Installation
MOUNTING
Mount the unit and allow at least 4 inches of clearance around the heat sink fins for adequate
cooling.
POWER CONNECTION
The unit is supplied with power leads about 8 feet long. This should normally be adequate to
connect to a source of power. If you must extend the power leads, be sure to use at least a
good quality (typeTEW) AWG 8 gauge wire. The wire colours are:
Operation
Once you have decided on the charging profile you must set the switch to the correct
position. Set the switch to the correct position as shown on the label.
To turn the unit on, simply move the power switch to the ON position. The alarm buzzer will
sound and the Low Output LED will come on briefly, and then the green OUTPUT ON LED will
illuminate.
When the unit is first turned on, it will charge the batteries at a constant current and
the charging light will be on. After a period of time, which may be minutes to hours, the
batteries will reach the float voltage at which time the charging light will go off, and the
charging current will reduce as necessary to maintain the batteries at that voltage. You may
check this voltage at the output terminals of the unit with a good digital voltmeter.
110 VAC
Black/Brown - AC Hot
White/Blue - AC Neutral
Green - Ground
All connections should be made inside an appropriate junction box. The maximum current
draw from the 110 VAC supply is 14 amps, so a 20 amp circuit breaker should be used in the
circuit panel.
The unit is supplied with two AWG 8 gauge wires. The red wire is the output positive. The
black wire is the output negative.
