￭ CSA Approved (option +C134)
The option includes the following accessories and features:
• bottom entry and exit of cables with US cable conduit entry (plain plate without ready-made
holes)
• all components UL/CSA listed/recognized
• maximum supply voltage 600 V
• main (air circuit) breaker when available for the particular drive type.
￭ Plinth height (options +C164 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 (option +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 mechanics
• flat bars at base of the cabinet for fastening.
￭ Empty cubicles on right (options +C196…C198)
The option adds an empty 400, 600 or 800 mm wide cubicle to the right 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.
￭ 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.
￭ du/dt filter (option +E205)
The du/dt filter protects the motor insulating system by reducing the voltage rise speed at
the motor terminals. The filter also 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).
￭ 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).
