3.1.4 Mounting suspension
To attach the logger to a rope or chain, a suitable shackle is provided whose
bolt fits through the cross hole in the cap. As an alternative, you can screw
some different sling gear into the M6 threaded hole at the cap end (e.g. M6
eye bolt).
Corrosion
protection
In water, metal (e.g. zinc-plated) parts of the mounting suspension such as
thimbles, shackles or swivel connectors create voltages (chemically caused
according to the electrochemical series), which can cause corrosion of the
stainless steel of the logger or the above mentioned suspension parts.
Lightning
protection
Electrically conductive ropes or chains harbor the danger of the logger being
damaged by lightning.
Recommendation For reasons of corrosion and lightning protection, we recommend to use a
nonconductive suspension, e.g. one with low-wear, resistant polypropylene
ropes.
