ELECTRICAL INSTALLATION GUIDELINES
Electrical installation of the sensor consists of a simple cable connection on the radar
side. Figure 13 contains the electrical schema of this cable. For safety and warranty
reasons users must use only cables supplied by Magos. Users must also ensure that
that connector shielding on the RJ45 connector side is properly grounded.

Ensure that the SR Radar is powered only from an IEEE 802.3at Type 1 (802.3af) and
Type 2 certified POE injector/switch which is in conformance with all safety and EMC
standards that are relevant and applicable in your country. If you are unfamiliar with
such standards it is recommended that you contact Magos and enquire as to the
compatibility of the suggested power supply.
Electrical requirements of the power supply are 48V and 15W, according to IEEE
802.3at Type 1 (802.3af) and Type 2. Using power supplies that do not meet these
requirements and/or are not properly authorized for public use in your country is under
the sole responsibility of the user, and might result in unexpected sensor behavior or
even irreversible damage to the unit.
An example for such a POE supply can be found here: POE injector . Note that this is an
indoor unit that can be useful for initial sensor configuration only and cannot be used in
outdoor fixed installations.
