Equipment to be switched on/off is to be connected to the connecting cables leading out of cable inlets (vi) and (vii),
which are connected with electromechanical relays, relay 1 (vi) and relay 2 (vii). The changeover contact of both relays can
switch DC and AC current loads in the indicated load range.
The position of the cable inlets can be found in Figure 1 “- Housing top view and position of the wire/cable inlets (i) – (viii)”
on page 8.

Please perform a final check of the mountings and connections to ensure perfect commissioning and safety.
Connect the keyboard (6) via the plug-in connection (7) with the circuit board located in the interior of the housing.
Then secure the used keyboard with the 4 screws (8).
2.5 Concluding work
The external DC power supply is to be connected to terminals 7 and 8 of the terminal strip X located in the terminal
compartment.
Make sure that you use sufficient conductor cross-sections so that the minimum required DC voltage is available on the
terminals. You can find more information about this in the technical data section of this user manual.

Attention!
- Only ES1 and PS1 classified power supplies in accordance with EN 62368-1 may be used to supply the phone.
- If you supply the phone via connectors X1.7 and X1.8, your LAN1 connecting cable must not conduct any PoE supply (Power over
Ethernet).
Attention!
- 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.
