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.
