8.13 Intelligent power management
The system features »intelligent power management«, protecting it from overload on internal connections. In case of
overload or a short circuit in the system, current to terminals is interrupted at the modules. The green ready-
for-operation display begins to blink. At intervals of ca. one second, the system attempts to restore power until the
overload cause (e.g. short circuit of several connections) is removed.

Plugs
The FSM module is designed for surge diversion to analogue or S
0
connection lines. Surge protection is required for
each interface to be protected. Surges arising on the lines are discharged to the functional earth. Hence, you must
imperatively install and connect the functional earth (min. 2.5 mm
2
wire), as protection is otherwise not present. The
FSM module is plugged into the matching slots of the connection modules. The FSM is symmetrical in structure. It
can be inserted in any direction.
The FSM is a one-time fuse, meaning that once a module has been removed, it must be replaced with a new modu-
le.
If a surge protection module is actuated by an overvoltage, this cause a short-circuit in the connection lines. If there
is no tone when the receiver is picked up, the module should be checked. Before checking, disable the connection
and the 230 V ~ power supply to the system.
Achtung
If the system is operated in a complex electromagnetic environment (e.g. at locations with machines,
lifts, printers, etc.), every connected interface must be protected via the surge protection module
(FSM). Here again, it is imperative that a functional earth is connected to the system.
