5.1.4 Power supply
5.1.4.1 PoE power supply
For PoE power supply [}3.2.6], a PSE (Power Sourcing Equipment) must be provided on the
network cable for power feeding.
Possible methods for feeding the power supply via the PSE:
• End span (direct supply, e.g. via PoE switch)
• Midspan (supply via intermediate sources, e.g. PoE injector)
5.1.4.2 24 V DC power supply
Devices with docking station equipped with BEX121 motherboard. It has a 24 V DC input with
overvoltage protection and transient filter for supplying power to the terminal.
Only power supply units that fulfil the following requirements may be used for power supply:
LPS (Limited Power Source) and SELV (Safety Extra Low Voltage) in accordance with IEC/
EN/UL/CSA 60950-1 or ES1 and PS2 in accordance with IEC/EN/UL/CSA 62368-1.
5.1.4.3 Mains voltage supply
Only devices with docking station equipped with BEX120 motherboard. It has a 100-240 V AC
mains voltage input and an integrated limited power source power supply unit (LPS).
The mains voltage supply can be designed as stationary wiring or as separable connection.
For the terminal, a separate fuse-protected circuit must be provided. If the mains voltage
supply is designed as a separable connection, the following applies:
• The mains socket with grounded contact must be in the immediate vicinity of the device.
• The mains plug must be freely accessible.
If the mains voltage supply is designed as stationary wiring, the following applies:
• An easily accessible circuit breaker must be provided.
• The circuit breaker (LS) must be designed for max. 10 A.
• The electrical system of the building must be equipped with an all-pole supply circuit
switch.
