The system should basically be considered intrinsically safe: If the system detects an overtemperature
fault, it will report a system error and remain blocked until it is in the permissible temperature range again.

Busbar system for power supply
The busbar system has several disadvantages:
•
The impedance of the supply cable is decisively influenced by the length of the busbar. For example,
busbars with a length of 50 m provide a supply cable over 50 m.
•
The length of the supply cable to the busbar inside the building must be taken into consideration.
Particularly if the supply cable is only connected to the busbar on one side, the impedance is defined
by the length of the busbar and the supply cable.
•
As the attachments are flexible, potential equalization may not be available on site.
•
Interferences affecting the tightening system, e.g. via the spindle line, cannot be dispersed due to the
high impedance of the protective conductor and the mains lines. They may lead to interferences in
the electronic system.
•
Connection via the rollers to the steel beam system is not possible as the rollers often consist of
plastic.

CAUTION
Risk of damage to persons and property!
Dangerous shock currents due to insufficient PE wire connections!
Protective conductor connections may not be affected by mechanical, chemical, or
electrochemical influences. The connection must be permanent.
