OPERATION

Once the inverter has been fully installed and wired, and DC power has been
applied, the inverter is ready to turn on. The Status LED beneath the AC wiring box
on the left side of the inverter shows the current state of the inverter.

Inverter Power Mode

The inverter can now be turned on by using the local or remote switch. When the
inverter is on, the local Status LED will be a constant green. When the Local
On/Off switch is enabled in assemblies without the "R" suffix, any switch may turn
on or off the inverter. When using the local switch, any remote switch must be a
momentary type.
With the "R" suffix, only the remote switch will turn on the inverter. The remote
switch must be a snap type. The Local On/Off switch will be inactive.
The function of the switch will depend on the mode the unit is running in, and if the
Aux tab is enabled and being used.
Note: The LED will blink a yellow-green pattern indicating the battery type on the
12LPC15 during the first 5 minutes of operation upon initial power-up. The
pattern will cease if a warning or fault occurs.

External Power Mode - Bypass

The loads attached to the inverter output will operate directly from the external AC
power line independently of the inverter ON/OFF status. If the inverter is left ON
(standby mode), the built-in bypass relay will automatically cycle back and forth between
"Inverter Power" mode and "External Power" mode depending on the availability of the
external AC power line.

External Power Mode -Battery Charger

T he battery charger will engage automatically and independently of the inverter
ON/OFF status. The 3-step charging process modes are: Constant Current (Bulk),
Constant Voltage (Acceptance), and Float. The Battery Temperature Sensor (BTS) must
be plugged into the "TEMP SENSE" connector on the inverter. If not, the charger will
not operate.
