Description
3.5 nstallation
Other possible fields of application for explosion-proof machines
The type of construction of the machine is stated on the nameplate.
DANGER
In the case of explosion-proof machines where the shaft extensions point downwards
(types of construction IM V5, IM V1 or IM V18 ) a protective top cover is mandatory. A
protective top cover is automatically installed at the factory for explosion-proof motors with
IM V5, IM V1 or IM V18 types of construction. For types of construction with shaft extension
pointing upwards, a suitable cover must be implemented to prevent small parts from falling
into the fan cover (see the standard IEC/EN 60079-0). The cover must not block the cooling
air flow.

3.5.7 Degree of protection
The machines have degree of protection IP 55 (see rating plate). They can be installed in
dusty or humid environments.
NOTICE
Condensation holes
In order to comply with the degree of protection, any existing condensation holes are to be
sealed!
If the machines are used or are stored outdoors, we recommend that they be kept under
some sort of additional cover so that they are not subjected to direct intensive solar radiation,
rain, snow, ice or dust over a long period of time.
In such cases, technical consultation may be appropriate.
The machines are suitable for use in the tropics.
Guide value of 60% relative humidity at a coolant temperature (CT) of 40° C.
Ambient temperature: -20° C to +40° C
Installation altitude: ≤ 1000 m
