Danger!
This device is only permitted to by supplied by a SELV/PELV power supply unit or with safety extra-low
voltage (SELV) per IEC 61010-2-201.
The necessary 2-pin connector is not included in delivery; for suitable accessories, see "TB6102" on page 100 .
The device is protected against overload and reverse polarity by a soldered fuse (10 A, very 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.
