Xantrex Technology XW4024-120/240-60, XW4548-120/240-60, XW6048-120/240-60 Mounting the Unit

XW System Accessories Installation

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

CAUTION: Shock Hazard

All installation wiring should be performed by a qualified installer or electrician.

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.

ELV Circuits	ELV (Extra-Low Voltage) circuits have an open-circuit voltage of not more than 30 Vrms
	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/Voc 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:
	Table 5-1Circuit Limitations
	Circuit Parameter	Circuit Maximum
	Open circuit voltage (Voc)	30 V maximum
	Overcurrent protection
	(fuse size for open circuit voltage up to 20 V)	5 A maximum
	Overcurrent protection	5 A to 3.33 A
	(fuse size for open circuit voltage from 20 V to 30 V)	(100/Voc amps
		maximum)
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).
