See figure D on page 95 :
•
Install the mounting bracket to the drive module.
•
For B051:
•
Install the bottom grille to the drive module if there is no bottom plate in the cabinet
and degree of protection of IP20 is needed for the drive module from the bottom
side.
•
Install the top metallic shroud to the drive module.
•
Install the back shrouds to the drive module.
See figure E on page 95 :
•
Attach the drive module to the cabinet frame with chains.
•
Push the drive module into the cabinet along the telescopic insertion ramp.
•
Remove the ramp.
See figure F on page 95 :
•
Attach the drive module to the pedestal guide plate.
•
Attach the drive module from top to the punched section at the cabinet back. Note :
The mounting bracket grounds the drive module to the cabinet frame.
Check the insulation of the input and motor cables and
the motor
Check the insulation of the input cable according to local regulations before you connect it
to the drive.
See figure H on page 96 . Ground the motor cable shield at the motor end. For minimal
interference, make a 360-degree grounding at the cable lead-through, or keep the pig tail
short.
Check the insulation of the motor and motor cable when the motor cable is disconnected
from the drive, see figure
I on page 96 . Measure the insulation resistance between each
phase conductor and then 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 or 77 °F). For the insulation
resistance of other motors, consult the manufacturer’s instructions.
Note: Moisture inside
the motor casing will reduce the insulation resistance. If you suspect moisture, dry the
motor and repeat the measurement.
Connect the power cables (and install the shrouds for
B051)
See figure G on page 96 .
