Handle transfer switches carefully when install-
ing. Do not drop the switch. Protect the switch
against impact at all times, and against con-
struction grit and metal chips. Never install a
transfer switch that has been damaged.
This transfer switch is mounted in a CSA type 3R enclosure. It can be
mounted outside or inside and should be based on the layout of instal-
lation, convenience and proximity to the utility supply and load center.
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 prevent switch distortion, level all mounting
points. If necessary, use washers behind mounting holes to level the
unit.

CONNECTING POWER SOURCE
AND LOAD LINES
Make sure to turn OFF both the UTILITY
(NORMAL) and GENERATOR ( STANDBY)
power supplies before trying to connect power
source and load lines to the transfer switch.
Supply voltages are extremely high and danger-
ous. Contact with such high voltage power sup-
ply lines causes extremely hazardous, possibly
lethal, electrical shock.
Wiring diagrams and electrical schematics are provided in this
manual.
NOTE:
All installations must comply with national, state and local
codes. It is the responsibility of the installer to perform an instal-
lation that will pass the final electrical inspection.
The utility supply connection is made at the UTILITY SERVICE
DISCONNECT circuit breaker terminals located in the left side of the
enclosure. The generator and customer supply load connections are
made at the transfer switch mechanism, located in the right side of the
enclosure. Each compartment has a neutral lug to connect the neutral
conductors of each supply and load. A ground lug is provided in the
right side compartment for connection of the ground wires.
The inside cover of the enclosure is split in two sections and each
side can be accessed independently. It will be necessary to remove
the inside covers of the enclosure to make the power connections to
the Utility supply circuit breaker and the transfer switch. It will also
be necessary to remove the plastic cover over the utility supply con-
nections by sliding it perpendicular to the face of the circuit breaker.
