WARNING!
Mains connection via mains plug is not permis‐
sible.
The device must not be connected to the mains
using a mains plug. If the socket is incorrectly
wired, there is a risk of the electric safety not being
met due to faulty potentials.
The device may only be connected via a terminal
box.
Lightning and surge protection
We recommend fitting lightning and surge protec‐
tion in the building. The lightning and surge protec‐
tion should consist of protection from high, medium
and low voltage power surges. The operator is
responsible for ensuring that the lightning and
surge protection required is implemented correctly.
The cabling system requires a low voltage cable with a tempera‐
ture resistance of ≧ 70 °C.
Only use the threaded cable connector set supplied with installa‐
tion to guarantee the degree of protection and UL
The device should have no unsealed openings after installation.
1. Manually tighten the threaded cable connector's union
nuts. "Manually tighten" means ➨ tighten as far as possible
without tools.
Ensure that the rubber insert surrounds the cable or closure
cap in a snug manner. There must not be any gaps.
2. Then use an appropriate tool to tighten the union nuts by 90°.
