What this chapter contains
This chapter contains preventive maintenance instructions.
Safety
WARNING! Read the Safety instructions on the first pages of this manual before
performing any maintenance on the equipment. Ignoring the safety instructions can
cause injury or death.
WARNING! The drive module is heavy [frame size R7: 100 kg (220 lb), frame size
R8: 200 kg (441 lb)]. Lift the module by the upper part using the lifting lugs attached
to the top of the unit. Do not tilt the drive module. The centre of gravity of the unit
is high. The unit will overturn from a tilt of about 6 degrees. An overturning unit
can cause physical injury.
Heatsink
Check the cleanliness of the cabinet and the surroundings. When necessary, clean
the interior of the cabinet with a soft brush and a vacuum cleaner.
The module heatsink fins pick up dust from the cooling air. The drive runs into
overtemperature warnings and faults if the heatsink is not clean. When necessary,
contact ABB for cleaning of the heatsink.
Fan
The lifespan of the cooling fan depends on the drive usage and ambient
temperature. See the appropriate ACS800 firmware manual for the actual signal
which indicates the running time of the cooling fan. For resetting the running time
signal after a fan replacement, please contact ABB.
Replacement fans are available from ABB. Do not use other than ABB specified
spare parts.
