Planning the electrical installation

Note 2:
Explosion-safe (EX) motors
The motor manufacturer should be consulted regarding the construction of the motor insulation and
additional requirements for explosion-safe (EX) motors.
Note 3:
High-output motors and IP 23 motors
For motors with higher rated output than what is stated for the particular frame size in EN 50347 (2001)
and for IP 23 motors, the requirements of range “100 kW <
P
N
< 350 kW” apply to motors with
40 kW <
P
N
< 100 kW. The requirements of range “
P
N
> 350 kW” apply to motors with
P
N
within the
range of “100 kW <
P
N
< 350 kW”.
Note 4:
HXR and AMA motors
All AMA machines (manufactured in Helsinki) to be supplied by a drive have form-wound windings. All
HXR machines manufactured in Helsinki since 1997 have form-wound windings.
Note 5:
ABB motors of types other than M2_, M3_, HX_ and AM_
Select according to non-ABB motors.
Note 6:
Resistor braking of the drive
When the drive is in braking mode for a large part of its operation time, the intermediate circuit DC
voltage of the drive increases, the effect being similar to increasing the supply voltage by up to 20
percent. The voltage increase should be taken into consideration when determining the motor insulation
requirement.
Example: Motor insulation requirement for a 400 V application must be selected as if the drive were
supplied with 480 V.
Permanent magnet synchronous motor
Only one permanent magnet motor can be connected to the inverter output.
Install a safety switch between a permanent magnet synchronous motor and the
motor cable. The switch is needed to isolate the motor during any maintenance work
in the drive.
Supply connection
Disconnecting device (means)
ACS800-01, ACS800-U1, ACS800-02 and ACS800-U2 without the enclosure extension,
ACS800-04, ACS800-U4
Install a hand-operated input disconnecting device (means) between the AC power
source and the drive. The disconnecting device must be of a type that can be locked
to the open position for installation and maintenance work.
ACS800-U2 with the enclosure extension, ACS800-07 and ACS800-U7
These units are equipped with a hand-operated input disconnecting device (means)
which isolates the drive and the motor from the AC power as standard. The
disconnecting device does not, however, isolate the input busbars from the AC
power. Therefore during installation and maintenance work on the drive, the input
cables and busbars must be isolated from the input power with a disconnector at the
distribution board or at the supplying transformer.
