Carefully read the instruction manual before setting the unit.
■ Default setting
The default settings are as specified below at the delivery time. Set them according to the working conditions.
The input circuit of this product is the common use of 3 - phase 3 -wire (3φ3W), single -phase 2 -wire (1 φ2W), and single -phase
3 -wire (1 φ3W). In case an input circuit is designated at the case of an order, it is shipped by the default value of the
designated input circuit. And, in case it does not do designation of the input circuit (with no designation), it is shipped by the
defaul t value of 3 - phase 3 -wire (110V).
The unit will be delivered with your specified setting values, if so specified.
