!
To supply the mains voltage (230 V
AC
/ 120 V
AC
) for the power contacts, it is essential to use
a power feed terminal that is designed for 230 V
AC
/ 120 V
AC
(e.g.: KL9150, KL9160,
KL9250, KL9260)!
Bus Couplers, Bus Terminal controllers and power feed terminals for 24 V are not suitable
for the supply of mains voltage into the power contacts!
They are specifically designed for voltages up to 24 V and would be destroyed if
230 V
AC
/ 120 V
AC
was applied to their power contacts!
