Changing Voltage Setting for Power Chassis
To change the AC voltage setting from 3-phase 380-415 VAC to 3-phase 200-240 VAC,
follow the two-part procedure below. This procedure must be done only by a skilled
person and should be performed before installing the power chassis.
WARNING: Electrical hazard!
Changing the voltage setting in the power chassis must be done by a
skilled person. The power supply can injure or kill a person who does not
perform this procedure correctly.
Part 1 – Insulating the Blue Wire in Power Cord
WARNING: High AC voltage is coupled through EMI capacitors to the
blue wire of the PA-4 power chassis power cord. To change the voltage
setting from 380-415 VAC to 200-240 VAC, insulate the blue wire
according to the directions provided below.
1. Turn off the Adept PA-4 Power Chassis and the Adept MV Controller.
2. Disconnect the 5-wire power chassis power cord from the AC power source.
3. Locate the two pieces of shrink tubing in the accessories kit; one is 7 mm (1/4
inch) diameter, the other is 19 mm (3/4 inch).
4. Place the 7 mm shrink tubing over the end of the blue wire in the power cord and
use a heat gun to apply it. See Figure 2-21.
5. Fold the blue wire back and place the 19 mm shrink tubing over the end of the
power cord. Use a heat gun to apply the shrink tubing.
