8) Power Voltage and Power Code Connection
A. Voltage Specification
· Match the indication of voltage to specification of power code and connect the cable.
1. Must not use on condition that voltage specification is different.
2. In case of change the using voltage, refer to article [Power Voltage Changing Method].
· Single-phase connection (100V, 110V, 120V, 200V, 220V, 240V)
· Three-phase connection (200V, 220V, 240V, 380V, 440V)
B. Power Voltage Changing Method
· In voltage of 110V series, 220V series and 380~440V specification, you can change into the voltages as follows
by just changing the location of power voltage switching connector.
■ Voltage change of 100~220V specification
Trans former Model: KM-2070P-110
■ Voltage change of 220V specification
Trans former Model: KM-2070P-220
If power voltage switching connector is wrongfully set, control box can be damaged.
In case that changes voltages between the phases 110V series and 220V series and 380V~440V
series transformer should replace.
