4.3 Storage
Make sure that in case of long-term storage the following
conditions are met:
– Ambient temperature: -25 °C to +40 °C
– Relative humidity: 0 % to 50 %
ATTENTION
Material damage!
The combiner box must be stored lying flat on the rear
side. Otherwise the cable glands and connectors at the
bottom of the enclosure can be damaged.
In the event that after the storage there is any ingress of
dirt, pollutants or liquid into the equipment, or the formation
of condensation, damage or any other failures the equip-
ment must not be commissioned until the correct remedial
procedure has been discussed with and approved by
Weidmüller.
4.4 Establishing connections
ATTENTION
Material damage!
The tension of the cables can cause mechanical stress to
the enclosure. For this reason, depending on the instal-
lation height, a strain relief underneath the combiner box
may be needed. Regard the national regulations.
– Use only electrical solar cables rated for the voltages,
currents and environmental conditions (temperature, UV,
etc.) expected at the installation site.
– Ensure that you lay all cables with short-circuit protec-
tion and ground fault protection.
– As feeders use only single-core cables with double or
reinforced insulation in accordance with IEC 60364-5-
52.
– To ensure short-circuit-proof and ground-fault-proof in-
stallation in accordance with IEC 60364-5-52, the follow-
ing requirements must be fulfilled:
– Cables must not be installed in the proximity of com-
bustible materials.
– Cables must be accessible.
– Cables must be protected against mechanical dam-
age.
– Do not lay the wires over sharp edges.
