Transportation and storage
The modules of the surge arrester are packed in boxes or crates in the factory in accordance not only
with the stresses and climatic conditions they will encounter during shipping. but also with the require-
ments of the customer.
The packaging will have the appropriate transportation and storage labelling as well as instructions on
proper handling.
The consignment should be inspected immediately after receipt for signs of damage. If damage is
found the carrier should be informed without delay. Loose parts packed with the consignment should
be checked against the dispatch note to make sure none is missing. This means that all shipping con-
tainers will need to be opened.
If the items are to be stored for extended periods, we recommend you leave the modules and accesso-
ries in their shipping containers.
All of the screws, terminals and supplementary equipment (tell-tale spark gap, surge counter) required
for assembly and installation are supplied in an accessory pack.
Note
:
To avoid damaging the insulators, do not remove the assembly and shipping protector
until assembly and installation has been completed.
