INSTALLATION
PRO-CUT 55
A-3
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.
a. The Pro-Cut 55 should be connected only by a
qualified electrician. Installation should be made in
accordance with the U.S. National Electrical Code,
all local codes and the information detailed below.
b. When received directly from the factory, the
machines are internally connected for 230 VAC.
Re-connection will be necessary if a higher input
voltage is used. To reconnect the Pro-Cut to 460
VAC or to connect back to 230 VAC, follow the
directions as outlined below. Follow this procedure
ONLY while the Pro-Cut is disconnected from the
input power and the capacitors have properly dis-
charged.
1. Open the access door on the side of the
machine.
2. For 200 to 230 : Position the large switch
to 200-230.
For 400 to 460 : Position the large switch
to 400-460.
3. Move the "A" lead to the appropriate termi-
nal.
INPUT POWER CORD CONNECTOR
INSTALLATION
The Pro-Cut 55 is supplied with one 11' #8 AWG 3
lead input power cord already connected to the
machine. 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 diameter of .40 - 1.03 in (10.2 - 26.2mm) if it
becomes necessary to install a different input cord.
For three phase connection: Replace input power cord
with a #10 AWG 4 lead cable.
1. Connect leads of input power cord to a fused
power panel. Make sure the green lead is con-
nected to the panel and the panel is connected to
a good earth ground.
Install in accordance with all local and national electric
codes.
FRAME GROUNDING
The frame of the Pro-Cut 55 must be properly ground-
ed. A ground terminal is mounted on the case bottom
directly behind the input power switch for this purpose.
The cable that is sent attached to the machine is con-
nected to this ground terminal. See the National
Electric Code for details on proper grounding meth-
ods. Install in accordance with all local and national
electrical codes.
