The Xantrex XW Automatic Generator Start
975-0239-01-01 5–17
This manual for use by qualified personnel only
Connecting an External Manual ON/OFF Switch (Optional)
The external manual ON/OFF inputs (wires 7 and 8 on the wiring harness) are
intended for wiring to one or more remote O
N/OFF switches for starting and
stopping the generator manually. The other contact of the switch should be
connected to ground. In order for the Xantrex XW Automatic Generator Start to
be able to detect these switches, wire the positive of the generator battery to the
constant 12-volt/24-volt generator battery positive (wire 10 on the Xantrex XW
Automatic Generator Start wiring harness). See Figure 5-7.
If the generator battery does not have the required voltage, any 12-volt or 24-volt
power source will suit this purpose. If an alternate power source is used, the
negative of the power source must be connect to the other contact of the switch.
Multiple control panels or simple contact closures can be wired to the external
manual O
N/OFF inputs. The Xantrex XW Automatic Generator Start detects if any
of the contacts close and will change its operating mode to External Manual On
or External Manual Off (for more information, see the Xantrex XW Automatic
Generator Start Owner’s Guide). The Xantrex XW Automatic Generator Start turns
the generator on or off according to these inputs and the resulting operating
mode change.
The External Manual On and External Manual Off states are not affected by
maximum generator run time. See the Xantrex XW Automatic Generator Start
Owner’s Guide for additional information.
CAUTION: Equipment Damage
Do not connect the Xantrex XW Automatic Generator Start to a 48-volt battery
bank. The Xantrex XW Automatic Generator Start is limited to a 30V open-circuit
maximum by its regulatory approval and cannot be connected to a 48-volt power
source. Furthermore, tapping 12-volts or 24-volts from a 48-volt battery bank will
unevenly wear out the batteries and shortens the battery bank life.
