Important:
Following notes must be considered when planning and installing:
• The motor is protected by overheat by a PTC thermo sensor; witch can be connected on terminal 7, or
by a thermo regulator in the motor coils.
• Do not use a frequency dependent motor protection switch, use motor protection relay.
• If the motor wires are switched off at e.g. emergency stop, must the terminal 8 OFF input also be
switched off to avoid overload when restarted.
• Never connect mains supply at the output terminal U V W.
• Never use a “Megger” on the frequency inverter (Isolation test).
• Power up’s - unlimited.
• Install inverter after the EMC rules. See section 2.11
• Control wires must be separated from mains wires and motor wires.
