32
This section describes the preparations required before installing and commissioning the device. In addition, information is
provided on how to open the casing, make changes and mount it in a rack as well as how to upgrade the PBX with modules (not
included in the delivery).
In addition, information is given on how to close the casing again after installation work has been completed.
Overviews of base circuit board as well as the connection areas on the front panel should facilitate finding the various connection
options.
Opening the Casing
Warning: Improper handling of the device can result
in life-threatening electrical shock.
씮
Only a skilled electrician may open the casing and
perform installation work within an open casing.
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
Pull out the power plug of the PBX before com-
missioning a skilled electrician to open the casing
to install the expansion module or perform swit-
ching or connecting services.
씮
If available, also disconnect the devices from
auxiliary power sources (for example, UPS).
Warning: Power surges, which can occur during
electrical storms, can cause life-threatening electric
shocks.
씮
Therefore, do not mount the PBX during an
electrical storm. Avoid disconnecting and
connecting lines during an electrical storm.
