2.2 CONFORMITY
All gearboxes or gearmotors (when supplied with motor) are designed as state of the art devices
in compliance with the provisions of applicable Essential Health and Safety Requirements.
All gearmotor motors conform to the provisions of the Low Voltage Directive 2006/95/EC and the
Electromagnetic Compatibility Directive 2004/108/EC.
Furthermore, if specied for use in potentially explosive atmospheres, the gear units are de-
signed and constructed to conform with the Essential Health and Safety Requirements (EHSR)
of Annex II of the ATEX Directive 2014/34/EU and conform to the following classication:
• Equipment group: II.
• Category: Gas 2G - Dust 2D.
• Zone: Gas 1 - Dust 21.
• Temperature class: T4 for 2G and 135°C for 2D.
2.3 OPERATING LIMITS AND CONDITIONS
Modication of the motor execution or mounting position is only permitted if previously authorised
by BONFIGLIOLI RIDUTTORI’s Technical Service.
Failure to obtain said authorisation renders the ATEX certication null and void.
Ambient conditions
• Do not use the gear unit, if not explicitly intended for the purpose, in a potentially explosive at-
mosphere or where the use of explosion-proof equipment is specied.
The nameplate specications regarding the maximum surface temperature, refer to readings tak-
en in normal ambient and installation conditions.
Even minimal variations to said conditions (e.g. smaller mounting cabinet) may have a signicant
effect on the unit’s heat output.
• 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 the safety requirements of established legislation.
