• Mount the PBX close to 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
• Pull out the PBX's power plug before instructing a qualified electrician to open the casing,
to install the expansion modules, or to switch or connect equipment. Also disconnect the
device from additional power sources (e. g. a UPS, if installed).
• Wait for the discharge of any capacitor in the device after disconnecting it from the main
power supply. The electrolytic capacitors in the switch-mode power supply and the ringer
voltage circuitry can remain charged for a long time.
• Do not make any structural changes to the device.
• For some installation and maintenance work it is necessary to open the PBX while it is
in operation (qualified electrician only). Make sure that the PBX is never left unattended
while running with an open casing.
• Ensure you comply with the relevant regulations when handling mains voltage and
devices attached to the mains.
• Only operate the device when the casing is closed.
• Only operate the device when it is mounted on the wall (COMpact 5200) or securely
fastened in a 19" rack (COMpact 5200R, COMpact 5500R).
Warning: Liquid that penetrates the casing can cause life-threatening electric
shocks and can damage or destroy the PBX.
• Only operate the PBX in closed, dry rooms.
• Only clean the device with a slightly damp cloth or an anti-static cloth.
• When cleaning the casing, make sure that no liquid enters the casing.
Warning: Damaged connection lines, or damage to the casing, or the PBX, can
cause life-threatening electric shocks.
• Do not put a damaged PBX into operation.
Warning: Power surges, which can occur during electrical storms, can cause life-
threatening electric shocks and can damage or destroy the PBX.
• Do not touch the PBX or any devices connected to it during an electrical storm.
• Hire a qualified electrician to lay the cables within the building – including the cable to
the door terminal.
• Protect the devices by installing overvoltage protection.
Caution: Unauthorised changes to the device can damage the PBX or breach
security and EMC regulations. If security-relevant radio services are disrupted, the
Federal Network Agency can order the decommissioning of the device in
accordance with §14, section 6, Electromagnetic Compatibility Act.
