Installation
Warning: Touching voltage-carrying conductors or telephone connections can cause
life-threatening electric shocks. The PBX contains hazardous voltages, even outside
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 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. 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.
Important: Improper use can cause, for example, functional restrictions or interference, the
destruction of the device or, in a worst-case scenario, personal injury.
Only connect equipment that is compatible with the proper use of the PBX.
Installation Instructions
The PBX is intended to be operated in closed rooms. In addition, all of the devices connected
to the system must be located inside the building.
The PBX enables you to connect some devices directly, inasmuch as they are close enough
to the PBX. The distance depends on the length of the equipment connection cables up to a
maximum of 10 m.
If no suitable connection sockets are available or are too far away, you must lay the
installation cable permanently. Use installation cable (e. g. J-Y(St)Y 2x2x0.6) with the
following characteristics:
• Unscreened; however: screened for unfavourable conditions, for example, near a strong
transmitter or an electrical power line
• only for ISDN: preferably star quad stranding
ISDN: When assigning the individual wires, orientate yourself with the identifiers
subsequently listed or refer to VDE 0815 when identifiers deviate.
