4 Wiring
"
Caution!
Before wiring, please compare the supply voltage with the information specified on the nameplate.
If safe operation is no longer possible (e.g. visible damage) please take the device out of service and
secure it against unintentional start-up. Category II overvoltage protection is integrated into the
system. If requirements are tighter, additional overvoltage protection equipment must be installed.
To this end, the connection compartment contains a top-hat rail. Please provide a suitable switch
or circuit breaker when installing in a building. An overcurrent protection device (nominal current
I=10 A) is required for the power cable. The protective earth connection must be made before all
other connections. Any interruption in the protective earth can cause danger.
4.1 Quick wiring guide
4.1.1 Cable laying
• Lay the cable so that it is protected behind the rear panel of the device.
• Use cable ties to keep the cables out of the way.
• You should plan a cable length of approx. 1.7 m between the foundation to the terminal
connection.
4.1.2 Cable types
• Power supply: e.g. NYY-J; 3-core; 1.5 to 2.5 mm
