AC and DC connections direct to the AC and DC circuit breakers in accordance with diagram 2.2 below.
Caution:
Small sense leads are connected to the output side of the DC breaker. These must remain
connected to the output side of the breaker after installation of the DC cabling, or the charger will not
function properly.

Connection should be made by a qualified installer in accordance with national and local electrical codes.
The installer should determine the gauge of wire to be used based on the length of cable run and the
ampere requirements of the charger. Size the DC cabling to keep voltage drop in the charging leads as
low as possible.
Refer to TABLE 2.2 for the charger’s AC requirement of your charger. The input voltage and frequency
are marked on the charger’s front panel. Maximum current consumption will be approximately 75% to
80% of the breaker’s rating. Typical efficiency is 85% for 24 volt units, 88% for 48 volt units and 91%+
for 120 and 240 volt units. Power factor is approximately 0.8 at rated input voltage.
WARNING:
The battery charger must be connected to a grounded permanent wiring system. A ground
stud or terminal is provided for this purpose
