Connecting the Earthing
Warning: Touching voltage-carrying conductors or telephone connections can cause
life-threatening electric shocks. The PBX contains hazardous voltages, even outside
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.
• Disconnect terminal devices from the PBX. No terminal devices should be connected
during the installation of the earthing. Connected terminals may feed-in currents which
might cause electrical shocks.
• Pull out the PBX's power plug. Also disconnect the device from additional power sources
(e. g. UPS, if installed).
• Wait at least 3 minutes for the discharge of any capacitor in the device after disconnecting
it from the main power supply.
• Only a fixed installation is allowed for the connection of the earthing terminal of the PBX
to the potential compensation bar of the house installation or the protective earth
conductor. Plug connections are not allowed.
Requirements:
• Screw driver
• Connecting cable with at least 2.5 mm
• Proper earth connection close to the installation site (equipotential bonding rail of the
house installation or protective earth conductor)
• No terminal devices connected
1.
Connect the connecting cable to the potential
compensation bar of the house installation or the
protective earth conductor.
2.
Insert the connecting cable into the casing and
connect it to the earth terminal.
Updating or Upgrading the PBX
