Changing Voltage Setting for Power Chassis (From 380-415 VAC to 200-240 VAC)
2.26 Changing Voltage Setting for Power Chassis
(From 380-415 VAC to 200-240 VAC)
If you need to change the AC voltage setting from 3-phase 380-415 VAC to 3-phase
200-240 VAC, you must follow the three-part procedure below. This procedure must be
performed by a skilled person and should be completed before installing the power
chassis. (Also see “Connecting AC Power to the Adept PA-4 Power Chassis” on page 109).
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 Power Chassis Power Cord (All Systems)
WARNING: 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 VAC, 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.
1. Make sure the power chassis and controller are turned off. Disconnect the
controller and the optional Security Panel from the AC power source. Verify that
power remains off during all parts of this procedure.
2. Disconnect the 5-wire power chassis power cord at the power source from the
AP2.T1,T2,T3, Neutral, and Protective Earth terminals on the Security Panel.
3. Locate the two pieces of shrink tubing in the accessory kit; one is 7 mm (1/4-inch)
diameter, the other is 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 (see Figure 2-41).
5. Fold the blue wire back and.
6. Re-install the power chassis power cord at the Security Panel according to the
200-240 VAC section in Table 2-12 (see also Figure 2-37).
