3-12. Changing over the supply voltage
DANGER :
1. To avoid electrical shock hazards, turn OFF the power and open the control box cover after about
five minutes have passed.
2. Open the control box cover after turning OFF the power without fail. Then, changing over the supply
voltage.
This product uses a power transformer for changing over the voltage.
If you want to change over the supply voltage, change over the voltages of both of the MC-702 electrical
box and the electrical box of the AW-3 device.
① Changing over the supply voltage of the MC-702 electrical box
The electrical box can be used with the supply voltage 220 / 220 / 230 / 240 V by changing over con-
nection terminal ❷ of the accessory terminal block supplied for power transformer ❶ .
When changing over the supply voltage, change over terminal ❷ according to the table shown below.
