2 POWER LINE PROTECTION

The Servopack is operated through the commercial power line (200 V). To prevent the power

line accidents due to grounding error, contact error, or to protect the system from a fire, circuit
breakers

or fuses must be installed according to the number of Servopack used (Table

2).

A quick-melting fuse cannot be used, because the Servopack used the capacitor-input

power supply and the charging current might melt such a fuse.
