3.6.4 POWER CONNECTION
DANGER
Connecting the device to the power source can only be performed by a qualified
installer in a
voltage-free state.
CAUTION
The supply and communication cables have to be laid into the device and electrical
cabinet through separate cable glands and cord anchorage, which are installed
before the cable terminals. This way we ensure the cable is relieved from strain and
the electrical cabinet is protected from water penetration.
CAUTION
Wrong dimensioning of the power cable or too weak terminal fuses of the device
could lead to an overload of the safety elements on the power grid of the
building which could lead to overheating of the electrical installation. Follow the
requirements listed in this manual.
