2.3 - OPERATING LIMITS AND CONDITIONS
Ambient conditions
•
Operation of gear units is permitted at ambient temperatures between -20°C and +40°C.
However, for temperatures between -20°C and -10°C unit may only start up after it has been progressi-
vely and evenly pre-heated, or otherwise initially operated unloaded.
Load may then be connected to the output shaft when the gear unit has reached the temperature of
-10°C, or higher.
•
Do not use the gear unit, if not explicitly intended for the purpose, in a potentially explosive atmosphere or
where the use of explosion-proof equipment is specified.
•
Lighting
If the unit is to be serviced in a poorly lit area, use additional lamps and ensure that the work is
done in compliance with applicable safety legislation.
•
Noise - Vibration
During operational testing at the Manufacturer’s premises, the acoustic pressure measured under full load at
a distance of 1 m from the unit and 1.6 m above ground level without vibration was less than 85 dB(A).
The vibrations produced by the gear unit do not constitute a health risk for personnel. Excessive vibration
may be the result of a fault and should be immediately reported and eliminated.
Modification of the gearbox configuration or mounting position is only permitted if previously aut-
horised by the BONFIGLIOLI RIDUTTORI technical service.
Failure to obtain said authorisation voids the ATEX certification
.
The nameplate data on the maximum surface temperature, refer to measurements made in nor-
mal ambient and installation conditions. Even minimal variations to said conditions (e.g. smaller
mounting cabinet) could have a significant impact on the build up of heat.
