Safety Instructions / Important Information
In addition to the general operating instructions for compressed air motors, the following
regulations apply to explosion protected compressed air motors.
Safety instructions before starting up
– The air motor may only be used / operated in the group II and category 2, Zone1 and 2 (medium G)
or zone21 and 22 (medium GD) which is engraved on the motor.
– The motor may not be opened or changed in any way at all
– Please take note of the conformity certification
– Please read the operating instructions carefully and thoroughly and follow precisely whilst
operating the device.
– Check whether differences in potential are possible due to the motor being fitted. If this is
the case, a conductive connection must be made to equalize the potential.
– Check whether the data engraved on the motor is correct / permitted for the area in which
the motor is to be used.
– We shall not be liable for damage which has occurred because the operating instructions
of the explosion protection motor have not been complied with.
Safety instructions for medium dust (D)
– Due to the over pressure within the air motor, we cannot with reasonable certainty exclude the
possibility that air is leaking at the housing or shaft of the air motor. In case of air leakage the areas
have to be cleaned regularly if necessary to avoid a dust layer or cloud.
– The air motor must be checked and cleaned regularly to avoid a dust layer which is thicker than 2 mm.
– The exhaust air must be removed with a pipe or hose system to avoid dust clouds.
Installation
The air motor is used to produce a rotary movement in industrial machines.
The air motor must only be used according to the technical documentation and
engraving on the housing on the motor.
– The compressed air motor may only be operated at a maximum working pressure of 6 bar.
The air motors can be operated at a pressure below 6 bar at any time.
– Check that there is no inadmissible heat exerted the air motor (e.g. couplings) and that the air motor
is vented properly. Only power transmission according to the Directives 2014/34/EU must be used.
– The temperature of the compress air must not exceed the maximum ambient temperature range.
– The air motor must not be driven against it’s normal rotating direction which is given by the incoming
air due to an external torque applied to it.
– Open in or outgoing air connections must be closed by using a silencer. If a hose is connected to the
exhaust, the hose must also be closed by a sintered silencer or led to an area which is not potentially
explosive.
