the work, they must do wiring as the terminal voltage and poles by the manual for
prevention of the device damage or the injury to personnel.
Fig.3.2 Typical wiring for the main circuit
MCC ： Breaker FIL ：Disturbance filter
TB ： Isolated transformer KM1 ：AC contactor
R/C ： Surge inhibitor P, D ：Reserve
■ The breaker should be selected B type short circuit device, the drop-away current is
more1.3 times than servo rated input one, otherwise is less than 1.05 times than the
servo rated input current.
■ Single phase power supply AC220V(+10%～－15％) can be employed when the
precision is comparative low and the power is less than 0.8KW for servo unit, and its
the wiring is as fig.3.2
■ While connecting the terminals, peel the insulative surface of the wire and twist the
naked copper wires, compress the wiring by the pre-insulation cold pressing terminals
to fasten the connection.
