SECTION 1 INSTALLATION ASCO Series 7000 Automatic Closed–Transition Transfer Switches are factory wired and tested. Field installation simply requires mounting and connection of service cables, and auxiliary control circuits (if required). De–energize the conductors before making any line or auxiliary circuitry connections. Be sure that Normal and Emergency line connections are in proper phase rotation. Place engine generator starting control in the OFF position.
PAGE 4
INSTALLATION Tighten bolted joints to the torque specified in Table A. The engine control contact connections (if used) are located on the transfer switch. Connect signal wires to appropriate terminals as specified in Table B and shown in Figure 1–1. The reliablility of the connection depends on how clean and how tight the joint is. Table B. Engine start connections Table A.
