Antenna connection cables (optional accessory)
RFU63x
NOTE
Length of connecting cables
•
To avoid a significant attenuation in the UHF output power of the device due to the
cables, use the shortest possible cable lengths for the external antennas.
•
Details of the length-dependent losses in SICK cables can be found in the “Acces‐
sories” section online at:
Conditions for specified enclosure rating
To maintain the specified enclosure rating of the device (IP67) during operation, the fol‐
lowing requirements must be met. If these requirements are not met, the device does
not fulfill any specified enclosure rating.
•
The side cover for the USB socket and the microSD card slot must be screwed
tight to the device. Recommended tightening torque for the cover screws: 40 Ncm
±5 Nm.
•
The cables plugged into the electrical M12 connections must be clamped.
•
Unused M12 connections must be fitted with screw-on protective caps (for male
connectors) or plugs (for female connectors) as supplied.
•
RFU63x: Unused electrical connections for external antennas (female connector,
TNC reverse) must be fitted with metal screw-on protective caps as supplied.
•
The same also applies to the EMC requirement (ESD) according to CE.
NOTICE
The device can, if necessary, be operated for a short time
without the side cover
to per‐
form the following tasks:
•
Inserting or removing the optional memory card
•
Temporary use of the USB interface as a servicing interface
During this time, protect the device against moisture and dust.
6.1.2
Prerequisites for safe operation of the device
WARNING
Risk of injury and damage caused by electrical current!
As a result of equipotential bonding currents between the device and other grounded
devices in the system, faulty grounding of the device can give rise to the following dan‐
gers and faults:
■
Metal housings are vulnerable to dangerous currents.
■
Devices will behave incorrectly or be destroyed.
■
Cable shielding will be damaged by overheating and cause cable fires.
Remedial measures
■
Only skilled electricians should be permitted to carry out work on the electrical sys‐
tem.
■
If the cable insulation is damaged, disconnect the voltage supply immediately and
have the damage repaired.
■
Ensure that the ground potential is the same at all grounding points.
■
Where local conditions do not meet the requirements for a safe earthing method,
take appropriate measures (e.g., ensuring low-impedance and current-carrying
equipotential bonding).
