8.1.1 Installation 
recommendations 
Mains voltage lines  
(mains connection, burners, pumps, servo motors): 
Diameter 1.5 
mm
2
 
Max. permissible length 
No limit for installation in buildings. 
Safety low-voltage lines  
(sensors, ext. switches upon demand via switching contact, modem connection lines, analog 
signal lines etc.) 
Diameter 0.5 
mm
2
 
Max. permissible length 
100 m (looped circuit); longer connection lines should be avoided 
to prevent the risk of interference
