3.1.4 General Precautions for Wiring
(1) Power Supply Capacities and Power Losses
The following tables show the power supply capacities and power losses of the multi-winding drive unit,
SERVOPACKs, and converters.
The values are for two pairs of a SERVOPACK and converter.

(2) How to Select Molded-case Circuit Breaker and Fuse Capacities
The following tables show the current capacities and inrush current of the multi-winding drive unit, SERVO-
PACKs, and converters.
Use these values as a basis for selecting the molded-case circuit breaker and fuse. The values are for two pairs
of a SERVOPACK and converter.

The table above also provides the nominal values of current capacity and inrush current. Select a fuse and a
molded-case circuit breaker which meet the cutoff characteristics shown below.
• Main circuit, control circuit: No breaking at three-times the current values of the table for 5 s.
• Inrush current: No breaking at the same current values of the table for 20 ms.
