9  Installation 

The unit can be mounted as follows: 

  mounting of the distributor on a 35 mm mounting rail according to EN 60715. 

  using M4 screws for wall mounting. (additional screws are not included) 

  make the connection in accordance with the wiring diagram or the nameplate 

 

 

 

 

Switch on the control voltage. 
When the device is ready for operation, the relay must activate, when a current greater than the Ion response 
value flows through one of the current transducers. 
 

 

WARNING! 
Dangerous electrical voltage! 
May cause electric shock and burns. 
Disconnect the system and equipment from the power source before starting any work. 

Caution! 
Only one live wire may be fed through the current transducer! 

Failure-free and safe operation of the equipment requires that it is properly transported and stored, 
professionally installed and commissioned, and operated as intended. 
Work on the unit may only be performed by persons who are familiar with the installation, startup and 
operation of the unit and who have the necessary qualifications for this works. They must comply with the 
operating manual, the instructions placed on the device and the relevant safety regulations for the 
installation and operation of electrical systems. 
The devices are built and tested according to DIN VDE/EN/IEC standards and leave the factory in perfect 
safety condition. 
To maintain this condition, follow the safety instructions in the manual marked "Caution". Failure to follow the 
safety instructions could result in death, personal injury, or property damage to the device itself and to other 
units and equipment. 
If the information in the manual is not sufficient, please contact us directly or your sales agent. 
Instead of the industrial standards and regulations mentioned in the operating manuals and applicable in 
Europe, observe any relevant regulations valid in the country of use, should the device is operated outside 
the above area. 

Install a circuit breaker marked as a isolating device and an overcurrent protection 

device (rated current ≤ 10 A) in the power line near the unit (easily accessible). 

Observe the maximum permissible temperature when installing in the control box. Ensure adequate 
distance from other appliances or heat sources. If cooling is impeded, e.g. by close proximity to equipment 
with a higher surface temperature or hindered cooling air flow, the permissible ambient temperature will be 
reduced. 

Caution 
Before connecting the unit to the mains supply, make sure that the Us control voltage on 
the side rating plate corresponds to the mains voltage connected to the unit!
