Chapter 7 Repair and Maintenance
 Do not repair or maintain the braking unit at power-on. Fail to comply will result in electric shock.
 Repair or maintain the braking unit only after ensuring that the input bus voltage is lower than 36
VDC, 5 minutes after power-off. Otherwise, residual charge on the capacitor may result in
personal injury.
 Repair or maintenance of the braking unit must be performed only by qualified personnel. Failure
to comply will result in personal injury or device damage.
 Ensure that all screws are fixed after repair or maintenance. It is forbidden to leave tools or
screws inside the braking unit.
 Re-set the parameters after the braking unit is replaced. All the pluggable parts must be plugged
or removed after power-off.
7.1 Routine Maintenance
The influence of the ambient temperature, humidity, dust and vibration will cause the
aging of the components inside the braking unit, which may cause potential faults or
reduce the service life of the braking unit. Therefore, it is necessary to carry out routine
and periodical maintenance.
Routine maintenance involves:
 Whether the installation environment of the braking unit changes
 Whether the cooling fan works properly
 Whether abnormal vibration exists
 Whether braking unit is overheated
Routine cleaning involves:
 Keep the braking unit clean all the time.
 Remove the dust, especially metal powder on the surface of the braking unit, to
prevent the dust from entering the braking unit.
 Clear the oil stain on the cooling fan of the braking unit.
7.2 Periodic Inspection
Perform periodic inspection on the items that are difficult to check during running. Periodic
inspection involves:
 Check and clean the air filter periodically.
 Check whether the screws become loose.
 Check whether the braking unit is corroded.
 Check whether the wiring terminals have arc signs.
 Carry out main circuit insulation test.
Note
Before measuring the insulating resistance with megameter (500 VDC megameter recommended),
disconnect the main circuit from the braking unit. Do not use the insulating resistance meter to test the
insulation of the control circuit. The high voltage test need not be performed again because it has been
completed before delivery.
