Use the following procedure to connect the input power cables to the circuit breaker panel:
1. Obtain four lengths of #2 AWG wire for use as the input power cables.
2. Strip back 7/8 inches of insulation from one end of each wire as shown in Figure 12 .
Figure 12. 2-Hole Lug Terminal Installation
3. Slide a 2-inch length of heat shrink insulation over the end of each wire.
4. Terminate one end of each wire with the 2-hole lug terminals provided (requires crimper).
5. Slide the heat shrink insulation down to the lug terminal so the barrel end of the terminal is covered.
6. Use a heat gun to apply heat to the heat shrink insulation until it tightens around the wire
and barrel end of the terminal.
7. Use the nuts (with captive locking washers) and flat washers provided to secure the input
power wires to the specified terminals and as shown in Figure 13 :
• BATT (–) wires: Connect to BATT (–) terminals on A and B input power terminal blocks.
• RTN (+) wires: Connect to RTN (+) terminals on A and B input power terminal blocks.
8. Use a torque wrench (with a 7/16-inch socket) to tighten the input power terminal block
nuts to 32 pound-force inches (3.6 Newton meters) of torque.
9. Route the free end of each input power cable to the office battery source.
10. Connect the input power cables to the office battery power source in accordance with
applicable local electrical codes and/or National Electrical Codes. Do not apply power to
the circuit breaker panel until instructed to do so for testing (see
Section 4, Testing ).
Caution: Caution should be taken to not reverse the input wires to the circuit breaker panel.
Within the panel, the internal return wiring is not protected by circuit breakers. If the wires are
reversed, current will flow through the unprotected return wiring in the panel to the equipment.
This condition can cause damage to the equipment in the frame in which the panel is installed
and to equipment in adjacent frames
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.
