Forum 523/524
Forum 523/524 is designed to be installed by the user. Live parts
should not be accessible to users or if they are accessible to users,
should be accessible only to a user using the appropriate tool. For
this reason, Forum 523/524 features a special casing mechanism,
which can only be opened step by step.For your own safety,
please read the
Safety Precautions starting on page 32. As with all
highly sensitive electronic devices, static charges can destroy
components in a fraction of a second. For this reason, you should
first pick up your tool then touch an earthed metal object (e.g. a
radiator), before touching any connections or components inside
the device.
CAUTION!
Static charges can damage the electronic components of
the Forum 523/524.
There are no directly accessible circuits operating under danger-
ous voltage on Forum 523/524’s connection panel. You must still
switch off all power to the device when performing any kind of
installation. Pull the plug out of the mains power supply socket.
It is recommend to connect the pressure terminals provided here
as sockets to externally mounted sockets – e.g. UAE sockets for
U
pn
ports, IAE sockets for S
0
ports and standard telephone sock-
ets for a/b ports. You can plug these connecting sockets into ter-
minals and do not have to switch off the device to do this.
