SICK RFU610-10600

NOTE
UL-certified devices (see type label) require a supply voltage according to ES1, EN
62368-1, NEC protection class 2 (UL13010).
The power source must be able to provide the following power outputs when the device
is operating at maximum transmitting power:

RFU61x-106xx DC 18 V ... 30 V -25 °C ... +50 °C At least 6 W
DC 48 V / 57 V according
to PoE technology
Power supply options
The device offers two voltage supply options:
1. Power and Ethernet: DC 18 V ... 30 V
°
Connection 1: power
°
Connection 2: Ethernet
2. Power over Ethernet (PoE): DC 48 V / 57 V according to PoE technology
°
Connection 1: not assigned
°
Connection 2: PoE
It is possible to use both variants at the same time. However, it is recommended to
select just one variant.

Voltage supply with immediate
effect via PoE to connection 2.
NOTE
The voltage supply via a power supply unit must be capable of buffering a brief power
failure of 20 ms.
Protecting the supply cables
To ensure protection against short-circuits and overload in the customer-supplied
cables, the wire cross-sections used must be selected and protected in accordance
with national regulations.
The following standards must be observed in Germany:
•
DIN VDE 0100 (part 430)
•
DIN VDE 0298 (part 4) and/or DIN VDE 0891 (part 1)
When the device is supplied via the “Power” connection, fuse the supply voltage DC
18 V to 30 V with a separate 0.8 A slow-blow fuse.
b
Install the fuse in the supply circuit at the start of the supply cable.
