3.2.6. Surge Arrester

There is also the option of installing a surge arrester in the supply variant with mains connection. A viewing window indicates

whether an overvoltage has occurred:

Normal (green) Overvoltage (red)

Even with defective surge arresters, the mains voltage supply of the parking machine is not interrupted. In the

course of regular maintenance work, the surge arresters should therefore be visually inspected, especially after

thunderstorms. Defective surge arresters no longer have a surge protection function and must be replaced.

The surge arresters may only be replaced if the mains voltage line has been de-energised by an authorised

electrician.

3.2.7. Installation Instructions for External Solar Supply

1. Insulate the two connecting cables (2 x 2.5 mm²) and insert them into the empty conduit and conduit post.

2. Screw the solar module onto the solar bracket.

3. Place solar module with solar bracket completely on tubular post. At the same time, the connecting lines must be pulled

back from the PA supply room. Align the solar bracket with the solar module for optimum solar yield, screw it onto the

tubular post and secure it with the pin.

The full charging capacity is only achieved by best sunlight! If installation facing south is not possible, the

necessary charging of the batteries is not guaranteed. The possible obstruction of sunlight by trees, houses,

narrow street canyons, etc. must also be checked on a case-by-case basis.

4. The connecting lines of the solar module are to be connected to the solar controller according to the plan below.
