Installing Cable Between the External S

Warning: Power surges, which can occur during
electrical storms, can cause life-threatening electric
shocks or damage/destroy the PBX.
Let a skilled electrician lay all the cables inside the

in question. See Page
– The distance/line length between the devices
depends on the connection type:
Max. 150 m for a Point-to-Multipoint connection
Max. 1000 mm for a Point-to-Point connection
– Installation cable (for example, J Y (St) Y 2x2x0.6)
with the following characteristics:
4-core
Unscreened; however: screened for unfavourable
conditions, for example, near a strong transmitter
or an electrical power line
Preferably star quad stranding
Note: If you would like to install an external S
with wall sockets, please refer to
