7-7-2 Wiring equipments
Select the wiring equipment, refer to the table below.
1. On the input power side, a molded case circuit breaker
(MCCB) to protect driver primary wiring should be in
stalled.
2. A leakage current breaker threshold of 200mA and above
is recommended.
3. Use of input side magnetic contactor. An input MC can
be used to prevent an automatic restart after recovery
from an external power loss during remote control opera-
tion. However, do not use the MC reduced reliability.
4. In general, magnetic contactors on the output of the
driver should not be used for motor control. Starting a
motor with the driver running will cause large surge cur-
rents and the driver overcurrent protector to trigger.
