Safety in case of faults
Ì The operating voltage U
B
 is reverse polarity protected. 
Ì The contacts OA/OB are short circuit proof.
Ì A short circuit between OA and OB is detected by the switch. 
Ì A short circuit in the cable can be excluded by laying the cable with protection. 
Fuse protection for power supply
The power supply must be provided with fuse protection depending on the current 
required for the outputs. The following rules apply:
Max. current consumption of a switch I

Requirements for connection cables
Caution!
Risk of damage to equipment or malfunctions as a result of incorrect connec-
tion cables.
Ì Use connection components and connection cables from EUCHNER
Ì On the usage of other connection components, the requirements in the fol-
lowing table apply. EUCHNER provides no warranty for safe function in case 
of failure to comply with these requirements. 
Ì The connection cable must not be longer than 180 m in total.
Observe the following requirements with respect to the connection cables:
Parameter Value Unit
Wire cross-section min. 0.14 mm²
R max. 150 W/km
C max. 120 nF/km
L max. 0.65 mH/km
Recommended cable type LIYY 8x or 5x0.14 mm²
