INTRODUCTION

This manual has been prepared especially for the
purpose of familiarizing personnel with the design,
application, installation, operation and servicing of
the applicable equipment. Read the manual carefully
and comply with all instructions. This will help to
prevent accidents or damage to equipment that might
otherwise be caused by carelessness, incorrect application, or improper procedures.
Every effort has been expended to make sure that the
contents of this manual are both accurate and current. The manufacturer reserves the right to change,
alter or otherwise improve the product at any time
without prior notice.

1.2

EQUIPMENT DESCRIPTION

The automatic transfer switch is used for transferring
critical electrical loads from a UTILITY (NORMAL)
power source to an EMERGENCY (GNERATOR)
power source.
The transfer switch prevents electrical feedback
between the UTILITY and EMERGENCY sources. For
that reason, electrical codes require a transfer switch
in all standby electric system installations.
When the transfer switch is connected to the engine
generator control panel, the control panel constantly
monitors the UTILITY voltage and controls the operation of the transfer switch.
Should the UTILITY voltage drop below a preset value,
and remain at this low voltage for a preset amount of
time, the generator cranks and starts. After the generator starts, the transfer switch transfers the load
circuits to the generator, the generator then supplies
the loads. When UTILITY returns above a preset level
the load is transferred back to the UTILITY and the
generator shuts down.

1.3

TRANSFER SWITCH DATA LABEL

A DATA LABEL is permanently affixed to the transfer
switch enclosure. Use this transfer switch only with
the specific limits shown on the DATA LABEL and
on other decals and labels that may be affixed to the
switch. This will prevent damage to equipment and
property.
When requesting information or ordering parts for this
equipment, make sure to include all information from
the DATA LABEL.
Record the Model and Serial numbers in the space
provided below for future reference.

power supplies before trying to connect power
source and load lines to the transfer switch.
Supply voltages are extremely high and dangerous. Contact with such high voltage power supply lines causes extremely hazardous, possibly
lethal, electrical shock.
Wiring diagrams and electrical schematics are provided in this manual. Power source and load connections are made at the transfer mechanism, inside the
switch enclosure.

Solderless, screw-type terminal lugs are standard.
The conductor size range is as follows:
Switch Rating

Wire Range

400A

(1) #4-600 MCM or
(2) 1/0-250 MCM

Conductor sizes must be adequate to handle the maximum current to which they will be subjected; based
on the 75°C column of tables, charts, etc. used to size
conductors. The installation must comply fully with
all applicable codes, standards and regulations.
Before connecting wiring cables to terminals, remove
any surface oxides from the cable ends with a wire
brush. All power cables should enter the switch next
to transfer mechanism terminals. If ALUMINUM conductors are used, apply corrosion inhibitor to conductors. Tighten terminal lugs to the torque values as
noted on the decal located on the inside of the door.
After tightening terminal lugs, carefully wipe away
any excess corrosion inhibitor.
All power cables should enter the switch next to the
