No use in potentially explosive areas!
Use in hazardous areas can result in death, serious injury or considerable damage to
property.
The device is not designed for use in hazardous areas and does not have the appropriate
approvals.

Power supply
Supply voltage: +24 VDC ±20 %
Current consumption: 0.15 A – 1 A
Power consumption
1
: 3.6 W – 24 W
Internal fusing: 2A melting fuse
External fusing with max.40A fuse required
On primary side overvoltage category II max. 300V
Recommended design of the power supply unit: Voltage/ output power: 24 VDC / min. 30 W
The output of the power supply unit must meet the criteria of a safety extra-low voltage
(SELV) according to IEC 60664-1.
The use of an unsuitable power supply unit can result in danger of electric shock.
The power cable must be rated for a temperature of +75° C or higher.
The cable can become damaged over time or potentially harmful plasticizers could be
released in the surrounding air if cables with a lower temperature rating are being used.
The power consumption depends on the configuration as well as the type and number of
active interfaces.
The internal fuse is not replaceable. Defective fuses must be replaced by qualified Kontron
service.
USB devices connected to USB 2.0 interfaces may consume a maximum of 0.5A per interface.
