UNITS WITHOUT ENCLOSURE
The wires from the terminals labeled DK1 and DK2 on the battery charger must be connected
across the starter motor. One lead must go to ground and the other must go to the starter
motor (or the 'switched' B+ on the Starter Solenoid). DK1 and DK2 are not polarity sensitive
and are therefore interchangeable with one another.
Wires from the terminals labeled B+ and B- on the Battery Charger go to the battery on the
generator set. B+ goes to the positive post of the battery and B- goes to the negative post on
the battery.
It is important, not only functionally, but also for safety reasons
that the Generator set, transfer switch and battery charger
share a common Ground and neutral.
To determine the proper type and gauge of wire to use for
connecting the generator set, transfer switch, and battery
charger together, you should consult a local licensed electrician.
