Grounding connection

The RF650R can be electrically connected to the ground potential with a contact washer.
The tightening torque must be increased in this case to ensure that electrical contact is made
(2.7 Nm).
Hazardous voltage due to lightning strikes
Death or serious injury may occur as a result of lightning strikes to antennas mounted
outside buildings.
If the reader is operated with antennas mounted outside buildings, it is imperative that the
reader is electrically connected to the ground potential.
NOTICE
Installation only in protected areas
The antenna can be installed in the protected part of a building. When implementing your
lightning protection concept, make sure you adhere to the VDE 0182 or IEC 62305
