This manual for use by qualified personnel only
Wiring to the 20-contact Connector
ELV Circuits ELV (Extra-Low Voltage) circuits have an open-circuit voltage of not more than
30 V
rms
or 42.2 VDC or peak, and are therefore not a shock hazard.
Class 2 Circuits As per the US National Electrical Code (NEC) and the Canadian Electrical Code
(CEC), available power in Class 2 circuits is limited to 100 VA, usually by current
limiting by means of overcurrent protection or series resistance. The current is
limited to 5 A for circuits with open-circuit voltage of 20 V, and to I=100/V
oc
for
circuits with open circuit voltage between 20 V and 30 V.
Circuit Limitations The relay contacts in the Xantrex XW Automatic Generator Start are rated at 5 A
maximum and all circuits on the 20-contact connector are rated at 30 V
maximum.
Ensure that all circuits connected to the 20-contact connector obey the
following limits:
Wiring Harness Connections to the generator, thermostats, and external O
N/OFF switches are
made using a wiring harness that plugs into the 20-contact connector
(see Figure 5-8).
The wires on the wiring harness can be extended to meet installation
requirements. When extending the wire harness, ensure that the extension wires
are the same color as the wires on the harness.
WARNING: Fire, Shock, and Energy Hazards
The 20-contact connector is intended for connection to Class 2 ELV (Extra Low
Voltage) circuits only. Do not exceed the circuit limitations specified in the
following section.
CAUTION: Shock Hazard
All installation wiring should be performed by a qualified installer or electrician.
