3.8.10 Maintenance
The voltage must always be switched off and secured against switch-on before opening.
Notice! Temperatures may occur within the motor that are higher than the maximum permissible
surface temperature of the housing. The motor must therefore not be opened in an explosive
dust atmosphere. The motors must be checked and tested for functional safety on a regular
basis. The valid national standards and regulations must be observed.
Impermissibly high dust deposits > 5 mm are to be avoided. The motor must not be further operated if
functional safety is not guaranteed. Upon replacement of the ball bearings, the radial shaft seals must
also be replaced. Please use the radial shaft seals prescribed by Getriebebau NORD. It is essential to
pay attention to professional installation. The radial shaft seal’s outer ring and sealing lip must be
lubricated. If an explosion-protected gear unit is flanged to the motor in a dust-proof manner, a NBR
radial shaft seal may be used on the motor’s A side if the gear oil temperature does not exceed 85°C.
Only original parts may be used as spare parts, except for standardised, customary and equivalent
parts. This is particularly valid for seals and connection parts. In case of terminal box parts or spare
parts for outer earthing, the parts must be ordered according to the spare parts list of the operating
instructions.
Seals, radial shaft seals and cable glands must be checked for functionality on a regular basis.
The maintenance of the motor’s dust protection is of outstanding importance for explosion
protection. Maintenance must be carried out by qualified personnel in a specialist workshop with
appropriate equipment. We urgently recommend that the general overhaul is carried out by the NORD
Service department.
