The sine filter option consists of three single-phase reactors and delta-connected capacitors
at the output of the drive. The filter is fitted in a separate cubicle and has a dedicated cooling
fan.
￭ Common mode filter (option +E208)
The common mode filter contains ferrite rings mounted around the AC output busbars in
the drive module. The filter protects the motor bearings by reducing the bearing currents.
More information on when the option is required: See section Examining the compatibility
of the motor and drive (page 86).
￭ Molded case circuit breaker (MCCB, option +F289)
This option replaces the standard main switch with a molded case circuit breaker. The
breaker has inbuilt protection functions against overload and short-circuit. It is operated with
a direct rotary handle on the cabinet door.
For North American market only.
￭ Cabinet heater with external supply (option +G300)
The option contains:
• heating elements in the cubicles or supply/inverter modules
• load switch for providing electrical isolation during service
• miniature circuit breaker for overcurrent protection
• terminal block for external power supply.
The heater prevents humidity condensation inside the cabinet when the drive is not running.
The power output of the semiconductor-type heating elements depends on the environmental
temperature. The customer must switch the heating off when it is not needed by cutting the
supply voltage off.
The customer must supply the heater from an external 110…240 V AC power source.
For the actual wiring, see the circuit diagrams delivered with drive.
￭ Cabinet lighting (option +G301)
This option contains LED lighting fixtures in each cubicle (except joining and brake resistor
cubicles) and a 24 V DC power supply. The lighting is powered from the same external
110…240 V AC power source as the cabinet heater (option +G300).
￭ Terminals for external control voltage (option +G307)
The option provides terminals for connecting an external uninterruptible control voltage to
the control unit and control devices when the drive is not powered.
