29
Do not install the Forum 5004/5008/5012 communications system during
a thunderstorm. Do not connect and disconnect lines during a thunderstorm.
CAUTION!
Static charges can damage the Forum 5004/
5008/5012 communications system electronic
components. Please make sure that you discharge
yourself and your tools before and during any installation
work on the Forum 5004/5008/5012 communications
system.
Connection to the mains power supply
The Forum 5004/5008/5012 communications system may only be plugged
into mains power sockets which have a protective earth conductor.
Please note:
Each hardware unit of the Forum 5004/5008/5012 communi-
cations system always requires its own additional earthing. This
is the only way to ensure that dangerous residual currents from
modern switching power supplies are dissipated from the
connected terminals.
Recommendation
: Connect the Forum 5004/5008/5012 communications
system to a separate 230 V power circuit. Then possible short circuits
occurring in other devices do not put the Forum 5004/5008/5012
communications system out of operation. The mains power connection must
be installed by a licenced electrician to avoid danger to people or materials!
DANGER!
Dangerous voltage in device! You may not open the
housing yourself. Pull the plug out of the power socket
before opening the service panel and connecting any
lines/terminals! Failure to do so may cause danger to life
from electric shock!
The Forum 5004/5008/5012 communications system does not have its
own power supply switch. To disconnect the Forum 5004/5008/5012
communications system from the mains power supply, pull the plug out of the
power socket.
