•
Attach the drive module to the pedestal guide plate.
•
Attach the drive module from its top to the punched section at the cabinet back.
Note
:
The fastening bracket grounds the drive module to the cabinet frame.
Measure the insulation of the input and motor cables and
the motor
Before you connect the input power cable to the drive, measure its insulation according to
local regulations.

. Ground the motor cable shield at the motor end. For minimal
interference, make a 360-degree grounding at the cable entry, or keep the pig tail short.
Measure the insulation of the motor and motor cable when the motor cable is
disconnected from the drive, see figure
. Measure the insulation resistance
between each phase conductor and the Protective Earth conductor using a measuring
voltage of 1000 V DC. The insulation resistance of an ABB motor must exceed 100 Mohm
(reference value at 25 °C). For the insulation resistance of other motors, refer to the
manufacturer’s instructions.
Note:
Moisture inside the motor casing reduces the insulation
resistance. If you suspect moisture, dry the motor and repeat the measurement.
Check the grounding system compatibility
EMC filter compatibility
The drive has an internal EMC filter (+E210) as standard. However, for the UL (NEC) drive
types, the filter is disconnected as default. The filter is typically not needed in North
American installations.
Ground-to-phase varistor compatibility
The drive is equipped with an internal ground-to-phase varistor as standard. However, for
the UL (NEC) drive types, the ground-to-phase varistor is disconnected as default.
Connect the power cables (and install the shrouds for
B051)

1
Install the grounding terminal to the drive module base.
2
Run the motor cables to the cabinet. Ground the cable shields 360 degrees at
the cabinet entry.
3
Connect the twisted shields of the motor cables to the grounding terminal.
4
Screw in and tighten the insulators to the drive module by hand. Install the
T3/W2 connection terminal to the insulators.
WARNING!
Do not use longer screws or greater tightening
torque than given in the installation drawing. Doing either can
damage the insulator and cause dangerous voltage to be
present at the module frame.
5
Connect the phase T3/W2 conductors to the T3/W2 terminal.
6
Install the T2/V2 connection terminal to the insulators. See the warning in step 4.
