Installation
2.1 INTRODUCTION TO INSTALLATION
This equipment has been wired and tested at the factory. Installing
the switch includes the following procedures:
• Unpacking the TMS.
• Mounting the enclosure.
• Connecting power source and load leads.
• Testing functions.
2.2 UNPACKING
Carefully unpack the transfer switch. Inspect closely for any dam-
age 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.
2.3 MOUNTING
Mounting dimensions for the transfer switch enclosure are in this
manual. This enclosure is configured for wall-mounting using the
tabs provided, top and bottom.
The TMS-200 is supplied with a removable mounting bracket. It is
shipped from the factory attached to the top mounting brackets.
If desired the mounting bracket can be removed from the enclo-
sure and mounted to the wall first. Once the mounting bracket is
attached to the wall the enclosure can be mounted to the bracket. It
is necessary to use all mounting points provided, top and bottom.
The TMS-200 is supplied with strips of foam gasket material.
This foam can be attached to the rear face of the enclosure. It is
suggested to install the foam as close as possible to the outside
edge to seal off the gap between the enclosure and the surface it
is mounted to.
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 prevent switch distortion, level all
mounting points. If necessary, use washers behind mounting holes
to level the unit.

2.4 CONNECTING UTILITY AND LOAD LINES
M ake sure to turn OFF the NORMAL
(UTILITY) power supply and unplug the
GENERATOR power supply before connect-
ing the 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 will cause
extremely hazardous, possibly lethal, electri-
cal shock.
The Utility power source and customer load connections are
made on the circuit breakers. Access to the terminals is gained by
removing the inner cover over the circuit breakers.
Conduits entering the enclosure need to be attached with a water-
tight connector listed for the wet locations. This is required to
maintain the UL type 3R rating. If installed indoors, conduit/cable
entry can be made with standard conduit connectors. Standard
terminal lugs on all customer connection points are solderless,
screw-type.
Connect power source and load conductors to clearly marked
terminal lugs on the TMS as follows:
• UTILTY (Normal supply) leads: Ungrounded conductors connect
to the top of the Utility Supply circuit breaker. Neutral connec-
tion is made at the 5-position terminal marked Neutral. Ground
connection is made at the 2-2 conductor lugs marked GND.
• CUSTOMER LOAD leads: Ungrounded conductors connect
mechanical lugs attached to the busbars at the bottom of the
circuit breakers. Neutral connection is made at the 5-position
terminal marked Neutral. Ground connection is made at the 2-2
conductor lugs marked GND.
• GENERATOR: This connection is made at the Cam-Lok™ ter-
minals.
B efore connecting or disconnecting the
generator output leads from the Cam-Lok™
connectors be sure to open generator output
circuit breaker and turn off generator.
The Cam-Lok™ connectors are not rated for making or interrupting
current. Make sure that the generator is off and the output circuit
breaker is open before connecting or disconnecting Cam-Lok™
connectors.
Connect the Cam-Lok™ connectors in the following order;
1.
Green – Ground
2.
White – Neutral
3.
Black – Line 1
4.
Red – Line 2
5.
Blue – Line 3 (only used on 3-phase systems)
