ATCOVER protectors are installed in parallel with the low voltage line.
When they are installed in combination with other protectors it is necessary that they are separated by a cable of at least 10 meters or, if this is not possible, by an ATLINK type inductance, in order to achieve the correct coordination between them.
The installation must be carried out without tension on the line and can only be carried out by authorized professionals.
Grounding is a must. For the protection to be correct, the grounding of the entire installation must be joined, directly or by means of sparks, and their resistance must be less than 10 Ω.
If in its use or installation the indications of this sheet are not respected, the protection ensured by this equipment may be compromised.
