WARNING

Ensure the proper connection of the L phase conductor and N
neutral conductor if you are using easy-AS devices with a power
supply greater than 24 V AC!
If the L phase conductor and N neutral conductor connections
are reversed, the full connection voltage of the L phase
conductor (100 to 240 V AC) is present on the serial multi-
function interface.
Improper connection on the multi-function interface or the
insertion of conductive objects in the shaft may cause fatal
electric shock.
For your safety:
• Use the original programming cable, which ensures safe
electrical isolation of the PC terminal from the connection
voltage of the L phase conductor (100 to 240 V AC).
Press the interface cover back onto the shaft if you no longer
need the interface.
CAUTION
A short current surge will be produced when switching on for
the first time. Do not switch on easy with reed contacts
because these could possibly burn or stick.
