Mains connection (230VAC)
·
Ensure that the electrical installation (grounding outlet) for the unit (and for additional devices
where required) is installed by a qualified electrician to prevent personal and material risks!
·
Connect any operational grounding provided for your device before connecting the device to the
mains power supply.
·
Unplug the connector before removing the cover and working on the cable terminal bay. Replace
the cover before reconnecting the mains connector.
·
As your PABX system is equipped with a functional grounding connection, a »ground« (waterpi-
pe, heating system pipe or an earth bonding conductor for the house wiring system) should be lo-
cated near the installation location of the system. This connection is required for use of overload
protection modules (FSM). The connection to the PABX must be made with a connecting lead of
at least 2.5 mm

.
·
If you use terminal devices that are linked with the PABX system via USB or RS232, you must in-
stall the functional grounding, as otherwise »hum loops« may be produced.
·
Where at all possible, provide a separate power circuit for the 230 V AC connection of your PABX
system. This protects your PABX from short-circuits that may occur in other in-house equip
-
ment.
·
We recommend installing an overload protection to protect your PABX against surge that can so
-
metimes occur during thunderstorms. For further information please contact your local electrici
