strips. Use the appropriate wire size with appropriate size crimp-on spade lugs or ring connectors or use the appropriate size wire with insulation stripped back at the wire end. Tighten the screws to approximately 9 pound force-inches (1 Newton-meter) of torque.
