6.1 Safety instructions for electrical connection
When carrying out any work, carefully observe the information provided in Chapter "Safety
instructions (Page 13)".
Danger due to incorrectly sealed cable entry
If the cable entry is not correctly sealed, it is possible that the device no longer complies with
the requirements associated with the specified degree of protection.
Operation with an insufficient degree of protection can result in death, serious injury and
material damage.
● To maintain the degree of protection, after connecting the cable, immediately seal the cable
entries so they are air-tight.
Danger caused by changing the floor panel or the roof panel
If you make any changes to the floor panel or the roof panel in order to modify the cable entry,
the changes may mean that the requirements related to the specified degree of protection are
no longer complied with. If there are any holes in the floor or roof panel, then animals and
vermin, for example, can get into the device while it is operational.
When operated with an insufficient degree of protection, this can result in death, serious injury
and material damage.
● To maintain the degree of protection, after installation, immediately seal the holes so they
are air-tight.
