Creating equipotential bonding
A lack of equipotential bonding can, in cases of damage, mean that parts
of the U support system may be energised. If contact creates a conduct-
ive connection, this can lead to fatal injuries.
– Creating equipotential bonding.
The equipotential bonding is created on the cable tray or cable ladder
mounted on the support structure.

Maintenance of U support systems
The stability and function of the U support systems can be impaired by
external influences, such as damage or machine vibrations.
Tighten loose connection elements and, if necessary, apply a screw lock
using nuts with an internal plastic ring or a screw locking adhesive. Re-
place damaged parts. Check regularly to see if the connection to the
overall equipotential bonding is still intact.
