INPUT ELECTRICAL
CONNECTIONS
Before installing the machine, check that input supply
voltage, phase, and frequency are the same as the
machine's voltage, phase, and frequency as specified
on the machine's rating plate.
The Pro-Cut 55 should be connected only by a quali-
fied electrician. Installation should be made in accor-
dance with all local and national codes (eg: U.S.
National Electrical Code) and the information detailed
below.
SINGLE PHASE INPUT CONNECTION
FOR 208/230/460 VOLT MACHINES
The 208/230/460 Volt Pro-Cut 55 is supplied with one
11 ft. #8 AWG 3-conductor input power cord (with a
molded 230 VAC plug on one end) already connected
to the machine. When received from the factory, this
machine is internally connected for 230 VAC. Re-con-
nection will be necessary if a higher or lower input
voltage is used.
CONVERTING A 208/230/460 VOLT
MACHINE FROM SINGLE PHASE TO
THREE PHASE INPUT
To convert to three phase power, the 230 VAC 3-con-
ductor power cord must be removed and replaced
with a #10 AWG 4-conductor power cord.
1. Connect the green lead to ground per U.S. National
Electrical Code.
2. Connect black, red and white leads to power.
THREE PHASE POWER INPUT CONNEC-
TION FOR 200/380-415 VOLT & 460/575
VOLT MACHINES
The 200/380-415 Volt and 460/575 Volt Pro-Cut 55's
are supplied with one 10 ft. #10 AWG 4-conductor
input power cord already connected to the machine.
When received from the factory, these machines are
internally connected for the higher input voltage. Re-
connection will be necessary if a lower input voltage is
used.
INSTALLATION
CONVERTING 200/380-415 VOLT &
460/575 VOLT MACHINES FROM THREE
PHASE TO SINGLE PHASE INPUT
To convert to single phase power, the 4-conductor
input cord may still be used, but the red lead must be
disconnected and insulated.
1. Connect the green lead to ground per U.S. National
Electrical Code.
2. Connect black and white leads to power
3. Wrap red lead with tape to provide 600V insulation.
INPUT POWER CORD CONNECTOR
INSTALLATION
A cord connector provides a strain relief for the input
power cord as it passes through the left rear access
hole. The cord connector is designed for a cord diam-
eter of .40 - 1.03 in (10.2 - 26.2mm) if it becomes nec-
essary to install a different input cord.
CORD REMOVAL:
1. Unplug line cord from the receptacle.
NOTE: DO NOT PERFORM THE NEXT STEP UNTIL
THE HIGH VOLTAGES INSIDE THE MACHINE
HAVE BEEN ALLOWED TO DISSIPATE, APPROXI-
MATELY TWO MINUTES.
------------------------------------------------------------------------
2. Remove wraparound by unscrewing the eleven
screws on the case sides and top.
3. Unscrew the two screws that hold the line switch
onto the case front.
4. Pull the line switch out of the case front.
5. Angle the line switch so the screws on the near
side of the switch can be loosened.
6. Loosen the screws and remove the existing cord
from the switch.
7. Remove the nut, lock washer, plain washer and
green lead off of the ground screw assembly.
8. Loosen the cable connector on the case back.
9. Pull the line cord out of the machine, carefully feed-
ing it under the aluminum bracket as you pull.
CORD INSTALLATION:
1. Feed the new cord through the cable connector
and into the machine, carefully feeding it under the
aluminum bracket.
