Installation
MOUNTING
Mount the unit in a DRY location. Mount the unit in a ventilated area. Allow at least 1 inch of
clearance around the unit for adequate cooling.
It is NOT recommended that the unit be secured until it has been tested under the intended
load.
POWER CONNECTION
Use a voltmeter to measure the input voltage to ensure the voltage of the battery is within the
Input Voltage range printed on the front of the unit.
The High-Voltage and Low-Voltage alarm setpoints are now infinitely adjustable between the
minimum and maximum allowable input voltages for these inverters.
The adjustment is made by using a small flat-blade screwdriver to turn the potentiometer
which is accessible through the HI-LO switch opening on the front of the inverter. Setting the
potentiometer fully counter-clockwise sets the low and high voltage alarms to their lowest
settings. Turning the potentiometer fully clockwise sets the low and high voltage alarms to
their highest settings.
If the voltage alarm goes off during normal operation, first confirm that the battery voltage is
within the normal range for your battery system. If it is, then adjust the alarm setpoints by
turning the potentiometer slightly clockwise if the Low Battery alarm is ON, or counter-clock-
wise if the High Battery alarm is ON.
The unit is supplied with two 5 foot power cables. This should be adequate to connect to a
power source.
Connect the wires as follows:
Red - Positive
Black- Negative
CAUTION
: The case of the inverter is connected to AC Ground and AC Neutral to meet regulatory
requirements and to reduce the possibility of it generating any radio frequency interference. The
case must be bonded appropriately to the grounding system of the vehicle or marine vessel. On a
vehicle bond the case to the frame and on a marine vessel bond the case to the hull. A grounding
stud is provided on the front of the inverter for this purpose. To ensure proper grounding, check the
connection with an ohmmeter.
CAUTION:
Do not mount the unit where explosive gases may accumulate as a slight arc may
occur when the power leads are connected, and in the unlikely event of a failure, sparks may be
generated inside the unit.
