Specific Conditions of Use:
• Provision shall be made to prevent the rated voltage being exceeded by
the transient disturbances of more than 140% of the peak rated voltage.
• The equipment must be installed only for use in locations providing
adequate protection against the entry of solid foreign objects or water
capable of impairing safety.
• Only permanently wired cables may enter the cable glands. The user
shall provide for the required strain relief.
• Degree of protection will be safeguarded only when sealing and cable
entry fittings are properly fitted. To ensure proper protection, all wiring
connections and conduit passageways must have the appropriate ATEX/
IECEx certified plug or cable gland.
• Cable Glands shall be mounted into the enclosure in such a way that
they are mechanically protected against impact force.
• To avoid the buildup of electrostatic charge, regularly clean the unit with
a damp cloth.
• The appliance is not to be used by persons (including children) with
reduced physical, sensory or mental capabilities, or lack of experience
and knowledge, unless they have been given supervision or instruction.
Children to be supervised not to play with the appliance.
• The enclosure with a coating must not be used in areas affected by
charge-producing processes, mechanical friction and separation
process, electron emission (e.g. in the vicinity of electrostatic coating
equipment), and pneumatically conveyed dust.
