7 Grounding
Particularly in exposed locations, sufficient lightning
protection is recommended. Integration into existing
lightning-protection systems must occur in observance
of current country-specific norms and regulations. The
respective drill holes for grounding are marked on the
reverse side of the module frame.
Please perform the following grounding measures:
Important Notice!
Attachment of a fitting ring-cable socket (cable cross-
section: min. 2.1 mm²).
Use of a fitting fastening screw (minimum diameter:
4 mm), a self-cutting serrated washer, a spring
washer and the fitting nut.
Use of a fitting self-cutting screw. Two complete
thread turns of a screw must interlock with the
metal.
Damaging contact corrosion can be avoided by using
corrosion-resistant materials.
Position of the grounding drill holes in accordance
with Illustrations 3 – 6.
8 Maintenance and upkeep
Minimal maintenance and upkeep effort is required in
order to maintain the optimum output of the solar mod-
ule. In the interest of optimum system output, we rec-
ommend to inspect and/or work through the following
items on a semiannual cycle:
Bosch Solar Module c-Si M 48 EU I Bosch Solar Module c-Si M 60 EU I Bosch Solar Module c-Si M 60 S EU I Bosch Solar Module c-Si P 60 EU Bosch Solar Energy AG
In the event of heavy or localized contamination (e. g.
with bird droppings), it is recommended to clean the
glass surface of the module with limefree water
which matches the module temperature and a soft
brush. No aggressive cleaning agents, acids or
leaches may be used.
The electrical and mechanical connectors must be
checked for cleanliness, durability and sound conditi-
on. Any irregularities must be remedied immediately.
Regular verification of the yields by the operator is
recommended.
9 Disposal
Defective or old solar modules must be appropriately
disposed of. These may not be disposed of in house-
hold waste.
