the internal transfer switch is automatically acti-
vated, the inverter is turned “Off”, and the
inverter’s loads will operate from external AC
input.
3.10.4 Units having the “B1” option require a
separate 120 VAC, 20 amp input circuit. The "T"
or "T1" option circuit activates the internal trans-
fer switch supplying utility or generator power to
the inverter’s output loads, and turns “Off” the
inverter. The "B1" option input circuit activates
the battery charger. Both the transfer switch
input and the battery charger input must be
connected to the same phase AC power source.
Charger Rating

12/1800N Up to 15 Amp AC 85 Amp DC
12/3000N Up to 20 Amp AC 105 Amp DC
4. START UP/OPERATION
4.01The battery charger will operate any-
time that there is external AC power and the
battery is not 100% charged. The status lights
will indicate that there is external power and the
battery’s condition.
4.02 If the unit has the "B1" option, there are
two switches on the right side that should be
adjusted.
4.03 The switch labeled "Battery Type" should
be set to the correct setting based on the compo-
sition of the batteries attached to the inverter.
Use the following table to determine the correct
setting.
BATTERY TYPE SELECTION
SETTING
BATTERY TYPE
A Vented Nickel-Cadium 10 cells
B Vented Lead-Acid (Antimony)
Flooded Electrolyte
C Sealed Lead-Acid Absorbed or
Vented Nickel-Cadium 9 cell
D Sealed Lead-Acid Gelled
NOTE: Used batteries should be put through 5
charge cycles with the switch set one position lower
(to the right) than desired. Example: Start a used
vented-lead acid battery on the "C" setting.
4.04 The switch labeled "Battery Size"
should be set to the correct setting based on the
total amp hour capacity of the batteries attached
to the inverter. Use the following table to determine
correct setting.
BATTERY CAPACITY SELECTOR
SETTING AMP HOUR CAPACITY
A
Over 600
B
600 - 400
C
400 - 200
D
Less than 200
4.05 To operate the inverter, turn the On/
Off switch to “ON”. Assure that the output break-
ers are reset. If a remote switch is used, the
inverter is turned “On” or “Off” by the remote
switch.
