After changing the PROFIBUS DP address, you must switch the electronic/encoder power supply 1L+ off and on. The
new PROFIBUS DP address is applied when you switch on.
The green LED DC24V is lit when the 2L+ load voltage supply is connected. If the LED is not
lit, check to see if the power supply is switched on and the fuse is functioning.
