Electrical Installation:
The CTD 200R Series Cut-Off Saws use 2 H.P. single or three phase 3450 RPM, 60 HZ TEFC (totally enclosed fan
cooled) motors on a NEMA 56Z Frame. CTD uses a speed up drive so that the blade will run at approximately 3700
RPM. The motor is turned “ON” and “OFF” using the manual overload starter located on the top of the motor.
Electrical installation should be performed by a qualified and certified electrician. It is highly recommended
that a
lock-out
or
disconnect switch
be located close to the machine between your main electrical panel and
the machine. This disconnect switch is used to shut off power to the machine and should be used whenever
the blades are changed, or at any time the machine is serviced and the blade is exposed. A manual overload starter has
been provided as a standard feature. The starter protects the motor from overheating and will not allow the motor to restart
itself after power outages or undervoltage situations. A Magnetic Starter is also available as an optional accessory.
Electrical Installation of Power to Starter by a Qualified Electrician:
All wiring from the motor to the starter has been completed and tested at the factory several times.
The voltage has been clearly tagged.
DO NOT CONNECT ANY VOLTAGE THAT IS DIFFERENT THAN
THE TAGGED VOLTAGE, AS THIS MAY CAUSE SEVERE DAMAGE AND DANGER.
Consult the factory
if any changes are needed.
Bring power lines to the top of the Manual Overload Starter or Magnetic Starter. Use dust proof connectors if available.
Single Phase Motors:
Connect leads to L1 (line 1) and L2 for single phase motors. (See Wiring Diagram for Single Phase Motors
below.) Green ground wire must be grounded to enclosure. If using type “SO” wire and plug, use a romex
connector through starter box and a grounded plug.
Be sure to check rotation.
The blade must rotate down
and to the rear on the underside of the blade (see Diagram “D” on Page No. 5). If a change in rotation is necessary, switch
the #8 and #5 wires in the electrical box on the motor. Rotation is set at factory for single phase motors.
Three Phase Motors:
Connect incoming power line leads to L1 (line 1), L2 and L3. (See Wiring Diagram for Three Phase Motors
below). Green ground wire must be grounded to enclosure.
Be sure to check rotation
as polarities may be
different. The blade must rotate down and to the rear on the underside of the blade (see Diagram “D” on
Page No. 5).
If a change in rotation is necessary, reverse any two of the incoming power wires.
Example: If the blades
are running backwards and incoming wires are connected White L1, Black L2, Red L3, switch the Black
wire with the Red so that Black is connected to L3 and Red is connected to L2. This will change the motor
to rotate properly.
