Important Information

This section includes necessary information for operating the devices safely. Before installing and commissioning the PBX, be
sure to read the safety information listed here. Also become familiar with the proper use of the device as well as the technical data.
Safety Information
Warning: Improper handling of the device can result
in life-threatening electrical shock.
씮
Only a skilled electrician may open the casing. If
necessary, have an authorised dealer
commission the device.
씮
Only a skilled electrician may perform installation
work within an open casing or service work using
the buttons inside the casing. If necessary,
commission an authorised dealer to perform this
work.
씮
Mount the PBX in the immediate vicinity of an
earth wire (potential compensation bar of the
house installation). Connect the earth connection
of the PBX to the earth wire via a connecting cable
with at least 2.5 mm².
Warning: Touching voltage-carrying conductors or
telephone connections may cause a life-threatening
electric shock.
씮
The PBX contains hazardous voltages, even out-
side of the power supply unit (for instance ringer
voltages). Work on active, contact-hazardous
parts is only permitted after creating a voltage-
free state.
Working close to active parts is only permitted if
these parts are voltage-free or are protected
against direct contact.
씮
Casing variants for wall mounting: Pull out the
power plug of the PBX before commissioning a
skilled electrician to open the casing to install the
expansion module or perform switching or con-
necting services.
씮
19" casing variants: The Power button switches
the voltage at the module expansion slots and on
the main circuit board off. If the system is switched
off, a skilled electrician can be commissioned to
replace or install expansion modules.
When installing or replacing a module, only touch
the fixing components of the front plate where
necessary. Do not insert any electrically conduc-
tive objects into the casing, since hazardous vol-
tages continue to apply in the power supply unit of
the system.
씮
Remove any voltage from the device by
discharging any capacitors present, if necessary.
In the case of a malfunction, the electrolytic
capacitor for the switch-mode power supply can
remain charged for a long time even after being
turned off.
씮
If available, also disconnect the devices from
auxiliary power sources (for example, UPS).
씮
Do not make any structural changes to the device.
씮
Only mount the components (for example,
expansion modules) in a voltage-free state.
씮
For some installation and maintenance work, it is
necessary to open the PBX while it is in operation
(skilled electrician only). Make sure that the PBX
is never left unattended while working with an
open casing.
씮
Be sure to follow the relevant regulations when
handling 230 V system voltage and devices
attached to the mains.
씮
Only operate the device when the casing is
closed.
씮
Only operate the device when it is mounted on the
wall (casing variants for wall mounting) or
securely fastened in a 19" rack (19" casing
variants).
Warning: Liquid penetrating the casing may cause a
life-threatening electric shock and can damage or
destroy the PBX.
씮
Only operate PBX in closed, dry rooms.
씮
Only clean the device with a soft moist cloth or
anti-static cloth.
Warning: Damaged connection lines as well as
damage to the casing and to the PBX can cause life-
threatening electrical shocks.
씮
Only connect the device connection cable with
sockets that are designed for that purpose.
씮
Make sure that the Schuko socket for connecting
the PBX is properly connected (according to VDE
0100). The power socket must be located near the
PBX and be freely accessible at all times.
씮
Replace damaged connection lines immediately.
씮
Use original components and original spare parts
only.
씮
Always have a professional carry out repairs
immediately. Please contact your skilled
electrician or the manufacturer directly.
Warning: Power surges, which can occur during
electrical storms, can cause life-threatening electric
shocks and may damage or destroy the PBX.
씮
Therefore, do not mount the PBX during an
electrical storm. Avoid disconnecting and
connecting lines during an electrical storm.
씮
Let a skilled electrician lay all the cables inside the
building – including the cable to the door terminal
system.
씮
Protect the devices by installing overvoltage
protection.
Caution: Unauthorised changes to the device can
damage the PBX or breach security and EMC regula-
tions. If security-relevant radio services are disturbed,
the Federal Network Agency can order decommis-
