General information
Danger
Incorrect wiring can lead to serious injury from
electrical current and result in appliance dam-
age.
■
Route extra low voltage (ELV) leads < 42 V
separately from cables > 42 V/230 V~.
Strip as little of the insulation as possible,
■
directly before the terminals. Bundle cables
close to the corresponding terminals.

Please note
Not grounding or incorrectly grounding the top-
hat rail can lead to damage to the components
and to interference during data transmission.
Ground the top-hat rail as shown in the following
diagram.
The gateway is connected to the public low voltage
network via the power supply unit (standard delivery).
Mains type TN-S/TT: Separate neutral and protective
conductors in the entire system.
The mains voltage should be single-phase, 100 to
240 V, 50/60 Hz and must be within the voltage range
limits defined in the VDE regulations.
