WARNING
Risk of electric shock through contact with live wires
An electric shock can be life-threatening or lead to serious injuries such as burns.
There are additional dangers even when working with low voltage and large cable
cross-sections. Cables with a large cross-section generally have lower voltages, al-
though the amperages are higher.
●
Before starting any work, check that the circuits involved are de-energized. Nev-
er take it for granted that turning off a main switch or circuit breaker will reliably
interrupt all circuits.
●
Only use systems, tools, and equipment which are in perfect condition. Do not
use equipment with visible damage.
●
Replace any damaged safety equipment (covers, labels and ground wires) im-
mediately.
●
Replace the power cable immediately if you notice any damage.
●
Only place systems or devices in protection class I into operation using a ground
contact socket.
●
Connect the communication system and, if necessary, the main distribution
frame to the ground wire before starting up the system and connecting tele-
phones and lines. Never operate the communication system without the re-
quired ground wire.
●
Never touch live wires without ensuring adequate insulation.
●
Do not carry out any hardware installation work on telecommunication systems
and devices during a storm.
●
Expect leakage current from the telecommunications network. Disconnect all
telecommunication lines from the system before disconnecting the prescribed
ground wire from the system.
