FRAME GROUNDING

The frame of the PYTHON 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.

WARNING

Failure to do so may result in damage to the machine.

------------------------------------------------------------------------

To reconnect the PYTHON, follow the directions as outlined below. Follow this procedure ONLY while the PYTHON 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.

USE ON ENGINE DRIVEN POWER SUPPLIES

The PYTHON 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 PYTHON can be operated on engine driven gen- erators 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 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 PYTHON 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.
