4.1.5.2.2 +24 VDC power supply
Danger!
The device is only permitted to be supplied with a SELV/PELV power supply or with safety extra-low
voltage (SELV) per EN 60950.
The necessary 3-pin connector is not included in delivery; for suitable accessories, see
.
The device is protected against overload and reverse polarity by a soldered fuse (15 A, fast-acting). If the fuse
is defective (e.g. due to overload), the device must be sent to B&R for repairs. If the polarity is reversed, it is not
necessary to replace the fuse.

4.1.5.2.2.1 Grounding
Caution!
The functional ground (power supply pin 2 and ground connec-
tion) must be connected to the central grounding point (e.g. con-
trol cabinet or system) via the shortest possible path with the low-
est possible resistance and with the largest possible wire cross
section. This type of grounding is mandatory for proper function-
ality.
