INSTALLATION AND WIRING
General Information
All Vigilant
®
transfer switches are factory-tested and approved.
Installation requires the mounting of the transfer switch as well
as all external wiring for utility and generator operation. Once
the transfer switch is properly installed, it should be visually
inspected and approved before any testing is performed.
Mounting Location
IMPORTANT: Vigilant
®
series transfer switches do not
support Delta configurations.
!
WARNING
Always use adequate lifting to lift and mount the
transfer switch during installation.
All Vigilant
®
transfer switches require that adequate lifting
means are used to install the switch at its mounting location.
Be certain to choose a location that offers a flat mounting
surface that is capable of supporting the transfer switch (see
Vigilant
®
400A/600A Specifications on page 8
for proper
weight details). Caution must be taken at the installation site to
make sure the site is free from excessive moisture, fluctuating
temperature ranges, dust, corrosive materials, etc. Before any
drilling takes place, be certain the drilling area is free of any
hazards including electrical wiring, piping, etc. Extreme caution
should be exercised when any installation and drilling are
performed to protect the transfer switch from any debris including
contaminants, filings, etc. Any debris within the transfer switch
may result in a system malfunction.
Mounting Requirements
The enclosure has a NEMA (National Electrical Manufacturer’s
Association) type 3R rating and is suitable for indoor/outdoor
installations and provides a degree of protection against falling
rain and sleet. Guidelines for mounting the unit include:
•
Ensure that the mounting surface can support the weight of
the switch and adheres to all local codes.
•
The enclosure must be installed with NEMA type 3R hardware
and connections.
•
Level and plumb the unit enclosure to prevent deformation.
•
Never install the switch where any corrosive substance may
come in contact with the enclosure.
•
Protect the switch at all times against excessive moisture, dust,
dirt, lint, construction grit and corrosive vapors.
Recommended Upstream Protection
When protected by a circuit breaker rated at 600A maximum
for 400A rated transfer switches, this switch is suitable for use
on a circuit capable of delivering not more than 10,000A RMS
SYMMETRICAL AT 480V.
When protected by a circuit breaker rated at 800A maximum
for 600A rated transfer switches, this switch is suitable for use
on a circuit capable of delivering not more than 12,000A RMS
SYMMETRICAL AT 480V.
Use copper or aluminum wiring 60/75C rating for power
terminals.
!
CAUTION
Using upstream protection devices other than the circuit
breakers with the recommended ratings given above may
cause improper operation of the Vigilant
®
switch.
!
WARNING
Always de-energize power connections before
installing any connections. Power lines may
carry high voltage. Exercise extreme caution
when installing any power connections to the
Vigilant
®
switch.
