Disconnect the Cam-Lok™ connectors in the following order;
1.
Blue – Line 3 (only used on 3-phase systems)
2.
Red – Line 2
3.
Black – Line 1
4.
White – Neutral
5.
Green – Ground
Conductor sizes must be adequate to handle the maximum cur-
rent 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. If ALUMINUM con-
ductors are used, apply corrosion inhibitor to conductors. After
tightening terminal lugs, carefully wipe away any excess corrosion
inhibitor.
Tighten terminal lugs to the torque values as noted inside the
transfer switch door.
Use a torque wrench to tighten the conduc-
tors, making sure not to overtighten, or dam-
age to the switch base could occur. If under-
tightened, a loose connection would result,
causing excess heat which could damage the
switch base.
Be sure to maintain proper electrical clearance between live metal
parts and grounded metal. Allow at least 1/2 inch for 100-400
Amp circuits.
2.4.1
GENERATOR ANNUNCIATOR CONNECTIONS
A terminal strip is provided to make the annunciator connections.
A multi-conductor cable is provided for this purpose(100 foot).
Route the multi-conductor cable into the TMS enclosure, be sure to
keep cable away from power leads. Secure in place using ty-wraps
or other appropriate fasteners. Connect the wires to the terminal
strip matching the functions declared on the terminal strip decal.

3.1 FUNCTIONAL TESTS AND
ADJUSTMENTS
Following transfer switch installation and interconnection, inspect
the entire installation carefully. A competent, qualified electrician
should inspect it. The installation should comply strictly with all
applicable codes, standards, and regulations. When absolutely
certain the installation is proper and correct, complete a functional
test of the system. Perform functional tests in the exact order
presented in this manual, or damage to the switch could result.
For 3-phase systems only; verify the voltage setting of the voltage
sensing relay matches the system voltage. Adjust nominal voltage
and undervoltage percent as necessary.
IMPORTANT: Before proceeding with functional tests, read and
make sure to understand all instructions and information in this
section. Also read the information and instructions of labels and
decals affixed to the switch. Note any options or accessories that
might be installed and review their operation.
3.2 MANUAL OPERATION – LOAD TRANSFER
3.2.1
CLOSE TO NORMAL SOURCE SIDE
Before proceeding, verify the position of the transfer switch mech-
anism by observing the position of the circuit breaker handles that
are used in the manual transfer switch. If the Utility Supply circuit
breaker handle is on (up position) the Customer Load is connected
to the Utility Supply. No further action is required.
If the Generator Supply circuit breaker handle is ON (up position)
the Customer Load is connected to the Generator Supply. Move
Generator Supply circuit breaker handle to the OFF (down posi-
tion). Move slider bar to the right side until it stops. Move Utility
Supply circuit breaker handle to the ON (up position). Customer
Load is now connected to the Utility Supply.
3.2.2
CLOSE TO GENERATOR SOURCE SIDE
Before proceeding, verify the position of the transfer switch mech-
anism by observing the position of the circuit breaker handles that
are used in the manual transfer switch. If the Generator Supply
circuit breaker handle is on (up position) the Customer Load is
connected to the Generator Supply. No further action is required.
If the Utility Supply circuit breaker handle is ON (up position) the
Customer Load is connected to the Utility Supply. Move Utility
Supply circuit breaker handle to the OFF (down position). Move
slider bar to the left side until it stops. Move Generator Supply
circuit breaker handle to the ON (up position). Customer Load is
now connected to the Utility Supply.
D o not use excessive force when operating
the transfer switch manually or damage to
the mechanisms could occur.
