SAFETY INSTRUCTIONS 

 

 

Please take care of the following basic safety procedures when mounting, starting up or operating this 

equipment:  

 

Read this operating manual before starting up and use of the equipment. The information and warnings given in 

this operating manual must be heeded.   

 

Any work on electrical equipment is only to be carried out by trained specialists as per the regulations currently in 

force.  

 

Attention must be paid to the requirements of VDE 0100 (IEC 364) when setting high-power electrical units with 

nominal voltages of up to 1000 V, together with the associated standards and stipulations.  

 

Check the details on the type plate to ensure that the equipment is connected to the correct mains voltage.  

 

Protection against touching dangerously high electrical voltages:  

Before opening the equipment, it must be switched off and hold no voltages. This also applies to any external 

control circuits that are connected.  

 

The device is only to be used within the permitted range of temperatures and pressures.  

 

Check that the location is weather-protected. It should not be subject to either direct rain or moisture.  

 

The temperature controllers 70304 and 70304.2 must not be used in hazardous areas.   

 

Installation, maintenance, monitoring and any repairs may only be done by authorized personnel with respect to 

the relevant stipulations.
