3.1.8 Repairs
Repairs must be carried out by Getriebebau NORD or by an officially recognised expert. The work
must be indicated with an additional repair plate. With the exception of standard, commercially
available and equivalent components, only original spare parts (see spare parts list) may be used. The
particularly applies for seals and connecting components.
For motors with closed condensation outlets, the threads of the closing screws must be coated with
Loctite 242 or Loxeal 82-21 after the condensation has been drained. The closing screws must be re-
inserted immediately. The electrical connections must be checked at regular intervals.
Check that the connection terminals, and the electrical bonding terminal are firmly fastened. Check
that the cable gland and the terminal box gasket are in good condition
All work on electrical machinery must be performed when the machine is at a standstill and with all
poles disconnected from the mains.
The motor must be removed for any measurement of the insulation resistance. The measurement
must not be performed in the explosion hazard area. As soon as measurement has been completed,
discharge the connecting terminals again immediately by shorting them in order to prevent any spark
discharges occurring in the explosive area.

DANGER!
Explosion hazard
Insulation measurements may cause sparks and therefore ignition of an explosive
atmosphere.
• Only perform insulation measurements outside of an explosive atmosphere.
• Discharge the connection terminals by short circuiting them after the measurement and
before returning to an explosive atmosphere.

3.1.9 Painting
The motors are equipped with a suitable, electrostatically tested painting ex-works. Subsequent
painting may only be carried out in consultation with Getriebebau NORD or a repair workshop
approved for the repair of explosion-protected electric motors. The valid standards and regulations
must be observed.
