50 Operation principle and hardware description

Sine filter (option +E206)


A sine filter provides true sinusoidal voltage waveform at the drive output by suppressing
the high-frequency voltage components of the output. These high-frequency components
cause stress to motor insulation as well as output transformer saturation (if present).
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 it has a
dedicated cooling fan. The filter increases width of the drive by 600 mm (23.62 in.) or 1000
mm (39.37 in.).
More information: see page 83.

Common mode filter (option +E208)


The common mode filter contains ferrite rings mounted around the motor output of the
drive (R6 to R9) and around the output busbars in the power module (R10 and R11). The
filter protects the motor bearings by reducing the bearing currents.
More information on when the option is required: See section
of the motor and drive

Line contactor (option +F250)


This option provides a line contactor with a manual operating switch on the cabinet door.

Flange mounted switch for MCCB (option +F277)


This option allows you to open and close the main switch from the side of the cabinet.
For US market only with option +F289.

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 US market only.

Cabinet heater with external supply (option +G300)


The option contains:
•
heating elements in the cubicles where needed
•
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.
The option is not available with +C134 (CSA Approved).
