Safety precautions
xviii
• For information on the required capacity and other specifications of a
noise filter, see the General Documentation - Hardware.
A properly selected noise filter can reduce conducted electric noise significantly.
• Provide the last SERVOPACK module with a terminating connector.
Otherwise malfunction could result.
• Ensure that the voltage of the AC power supply to a converter is equal to
the rated voltage of that converter.
Otherwise injury or a fire could result.
• Do not subject the inverters or converters to a high-voltage withstanding
test.
Otherwise their semiconductor components would be damaged.
• Wiring to the inverters or converters must be done according to the rele-
vant wiring drawing.
Otherwise they could be damaged.
• The screws of a terminal block must be tightened to a specified torque.
Otherwise a fire could result.
• Never connect an AC main power supply to the U/T1, V/T2, and W/T3 out-
put terminals.
Otherwise the inverter would be damaged.
