INSTALLATION
PRO-CUT 80
A-4
FRAME GROUNDING
The frame of the Pro-Cut 80 must be properly ground-
ed. A ground terminal marked 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 connected to this ground terminal. See the
National Electric Code for details on proper grounding
methods. Install in accordance with all local and
national electrical codes.
INPUT VOLTAGE RECONNECTION
PROCEDURE
When changing input voltages, it is necessary to
change the settings behind the access door on the
side of the machine. Failure to do so may result in
damage to the machine.
To reconnect the Pro-Cut, follow the directions as out-
lined below. Follow this procedure ONLY while the
Pro-Cut is disconnected from the input power and the
capacitors have properly discharged.
1. Open the access door on the back 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.
For 550 to 575 : Position the large switch to 550-575.
3. Move the "A" lead to the appropriate terminal.
USE ON ENGINE DRIVEN POWER SUPPLIES
The Pro-Cut 80 can be used on engine driven power
supplies. However, the following AC Wave Form
Voltage and Input Power Restrictions do apply.
AC Wave Form Restrictions
The Pro-Cut 80 can be operated on engine driven
generators as long as the engine drive output meets
the following conditions:
The AC wave form frequency is between 45 and 65
Hz.
For 200 - 230 VAC Supplies:
The AC wave form peak voltage must be below 420
volts.
The RMS voltage must be 230VAC +/- 15%.
* The 230 VAC auxiliaries of Lincoln engine drives
meet these conditions when run in the high idle
mode.
For 380 - 415 VAC Supplies:
The AC wave form peak voltage must be below 840
volts.
The RMS voltage must be 400 VAC +/- 10%.
For 460 VAC Supplies:
The AC wave form peak voltage must be below 840
volts.
The RMS voltage of the AC wave form must be 460
VAC +/- 10%.
Input Power Restrictions
The available output current of the Pro-Cut 80 may be
limited due to the output capacity of the engine driven
power supply. The following are recommended output
current settings when used with various Lincoln
engine driven power supplies.
