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.

qualified electrician to open the casing. Also disconnect the device from additional
power sources (e.g. UPS, if installed).

disconnecting it from the main power supply.
Warning: Power surges, which may occur during electrical storms, can cause life-
threatening electric shocks, or damage or destroy the PBX.
