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
– P24EXT1: Fuse 2.5 A / 250 V
– P24EXT2: Fuse 8 A / 125 V
2.5 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
2
).
CAUTION
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
