V. AUX OUTPUT
The output terminal strip provides an additional output to accommodate 12 volt accessories, such
as Kussmaul’s 12 VDC air pump. The AUX output works in conjunction with a front panel mounted
DIP switch. For normal operation, the DIP switch should be left in AC mode, which means that the
aux accessory works only when shoreline power is supplied to the charger. With the switch in DC
mode, the aux accessory will operate when AC power is ON or OFF. If AC power is off, the aux ouput
operates from the vehicle’s batteries.
VI. LED STATUS INDICATORS
a. POWER:
Green LED, indicates AC power is present.
b. SYSTEM:
See specifications page for description of system status
.
VII. COOLING FAN
The AC 4000,LPC is fan cooled and automatically cycles on and off depending on output current.
When the fan is on, air is circulated and exhausted through the right side. The fan cycles briefly when
power is applied in order to verify that it is functioning.
