Surge Arresters
Overview
Acti 9 surge arresters can be connected to I/O Smart Link:
-
The remote transfer contact (indication contact: NO) of an Acti 9 surge arrester can be connected to input I1 or I2 of an I/O Smart Link channel.
-
The SD fault-trip indication contact (indication contact: NC) of the circuit breaker associated to an Acti 9 surge arrester can be connected to input I1 or I2 of an I/O Smart Link channel.
Wiring
An indication contact can be connected with an A9XCAU06 or A9XCAC01 pre-wired cable: molded connector (at I/O Smart Link end), and with the five wires (indication contact end).
The following wiring is dedicated to surge arresters:
-
iPRD (with a commercial reference ending by 1)
-
iPRD DC
-
iQuick PRD
-
iQuick PF (with remote auxiliary)
-
iPRF1 12.5r
-
PRD1 25r and PRD1 35r
-
PRD1 Master
-
@updatedD8A maximum of one wire can be connected in each Ti24 connector terminal (A9XC2412).
-
Do not connect a wire with cable end in each of the Ti24 connector terminals.
