6.3 Instructions for electrical installation when the ambient temperature can fall below
0 °C
NOTE
For mounting instructions, see "Mounting instructions for ambient temperature range
below 0 °C", page 25
All device variants can also be operated at low ambient temperatures. For details, see
"Technical data", page 47
6.3.1 Prerequisites
• Required supply voltage: see "Supply voltage", page 33
• Use SICK IO-Link standard cables for the specified ambient temperature range,
see:
°
www.sick.com/RFU61x
• Do not operate the device at ambient temperatures below 0 °C when mounting or
connection work is being carried out.
• Perform all connection work only in the ambient temperature range 0 °C to
+50 °C. Secure the connecting cables.
• The side cover of the memory card slot must be screwed tight to the device.
• All cables connected to the device must be clamped. The M8 connection, which
may not be used, is sealed with a tightly screwed protective element, e.g. a
protective cap as delivered.
• When operating the device at the lower limit of the permissible ambient tempera‐
ture range (
see "Technical data", page 47 ), do not expose the device to strong air
flows (e.g. ventilation system, wind).
6.3.2 Behavior of the device when switched on
Once the supply voltage has been applied and initialization has been completed,
the device can be addressed immediately with a configuration tool, e. g. SOPAS ET,
TIA Portal, TwinCat.

Internal temperature of
housing Behavior
Below –25 °C “Ready” LED continuously flashes orange.
Device is not operational because –25 °C is below the specified
minimum limit value.
