Ensure The Cooling - ABB ACS880-04 Kurzanleitung Für Die Installation

Measure the insulation resistance of the motor and motor cable when the motor cable
is disconnected from the drive. 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 be greater than 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.

through the drive.
Install the drive module into a cabinet
See figure B:
• Install the punched section to the back of the cabinet frame.
• Remove the pedestal guide plate from the bottom of the drive module.
• Install the support rails and pedestal guide plate to the cabinet bottom frame.
• Install the telescopic insertion ramp to the pedestal guide plate.
See figure C:
• Remove the sheeting from the clear plastic shrouds from both sides.
See figure D:
• 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 mounting bracket to the drive module.
• Install the top metallic shroud to the drive module.
• Install the back shrouds to the drive module.
See figure E:
• 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.
