92 Guidelines for planning the electrical installation
The abbreviations used in the tables are defined below.
Abbr. Definition
U n Nominal AC line voltage
Û LL Peak line-to-line voltage at motor terminals which the motor insulation must
withstand
P n Motor nominal power
du/dt du/dt filter at the output of the drive
CMF Common mode filter of the drive
N N-end bearing: insulated motor non-drive end bearing
n.a. Motors of this power range are not available as standard units. Consult the
motor manufacturer.

Additional requirements for explosion-safe (EX) motors

If you use an explosion-safe (EX) motor, follow the rules in the requirements table above.
In addition, consult the motor manufacturer for any further requirements.
Additional requirements for ABB motors of types other than M2_, M3_, M4_, HX_
and AM_
Use the selection criteria given for non-ABB motors.

Additional requirements for braking applications

When the motor brakes the machinery, the intermediate circuit DC voltage of the drive
increases, the effect being similar to the motor supply voltage increasing by up to
20 percent. Consider this voltage increase when specifying the motor insulation
requirements if the motor will be braking a large part of its operation time.
Example: Motor insulation requirement for a 400 V AC line voltage application must be
selected as if the drive were supplied with 480 V.

Additional requirements for the regenerative and low harmonics drives

It is possible to increase the intermediate circuit DC voltage from the nominal (standard)
level with a parameter in the control program. If you choose to do this, select the motor
insulation system which withstands the increased DC voltage level.

Additional requirements for ABB high-output and IP23 motors

The rated output power of high output motors is higher than what is stated for the
particular frame size in EN 50347 (2001).
