Warning: Improper handling of the device can cause life-threatening elec-
trical shocks.
Warning: Touching live conductors or telephone connections may cause
life-threatening electrical shocks.
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 ter-
minal. See
76
Only qualified electricians should open the casing and perform installa-
tion work within an open casing.
Mount the PBX in the immediate vicinity of an earth wire (potential com-
pensation bar of the house installation or protective earth conductor).
Connect the PBX's earth connection to the earth wire with a connecting
cable whose conductor diameter is at least 2.5 mm
Only a fixed installation is allowed for the connection of the earthing ter-
minal of the PBX to the potential compensation bar of the house instal-
lation or the protective earth conductor. Plug connections are not
allowed.
The PBX contains hazardous voltages, even outside the power supply
unit (for instance ringer voltages). Work on active, contact-hazardous
parts is only permitted after they have been disconnected, and are no
longer live.
Working close to active parts is only permitted if these parts are discon-
nected, and are no longer live, 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 extension module, or switch or connect
equipment.
If necessary, also disconnect the devices from auxiliary power sources
(for example, a UPS), if present.
