If the certification is supplemented by an X, please note the special conditions in the EC
type examination certificate. Special conditions for explosion-proof machines (Page 17)
● When installing electrical systems in hazardous zones, observe EN/IEC 60079-14 and
the corresponding country regulations.
● The machine temperature class specified on the rating plate must be equal to or greater
than the temperature class of any combustible gases that may develop.
● Select optional mounted equipment according to the requirements of Directive
2014/34/EU.
The rotor is dynamically balanced. For shaft extensions with feather keys, the balancing type
is specified using the following coding on the face of the drive end of the shaft:
● "H" means balancing with a half feather key (standard)
● "F" means balancing with a whole feather key
● "N" means balancing without a featherkey.
Risk of injury due to Incorrect installation or removal
If the required touch protection measures for drive output elements are not observed this
can result in physical injury and material damage.
• The general touch protection measures for drive output elements must be observed.
• Drive output elements may only be pushed on or pulled off with the correct equipment.
• The feather keys are only locked against falling out during shipping. If you commission a
machine without a drive output element, the feather keys must be secured to prevent
them from being thrown out.
The featherkey data on the shaft and transmission element must indicate the correct type of
balancing in each case and must be correctly mounted.
The balancing quality corresponds to vibration severity grade "A" for the complete machine;
vibration severity grade "B" is possible as an option, i.e. in order to ensure the desired
balancing quality, it must be ensured that the featherkey data on the hub and machine shaft
complement each other in the case of a shorter or longer output transmission element.
