1.6.3 Safety Interlock Connector
Located on the left side of the rear panel, as viewed from the rear, are the remote interface connectors and
safety interlock connectors. The 15-pin D-sub miniature female safety interlock connector provides two
separate interlock loops. Pins 1 and 8 are used for situations where the amplifier can be left on, but forced into
STANDBY mode. This interlock is called Inhibit Interlock. Pins 10 and 14 are used for situations that
demand the safest possible condition, with the AC power to all main circuits disconnected. This interlock is
called AC Interlock. Both loops must be closed, or jumpered, for normal operation.
