* 3. A preventive circuit for inrush current is not built in the 24 VDC control power supply. The
protective circuit must be designed by the customer.
* 4. Make sure the current capacity is accurate. For the SERVOPACK with the cooling fan built-
in, an inrush current flows; 200 % of the current capacity in the table above for two seconds,
when turning ON the control circuit power supply to start the fan working.
Note: Do not use a fast-acting fuse. Because the SERVOPACK's power supply is a capacitor
input type, a fast-acting fuse may blow when the power is turned ON.
The SGDH SERVOPACK does not include a protective grounding circuit. Install a ground-fault protector
IMPORTANT
to protect the system against overload and short-circuit or protective grounding combined with the molded-
case circuit breaker.
