Warning. Touching voltage-carrying conductors or
telephone connections may cause a life-threatening
electric shock.
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.
Pull out the power plug of the PBX before com-
missioning a skilled electrician to open the casing
to perform switching or connecting services.
If available, also disconnect the devices from
auxiliary power sources (for example, UPS).
Steps to Take
•
Connect the earthing terminal on the main cirnuit
board of the PBX via the connecting cable to the po-
tential compensation bar of the house installation or
the protective earth conductor. See
