BAT+ & BAT- 5/16 in. stud mount for battery input, be careful to observe proper
polarity.
CHAS Chassis or earth ground (green wire) should be connected here.
NEUT Neutral or return line (white wire) of the AC output.
INVOUT Hot or AC output of the inverter (black wire).
NO Normally open contact of the relay. When the “COIL” terminal is
energized, this contact is connected to “C” (common terminal).
When the “COIL” terminal is not energized, this contact is not
connected to “C” (common terminal).
C The common terminal of the relay.
NC Normally closed contact of the relay. When the “COIL” terminal is
energized, this contact is not connected to “C” (common terminal).
When the “COIL” terminal is not energized, this contact is
connected to “C” (common terminal).
RMT Remote terminal. Applying battery negative to this terminal will turn
the inverter ON. Use a switch connected to battery negative and
the remote terminal to turn on the unit remotely. This terminal has
no significant current demand.
UTIL When utility AC power is connected to the “NO” terminal, this
terminal can be used with a jumper to energize the “COIL” when
utility is on.
COIL The coil contact of the relay. This must be connected to the INV
terminal to function as an alarm and can have either UTIL or INV
jumpered to it to function in a transfer switch.
INV A low current output of the inverter voltage to drive the relay.
INSTALLATION
CAUTION: Be sure to disconnect all DC power to the installation wiring. Be sure to
disconnect both the batteries and the chargers which may be connected. Make all
connections to the inverter BEFORE connecting DC power to the battery.
