Installation 15
devolo dLAN pro 1200 DINrail
DANGER!
Risk of fire caused by incorrect conductor
cross-section and improper installation of the
power supply
Comply with the specified conductor cross-
sections and ensure the power supply is cor-
rectly installed
쑗 Single-phase connection: Neutral conduc-
tors and external conductors are connected to
terminals N and L1 (see Fig. 4).
쑗 Three-phase connection: Neutral conduc-
tors and three external conductors are
connected to terminals N, L1, L2 and L3. The
device is supplied with power via terminals
N and L1 (see Fig. 5).
쑗 PE connection: Connecting the earth wire to
the PE terminal is optional but it provides an
even more stable network connection with
significantly longer range (range+) thanks to
MIMO technology.
Single-phase connection without residual cur-
rent circuit breaker
In general, connection of the
dLAN pro 1200 DINrail to one phase and to
one neutral conductor is adequate, even for
communicating over multiple phases. To opti-
mise the data transmission, however, we re-
commend a connection with all three-phases
and earth wire (PE).
