Installation 

The device is only allowed to be installed and operated within the permissible temperature 
range. Please ensure an adequate ventilation and avoid all direct contact between the device 
and hot or aggressive gases and liquids.  

 

Before installation or maintenance, the unit must be disconnected from all voltage-sources. 
Further it must be ensured that no danger can arise by touching the disconnected voltage-
sources. 

 

Devices which are supplied by AC-voltages, must be connected exclusively by switches, 
respectively circuit-breakers with the low voltage network. The switch or circuit-breaker must 
be placed as near as possible to the device and further indicated as separator. 

 

Incoming as well as outgoing wires and wires for extra low voltages (ELV) must be separated 
from dangerous electrical cables (SELV circuits) by using a double resp. increased isolation. 

 

All selected wires and isolations must be conform to the provided voltage- and temperature-
ranges. Further all country- and application-specific standards, which are relevant for structure, 
form and quality of the wires, must be ensured. Indications about the permissible wire cross-
sections for wiring are described in the Technical Specifications (see chapter 7).  

 

Before first start-up it must be ensured that all connections and wires are firmly seated and 
secured in the screw terminals. All (inclusively unused) terminals must be fastened by turning 
the relevant screws clockwise up to the stop.  

 

Overvoltages at the connections must be limited to values in accordance to the overvoltage 
category II.  

 

For placement, wiring, environmental conditions as well as shielding and earthing/grounding of 
the supply lines the general standards of industrial automation industry and the specific shielding 
instructions of the manufacturer are valid. Please find all respective hints and rules on  
www.motrona.com/download.html --> “[General EMC Rules for Wiring, Screening and Earthing]”.

Cleaning, Maintenance and Service Notes 

To clean the front of the unit please use only a slightly damp (not wet!), soft cloth. For the rear 
no cleaning is necessary. For an unscheduled, individual cleaning of the rear the maintenance 
staff or assembler is self-responsible.  

 

During normal operation no maintenance is necessary. In case of unexpected problems, failures 
or malfunctions the device must be shipped for back to the manufacturer for checking, 
adjustment and reparation (if necessary). Unauthorized opening and repairing can have 
negative effects or failures to the protection-measures of the unit.
