• main (air circuit) breaker when available for the particular drive type.
￭ Plinth height (oC164 and +C179)
The standard height of the cabinet plinth is 50 mm. These options specify a plinth height of
100 mm (+C164) or 200 mm (+C179).
￭ Seismic design (C180)
The option involves seismic capability according to International building code 2012, test
procedure ICC-ES AC-156. The installation level must not exceed 25% of the height of the
building, and
S
DS
(installation site specific spectral acceleration response) must not exceed
2.0 g .
The option adds the following accessories and features:
• reinforced plinth
• flat bars at base of the cabinet for fastening.
￭ Empty cubicles (oC199…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 lead-throughs both at the top and the bottom.

Dimensions of empty cubicles (oC199, +C200, +C201) (page 237) .
￭ Resistor braking (oD150 and +D151)
See chapter Resistor braking (page 265) .
￭ EMC filters ( E202)
EMC filter for first environment TN (grounded) system, category C2. More information:

System

￭ Sine filter (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 (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.
