Guide module horizontal with the cable frame side
ahead, into the opening of the middle support
columns.

Ensure that the string cable is freely accessible for subsequent
wiring.

Place module on the end supports.

Place module flush between the spacers on the
ground profile.

Press module against the middle support columns if it does
not latch directly into the ground profile.

Place neighbouring module upright on module
longitudinal side (cable frame side).

Wire the modules (a click signals correct wiring).

Insert cabled module into the ground profile without
pulling the cables (see p. 26, work steps 1 and 2).

•

The modules are fastened on the ground profiles
with the end clamp.

Screw end clamps with pre-assembled screw to each ground
profile.

The terminals clamps function as edge and centre terminals.

Optional potential equalisation:

Raise screw and push fork of the long potential
equalisation cable under the screw head.

Tighten screw together with potential equalisation cable and
thus connect the ground profiles electrically.

Insert modules on the opposite side in the same
way and wire.

Insert module and arrange without pulling the cables.

Carry out safety and functional tests, ensuring that
they are state of the art.

NOTE! Damage to the modules!

Make sure that the plug connections are not
located in a water-bearing level.

WARNING! Risk of fire!

Under no circumstances use light concentration
devices (e.g. mirrors or lenses).

Optional step:

Integrate the system into the existing lightning
protection system in accordance with the local
regulations.

Make sure that the wiring is not exposed.

Protect the wiring from dirt, moisture and UV
irradiation.

Do not use chemical cleaning or rotating
brushes.

Only clean the modules manually with sufficient
water.
