POWER CONNECTION
The unit is supplied with power leads 1 meter 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) AWG12 wire. The wire colours are:
All connections should be made inside an appropriate junction box. Refer to the specications
table for the correct sizing of the circuit breaker in the distribution panel.
A ground stud is provided to bond the chassis to local ground to reduce or eliminate EMI.
To ensure spark free connections the power switch must be in the OFF position prior to making
the connections to the battery bank(s).
The unit may be hooked to 1 or 2 battery banks. If you are hooking up 2 battery banks keep in
mind that they MUST share a common ground!
Operation
Prior to turning on the unit, you must decide on which charging prole, 2 or 3 stage charging,
to use. To help you decide, please see the following section entitled 2 or 3 Stage Charging to
determine the charging prole.
Once you have decided on the charging prole you must set the switch to the correct posi-
tion. The switch is located to the right of the output terminal on the front panel. 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 briey, and then the green OUTPUT ON LED will
illuminate.
When the unit is rst turned on, it will charge the batteries at maximum current and the
charging light will be on. After a period of time which may be minutes to hours, the batteries
will reach the absorption voltage (3-stage) or oat voltage (2-stage), and the charging current
will reduce as necessary to maintain the batteries at that voltage. Once the charging current
has dropped to a low level (about 10% of the charging current rating), the charging light will
go off, and if set to 3-stage charging the voltage will drop to the oat level. You may check
