General information
Operating manual for INVEOR α | DOC01539818 - 0004 | 2017-01 | V2.0 EN 21
1.9.6 Maintenance and inspection
The drive controllers may only be maintained and inspected by electricians with recognised
training. Unless explicitly described in this operating manual, changes to hardware and software
may only be undertaken by KOSTAL experts or persons authorised by KOSTAL.
Cleaning the drive controllers
Drive controllers are maintenance-free if operated as intended. If the air contains dust, the cooling
fins of the motor and drive controller have to be cleaned regularly.
Measurement of insulation resistance on control part
An insulation test on the control card's input terminals is not permitted.
Measurement of insulation resistance on power part
The power part of an INVEOR α is tested with 2.02 kV in the course of series testing.
Should the insulation resistance have to be measured during a system test, this can be done under
the following conditions:
an insulation test can be undertaken for the power part alone,
to avoid excessively high voltages, all the INVEOR α's connection cables must be
disconnected before testing,
a 500 V DC insulation tester should be used.
