2.1 INTRODUCTION TO INSTALLATION
This equipment has been wired and tested at the facto-
ry. Installing the switch includes the following proce-
dures:
• Mounting the enclosure.
• Connecting power source and load leads.
• Connecting the generator start circuit.
• Connecting any auxiliary contact (if needed)
• Installing/connecting any options and accessories.
• Testing functions.
2.2 UNPACKING
Carefully unpack the transfer switch. Inspect closely for
any damage that might have occurred during shipment.
The purchaser must file with the carrier any claims for
loss or damage incurred while in transit.
Check that all packing material is completely removed
from the switch prior to installation.
Attach any lifting device to the transfer switch mounting
holes or brackets only. DO NOT LIFT THE SWITCH AT
ANY OTHER POINT.
2.3 MOUNTING
Mounting dimensions for the transfer switch enclosure
are in this manual. Enclosures are typically wall-mount-
ed. Components are generally mounted in a standard
NEMA 1-type enclosure. A NEMA 12, 3R, 4 & 4X are
also available. See TRANSFER SWITCH OPTIONS,
Section 3.15.
Handle transfer switches carefully when
installing. Do not drop the switch. Protect the
switch against impact at all times, and against
construction grit and metal chips. Never install a
transfer switch that has been damaged.
Install the transfer switch as close as possible to the
electrical loads that are to be connected to it. Mount the
switch vertically to a rigid supporting structure. To pre-
vent switch distortion, level all mounting points. If nec-
essary, use washers behind mounting holes to level the
unit.
2.4 CONNECTING POWER SOURCE AND
LOAD LINES
Make sure to turn OFF both the normal (Utility)
and standby (generator) power supplies before
trying to connect power source and load lines to
the transfer switch. Supply voltages are extreme-
ly high and dangerous. Contact with such high
voltage power supply lines causes extremely haz-
ardous, possibly lethal, electrical shock.
Wiring diagrams and electrical schematics are provided in
this manual. Power source and load connections are made
at a transfer mechanism, inside the switch enclosure.
2.4.1 2-POLE MECHANISM
This switch (Figure 2.1) is used with a single phase sys-
tem, when the single phase NEUTRAL line is to be con-
nected to a Neutral Lug and is not to be switched.

(100 Amp Shown)
2.4.2 3-POLE MECHANISM
This switch (Figure 2.2) is used with a single phase sys-
tem, when the single phase NEUTRAL line is to be
switched during transfer; or with a 3-phase system,
when NEUTRAL is not to be switched.
