3.4 System ON/OFF Switch
Use this rocker switch to turn the system ON and OFF and to reset the system. This switch is located on the front
panel of the system. If placed in the “OFF” position, this switch will override the operation of a remote ON/OFF
switch connected to terminals 7 and 8 of the Options connector shown in Figure 3-1 – Customer Terminations.
WARNING:
The System ON/OFF Switch does not interrupt the DC input power to the system, so it must be
noted that dangerous DC voltages still exist inside the unit, even if the power switch is turned off.
3.5 Remote Signal Contacts
Terminal Contacts provide capabilities for Remote Inverter Power ON/OFF and Power indication, Remote Low
Battery Warning indication, and Gen Start/Auto-Throttle control. Contacts are rated 2 amps at 12 volts, Class 2
circuits. Wiring connections are made through an 8 position Options terminal block. Screw pressure-clamp
terminals accept up to 14-gauge wire.
A remote power switch will control the system by tying terminals 7 and 8 of the options connector (shown in
Figure 3-1) together. This will actuate an internal relay that turns the control power on. The Power On/Off switch
on the front panel defeats this remote switch.
In addition, a terminal for a remote LED indicator is provided (terminal 6) with a current limiting resistor integral to
the circuit.
