Safety Information
Please note the basic safety information below.
Warning: Improper handling of the device can cause life-threatening electric
shocks and can damage or destroy the PBX.
• Only a qualified electrician may open the casing. If necessary, have a specialist
commission the device.
• Only a qualified electrician may perform installation work within an open casing
or service work using the buttons inside the casing. If necessary, commission
a specialist to perform this work.
• Read the instructions for the device and keep them for future reference.
Warning: Touching voltage-carrying conductors or telephone connections can
cause life-threatening electric shocks.
• Mount the PBX close to an earth wire (potential compensation bar of the house
installation or protective earth conductor). Connect the PBX's earth connection
to the earth wire with a connecting line whose conductor diameter is at least
2.5 mm².
• The PBX contains hazardous voltages, even outside the power supply unit (for
instance ringer voltages). Working 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
• Pull out the PBX's power plug before instructing a qualified electrician to open
the casing, to install the expansion modules, or to switch or connect equipment.
• 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.
• If necessary, also disconnect the devices from additional power sources (e. g.
UPS).
• Do not make any structural changes to the device.
• For some installation and maintenance work it is necessary to open the PBX
while it is in operation (qualified electrician only). Make sure that the PBX is
never left unattended while running with an open casing.
• Ensure you comply with the relevant regulations when handling mains voltage
and devices attached to the mains.
• Only operate the device when the casing is closed.
• Only operate the device when it is mounted on a wall (COMpact 5000) or
securely fastened in a 19" rack (COMpact 5000R).
