Auerswald COMmander 6000RX Betriebsanleitung Seite 39

• COMmander 6000: 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.
• COMmander 6000R/RX: The Power button switches the voltage at the module expansion
slots and on the main circuit board off. If the system is switched off, a qualified electrician
can be commissioned to replace or install expansion modules. When installing or replacing
a module, only touch the fixing components of the front plate where necessary. Do not
insert any electrically conductive objects into the casing, since hazardous voltages
continue to apply in the power supply unit of the system.
• COMmander 6000R: When commissioning a qualified electrician to upgrade a
COMmander 6000R PBX with the COMmander 6000R Xtension extension set, the power
plug must be unplugged by all means before starting the assembly. It does not suffice to
push the Power button. Only mount the components in a voltage-free state.
• 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 (exception: COMmander 6000R
Xtension).
• COMmander 6000R: After having a COMmander 6000R with the COMmander 6000R
Xtension extension set upgraded by a qualified electrician, the safety of the device has to
be checked according to DGUV A3.
• 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 (COMmander 6000) or securely
fastened in a 19" rack (COMmander 6000R/RX).
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.
