-  Switch  off  the  power  supply  before  performing  any 

connection operations (connection or disconnection, with or 

without connectors) at the encoder or cabinet end.

-  For  reasons  of  synchronization,  power  up  and  power 

down  the  encoders  and  any  associated  electronic  devices 

simultaneously.  On  the  first  power-up,  check  that  the 

“” terminal is supplying the required voltage before 

connection.

- For the supply, use stabilized power supplies.

Power supplies via transformers providing 5 V (or 24 V) rms, 

followed by rectifiers and smoothing capacitors, must not be 

used, as in reality the resulting DC voltages obtained are:

For 5 V: 5x√2 = 7.07 V

For 24 V: 24x√2 = 33.936 V
