1)
Only ES1 and PS1 classified power supplies in accordance with EN 62368-1 may be used to supply the phone. Additionally, only one current
supply may supply the phone. Use either LAN1 or the connections X1.7-X1.8.
2)
The DC power supply must be ground potential free.
3)
The permitted load currents of the output contacts are voltage dependent. Calculate their maximum values as indicated below by generating
the quotient of switching-voltage-dependent switch rating Pswitch(Vswitch) and switching voltage Vswitch. Furthermore, the result must not
exceed the indicated maximum value of the switching current Iswitch.

4)
The electric circuits of the switching contacts of both relays must not be interconnected with different external conductors of an AC network.
5)
The three inputs are active and may only be switched with potential-free contacts.
