3 INSTALLATION
3.1 SAFETY PRECAUTIONS
The following safety precautions must be observed during normal use, service and
repair.

The ANPR shall be connected to safety ground.
 Disconnect the power supply before removing any parts.

The ANPR shall only be installed and serviced by qualified and trained
personnel.

To be sure of safety, do not modify or add anything other than mentioned in
this manual or indicated by NEDAP N.V.

CAUTION: for continued protection against risk of fire, replace fuses only
with the same type and rating.

The ANPR can be powered from a low power, Class 2 power supply, in
compliance with local regulations.

The ANPR is equipped with an 850nm Infrared illuminator. The human eye
will not or slightly see this light coming from the illuminator. Do not look
into the ANPR lens directly from close range or for more than 100 seconds.
Eyes can be damaged by not taking these precautions. During normal use of
the ANPR at a vehicle gate, reading plates, there is no risk to the public.
3.2 MOUNTING
The ANPR is intended for vehicle access control. Vehicles are identified by the
number plate when approaching the gate. Because the number plate recognition is
very fast, a full stop is normally not necessary. The ANPR covers a reading distance
of 3 to 6 meters. The field of view is typically one lane wide. There are 2
recommended positions for the ANPR.
3.2.1 POLE MOUNTING
The ANPR is positioned directly behind or in front of the actual barrier onto a pole. In
that case the ANPR can be best positioned on a pole at maximum 2m20 height. In
this position the number plate of the vehicle directly in front of the barrier cannot
be read anymore. So these vehicles need to be recognized in flow. Mounting the
ANPR at 2m20 height is here the best option. When overhead installation is an
option, the ANPR can at best be installed in the center of the lane, above the lane.
Horizontal angle will be 0° in that case, which is good.
