Opening the Casing
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
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.
• Disconnect the power plug of the PBX and the accessories before instructing a qualified
electrician to open the casing. 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.
• Only operate the device when the casing is closed.
• Only operate the device mounted on the wall.
Warning: Power surges, which may occur during electrical storms, can cause life-
threatening electric shocks, or damage or destroy the PBX.
• Do not touch the PBX or any devices connected to it during an electrical storm.
1. Unlatch both locks simultaneously by
compressing each with thumb and
index finger.
2. Lift the cover
completely from the casing.
Wall-Mounting the PBX
Warning: Touching voltage-carrying conductors or telephone connections can cause
life-threatening electric shocks.
• Mount the PBX close of an earth wire (potential compensation 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
Warning: Liquid entering the casing can cause life-threatening electric shocks or
damage or destroy the PBX.
