This manual for use by qualified personnel only
Mounting the Unit
The XW Automatic Generator Start is to be mounted vertically on a wall with the
connectors facing downwards.
To mount the XW Automatic Generator Start:
1. Hold the unit flush and square against the wall, panel, or horizontal surface.
• If the mounting surface requires pre-drill holes for the screws, use the supplied
mounting template to mark, then drill, four holes.
2. With a Phillips screwdriver and the supplied #6 screws, secure each corner of the XW
Automatic Generator Start to the mounting surface.
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 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 ON/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.
