Safety instructions and references for putting into operation 

 

Attention! 
Safety Instructions and references 
please read carefully! 

 

15.1 Explosive atmospheres 

  The increased danger within explosive atmospheres (gas or dust) requires the careful attention of the 

safety instructions and references for putting into operation. Observe the national safety rules and 
regulations for prevention of accidents as well as the standard EN 60079-14 / VDE 0165-1. All work 
for the connection, for putting into operation and maintenance is to be implemented by qualified, 
responsible technical personnel. Inappropriate behaviour can cause heavy personal damage and 
damages to property. 

  The response of the device must directly switch off the motor, also when used together with 

inverters. This must be implemented with circuitry. 

 

15.2 Special remarks for explosive gas atmospheres areas (Zone 0, 1 and 2) 

  The device must be installed outside potentially explosive gas atmospheres unless the device is 

protected by a suitable ignition protection type (for example a flameproof enclosure). 

 

15.3 Special remarks for use in the presence of combustible dust (Zone 20, 21 and 22) 

  The device must be installed outside potentially explosive dust atmospheres unless the device is 

protected by a suitable enclosure for dust atmospheres.
