connected and must not be corroded
2)
There must not be any deformations on the housing, color lenses, fixations and
installation spots (ceiling, suspension, trussing)
3)
Mechanically moved parts must not show any traces of wear and must not rotate
with unbalances

The electric power supply cables must not show any damage, material fatigue or
sediments
Further instructions depending on the installation spot and usage have to be adhered
by a skilled installer and any safety problems have to be removed
