The OPCB has a Test button which forces the unit to act as if an
overload has occurred. This button operates even when the transfer
signal is inactive.

TRANSFER SWITCH DATA DECAL

A DATA DECAL is permanently affixed to the transfer switch enclo-
sure. Use this transfer switch only within the specific limits shown on
the DATA DECAL 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 DECAL.
Record the Model and Serial numbers in the space provided below for
future reference.

TRANSFER SWITCH ENCLOSURE

The standard switch enclosure is a National Electrical Manufacturer's
Association (NEMA) and UL 3R type. UL and NEMA 3R (indoor/out-
door rated) type enclosures primarily provide a degree of protection
against falling rain and sleet; is undamaged by the formation of ice on
the enclosure.

SAFE USE OF TRANSFER SWITCH

Before installing, operating or servicing this equipment, read the
SAFETY RULES (inside front cover) carefully. Comply strictly with all
SAFETY RULES to prevent accidents and/or damage to the equip-
ment. The manufacturer recommends that a copy of the SAFETY
RULES are posted near the transfer switch. Also, be sure to read all
instructions and information found on tags, labels and decals affixed
to the equipment.
Two publications that outline the safe use of transfer switches are the
following:
• NFPA 70; National Electrical Code
• UL 1008, STANDARD FOR SAFETY-AUTOMATIC TRANSFER
SWITCHES
It is essential to use the latest version of any standard to ensure
correct and current information.

INTRODUCTION TO INSTALLATION

This equipment has been wired and tested at the factory. Installing the
switch includes the following procedures:
• Mounting the enclosure.
• Connecting power source and load leads.
• Connecting the generator start and sensing circuit.
• Connecting any auxiliary contact (if needed)
• Overload Prevention Control Board loads (as required)
• Testing functions.
2.2

MOUNTING

Mounting dimensions for the transfer switch enclosure are in this
manual. See the "Installation Diagram" section.

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.
Install the transfer switch as close as possible to the electrical loads
that are to be connected to it. The switch enclosure is suitable for wall
or floor mounting. For wall mounting, remove the floor stands to gain
access to the mounting points on the bottom of the enclosure. Mount
the switch vertically to a rigid supporting structure. For floor mounting,
place switch enclosure on a hard, level surface. Secure enclosure to
the floor. To prevent switch distortion, level all mounting points. If nec-
essary, use washers behind mounting holes to level the unit.
