FRAME GROUNDING
The frame of the VIPER must be properly grounded.
A ground terminal marked
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
PROCEDURE
When changing input voltages, it is necessary to
change the settings behind the access door on the
side of the machine.
WARNING
Failure to do so may result in damage to the
machine.
------------------------------------------------------------------------
To reconnect the VIPER, follow the directions as out-
lined below. Follow this procedure ONLY while the
VIPER is disconnected from the input power and the
capacitors have properly discharged.
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.
For 550 to 575 : Position the large switch to 550-575.
3. Move the "A" lead to the appropriate terminal.

RECONNECTION
USE ON ENGINE DRIVEN POWER SUPPLIES
The VIPER can be used on engine driven power sup-
plies. However, the following AC Wave Form Voltage
and Input Power Restrictions do apply.
AC Wave Form Restrictions
The VIPER can be operated on engine driven genera-
tors as long as the engine drive output meets the fol-
lowing 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 greater than 230VAC +/-
15%.
*The 230 VAC auxiliaries of Lincoln engine drives
meet these conditions when run in the high idle mode.
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 VIPER may be lim-
ited due to the output capacity of the engine driven
power supply. The following are recommended output
current settings when used with various Lincoln and
Red-D-Arc engine driven power supplies.
