6.5 Changing the Power Chassis Voltage Setting
This section covers changing the voltage selection for systems that need a different
voltage setting for the PA-4 power chassis.
Changing From 380-415 VAC to 200-240 VAC
Complete the following procedure to change the AC voltage setting from 3-phase
380-415
VA C to 3-phase 200-240 VA C. (Refer to your robot manual for information on
connecting AC power to the PA-4 power chassis.)
Part 1 – Insulating the Power Chassis Power Cord
Refer to Figure 6-2 for this procedure.
1. Make sure the power chassis and controller are turned off. Disconnect the PA-4
chassis from the AC power source. Verify that power remains off during all parts
of this procedure.
2. If a 5-wire plug has already been installed, remove the plug.
3. This procedure requires two user-supplied pieces of shrink tubing; one 7 mm
(1/4-inch) in diameter, the other 19 mm (3/4-inch).
4. Place the 7 mm (1/4-inch) shrink tubing over the end of the blue wire in the
power cord and use a heat gun to apply it.
5. Fold the blue wire back.
6. Place the 19 mm (3/4-inch) shrink tubing over the blue wire and the power cord
insulation and use a heat gun to apply it.
7. Install a 4-wire plug (or wire directly to an appropriate service disconnect). Refer
to your robot manual for PA-4 power cord specifications.
DANGER: Electrical hazard!
Changing the voltage setting in the power chassis must be
done by a trained, authorized person. The power supply
can injure or kill a person who does not perform this
procedure correctly.
DANGER: High AC voltage is coupled through capacitors
to the blue wire of the PA-4 power chassis power cord. If
you change the voltage setting from 380-415
VAC to
200-240
VA C, you must add additional insulation to the
blue wire according to the directions provided below.
Failure to do this could result in injury or death.
