Examine the installation
Examine the drive installation site. Make sure that:
•
The installation site is sufficiently ventilated or cooled to remove heat from the drive.
•
The ambient conditions of the drive meet the specifications. See
•
The material below the drive is non-flammable.
•
The installation surface is as close to vertical as possible and strong enough to
support the drive.
•
There is sufficient free space around the drive for cooling, maintenance and operation.
For the minimum free space requirements, see
requirements.
•
There are no sources of strong magnetic fields such as high-current single-core
conductors or contactor coils near the drive. A strong magnetic field can cause
interference or inaccuracy in the operation of the drive.
Make sure that the drive is compatible with the grounding
system
You can connect the drive to symmetrically grounded TN-S system (center-grounded
wye). If you install the drive to a different system, you may need to remove the varistor
screw (disconnect the varistor circuit).

IEC installation
Do not remove EMC or Do not remove EMC or
VAR screws. VAR screws.
NEC installation
EMC and VAR screws are removed as default.
1)
A residual current device must be installed in the supply system. In NEC installations the residual current
device is only required at or above 1000 amps.
2)
ABB does not guarantee the EMC category or the operation of the ground leakage detector built inside the drive.
Install the drive module in a enclosure
Step Task
1 Install the punched section to the back of the enclosure frame.
2 Install the support rails and pedestal guide plate to the enclosure bottom frame.
3 Install the telescopic insertion/extraction ramp to the pedestal guide plate.
4 Option +B051: Remove the sheeting from the clear plastic shrouds from both sides.
5 Install the fastening bracket to the drive module.
6 Option +B051: Install the bottom grille to the drive module if there is no bottom plate in the
enclosure and degree of protection of IP20 is needed for the drive module from the bottom
side.
7 Option +B051: Install the top metallic shroud to the drive module.
8 Option +B051: Install the back shrouds to the drive module.
9 To prevent the drive module from falling, attach its lifting lugs with chains to the enclosure
frame.
10 Push the drive module into the enclosure along the telescopic insertion/extraction ramp.
11 Remove the ramp.
12 Attach the drive module to the pedestal guide plate.
13 Attach the drive module from its top to the punched section at the enclosure back. Note:
The fastening bracket grounds the drive module to the enclosure frame.
