(1) Required in cases where there is higher nominal current installed upstream from the protector

ATSHOCK surge protection devices are to be installed in parallel with the low voltage supply line, connected to a phase and ground (ATSHOCK L) or to neutral and ground (ATSHOCK N). One ATSHOCK L is needed for each phase.

Installation should be carried out without power running through the line.

ATSHOCK can be installed in combination with ATSUB or ATCOVER protectors. In either case, both must be separated by at least 10 metres of cable or, if this is not possible, by an ATLINK decoupling inductor, in order to achieve correct coordination between them.
