5 Inspection and maintenance
Working on the electric motor:
Work must not be carried out on the electric motor until the motor has come to a
standstill, is de-energized, depressurised and has cooled. All connections, such as
screw connections, that were loosened must be tightened again after the inspection
or maintenance work.
When carrying out work on the motor, please observe the technical instructions and
notes in the respective Sections in these Commissioning and Manitenance
Instructions.
When carrying out maintenance work, observe all safety instructions which also apply
for the commissioning of the motor (comp. Section 4.1).
Attention!:
If the optional holding brake is fitted, this brake must not perform a safety function
during work on the motor (e. g. retaining loads)!
5.1 Inspection
Depending on the pollution severity on site, cleaning will have to be carried out regularly to
guarantee the continuous dissipation of heat loss. The flow rate and the pressure ratio of the
cooling system must be checked.
If an optional brake is fitted, wear limits are specified (e. g., maximum permissible operating air
gap, maximum number of emergency braking operations). The actual degree of wear on the brake
must be checked at regular intervals. When the permissible wear limits have been reached, the
brake must be replaced (see Section 5.2).
