The connection from ATG to ATG is made using a
flatband cable (ATE2 after ATE1) and a 2‑pin cable
(SUA1/2 after SUA1/2).
Potential equalization.
Ground connection is required and has to be
connected to the housing metal parts.
If shielded cables are used, the shield wire has to be
connected to the PE pin of the first ATG 420 LSNi (left
side of the housing). Do not connect shield wires to
local ground used in 2).
Wires aLSN and bLSN of cable 1 (C1) have to be
connected to the pins aLSN1 and bLSN1 of the first
ATG 420 LSNi (left side of the housing).
Wires aLSN and bLSN of cable 2 (C2) have to be
connected to the pins aLSN2 and bLSN2 of the last
available ATG 420 LSNi in the housing.
For AUX power: Cable 1 (C1) and cable 2 (C2) have to
be connected to the same ATG 420 LSNi module.
In installations where ATG 420 LSNi modules are
installed in the same housing (e.g. BAT100) as ATG100
modules and therefore share the same lamp test
button, it is required to swap the wires for the lamp
test function. Connect the signals SUA1 of ATG 420
LSNi to SUA2 of ATG100 and signals SUA2 of ATG 420
LSNi to SUA1 of ATG100 to avoid unintended behavior
of the lamp test function.
