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 and perform installation
work within an open casing.
Warning:
Touching voltage-carrying conductors or telephone connections
can cause life-threatening electric shocks.
•
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 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 extension modules.

Also disconnect the devices from additional power sources (e. g. UPS).
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.
