Instruction Manual

Aux Output Connections
975-0400-01-01 Revision H 2–23
This manual is for use by qualified personnel only.
The auxiliary output connectors can accept #22 to #14 AWG (0.5 to 1.5 mm
2
)
copper solid or stranded wire. The auxiliary output is short-circuit protected and
is disabled when a ground fault occurs.
To use the solar charge controller to control loads and protect your batteries, you
must connect the solar charge controller auxiliary output to a relay that controls a
battery disconnect to disconnect the load from the batteries. As shown in Figure
2-12, the auxiliary output can also power a fan to vent the battery compartment.
The solar charge controller auxiliary output (producing 5 to 13 V and up to 200
mA) must be configured to activate when the batteries reach a pre-set voltage
level. See “Configuring the Auxiliary Output” on page 3–13.
NOTICE
EQUIPMENT DAMAGE
Do not connect a high amperage device to the auxiliary output. The auxiliary
output is intended only to energize a low-current circuit such as a relay coil.
Connecting to a high-amperage device will open the fuse in the common line
and possibly damage the unit.
Failure to follow these instructions may damage the equipment.
