￭
Empty cubicles on left (options +C199…C201)
The option adds an empty 400, 600 or 800 mm wide cubicle to the left end of the
line-up. The cubicle is equipped with blank power cable entries both at the top and
the bottom.
The cubicle is equipped with blank panel entries (full panel or two-half panels) on the
back.
￭
Resistor braking (options +D150 and +D151)
See chapter Resistor braking (page 333).
￭
EMC filter (option +E202)
EMC filter for 1st Environment (category C2) for TN (grounded) system.
￭
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 has
a dedicated cooling fan.
￭
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 condensation inside the cabinet when the drive is not in operation.
The power output of the heating elements increases when the surrounding air
temperature is low and decreases when the surrounding air temperature is high. The
customer must stop the heating when it is not needed by disconnecting the heater
supply voltage.
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.
