Grounding - Siemens SIMOTION ADI4 Manual

CAUTION
The external supply voltages must each be generated as functional extra-low voltage with
safe electrical isolation (DIN EN 60204-1, PELV).
Fuse
On the module side, supply voltages P24EXT1 and P24EXT2 must be protected against the
following:
● Overvoltage
● Short-circuit (electrical current limiting of outputs)
● Polarity reversal
● Overload

Grounding

Grounding
The module must be installed according to EN 60204.
The user must ground each of the supply voltages. To do this, a connection must be
established from Terminal X1, Pin 2 (MEXT1) or X6-1, Pin 15 (MEXT2) to a central
grounding point of the system.
If a large-area, permanent metallic connection with the central grounding point is not
possible using the rear panel, the module must be connected to the grounding rail by means
of a wire (cross-section > 10 mm
A protective conductor must be connected. An M6 screw is provided on the lower right of
the front of the housing to connect the protective conductor. See "Overview of connections
(Page 11)".
