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-
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. 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.
