High-voltage machines are components for installation in machines as defined in the Machinery Directive
2006/42/EC. Commissioning is prohibited until the conformity of the end product with this Directive has been
established (the relevant local safety and installation regulations, e.g. EN 60204, must be observed).
These supplementary operating instructions apply to explosion-proof, surface-cooled electrical machines for
high voltage. The protection class according to IEC/EN 60034-5 for motors used in zones 1, 2 and 22 is a
minimum of IP 55. For use in zone 21, the motors are designed to meet
IP 65 as a minimum. Only electrical machines with the approved type of ignition protection may be used in
hazardous areas.
Electrical machines of equipment group II, category 2 (assigned zones 1 and 21)
or equipment group II, category 3 (assigned zones 2 and 22)
Any other or further use is deemed to be improper.
No liability can be accepted for damage or operational malfunctions resulting from assembly errors, failure to
observe these instructions or improper repairs.
1.5 Potentially explosive atmospheres
Which areas outdoors or in enclosed spaces are to be regarded as potentially explosive within the meaning
of the relevant ordinances and regulations must be determined exclusively by the plant operator or, if there is
any doubt about the definition of potentially explosive atmospheres, by the competent supervisory authority.
The responsibilities of the plant operator are defined in Directive 99/92/EC -
