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 dur-
ing 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 conduc-
tor. 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 terminals connected
1. Connect the connecting cable to the potential com-
pensation bar of the house installation or the protec-
tive earth conductor.
2. Insert the connecting cable into the casing and con-
nect it to the earth terminal.

Updating or Upgrading the PBX

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-hazard-
ous 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. 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.
Caution: Electrostatic charges can destroy sensitive components.
• Discharge electrostatic charges from yourself before touching the circuit boards
with your hands or any tools. To do this, touch a preferably earthed metal object, such as
the PBX's earthing terminal or a computer case.
