Mounting the device
WARNING
Risk of injury due to damage to the device
!
For reasons of safety, if a device shows visible signs of damage do not put it into
operation, or take it out of operation immediately.
Possible damage (depending on type):
•
Housing: cracking, splitting or fracture
•
Electrical connections (male connector or female connector): cracks or detach‐
ment from the housing
NOTICE
Risk of damaging the device!
Observe the maximum screw-in depth of the blind tapped holes on the device. Longer
screws than the specified screw-in depth damage the device.
b
Use screws of suitable length.
Basic assignment of the device to the transponders
UHF transponders have dipole antennas and therefore preferential directions within
the radiation field of the antenna. The transmitting and receiving performance will be
higher or lower depending on the orientation of the dipole antenna of the transponder
to the axis perpendicular to the antenna surface. The read and writing rate and sensing
range can therefore be subject to fluctuations.
NOTE
If the dipole antenna of the transponder is oriented lengthwise along the axis perpen‐
dicular to the antenna surface, no reading or writing of the transponder will be possible.
