1.2 INSTRUCTIONS FOR USE
The AMS01 reader is dedicated to monitor electrical equipment like switchgears. The temperature of
live conductors is measured by SAW sensors and prevent overheating and overload. Partial discharges
are measured by antenna pairs and prevent equipment failure. Ambient temperature and humidity
measurements are also available through an optional environmental sensor connected with wires to
the reader.
The reader is intended to be installed in low voltage compartments of switchgear or in similar type of
assets. It can also be installed in a weatherproof environmental enclosure.
The reader is intended for use at a maximum altitude of 5 km, typically between -20°C to +70°C (refer
to reader specification for the complete specification) and between 10% to 95% non-condensing
relative humidity.
WARNING
THE READER IS NOT INTENDED FOR INSTALLATION INTO MEDIUM OR HIGH VOLTAGE COMPARTMENT
ASSETS. ONLY SAW TEMPERATURE SENSORS, ENVIRONMENTAL SENSOR AND RF ANTENNAS ARE
INTENDED FOR INSTALLATION INTO MEDIUM VOLTAGE COMPARTMENTS.

1.7 DIN RAIL MOUNTING
CAUTION
ENSURE THAT THE LOW-LEVEL COMPARTMENT WHERE THE READER IS MOUNTED IS SUFFICIENTLY
VENTILATED TO PREVENT OVERHEATING. THE DEVICE MUST BE ELECTRICALLY GROUNDED FOR EMC
COMPLIANCE.
The reader is designed for installation on a grounded 35 mm DIN rail. The reader could be mounted in
two different positions to facilitate integration.
Using the fixing clip and the two screws provided, screw it onto the box enclosure according to the
preferred orientation.
SENSeOR recommends to mount the device vertically with antennas output to the top.

1.7.1 READER EMPLACEMENT
The reader is intended to be installed in the low voltage compartment of the switchgear. The other
electrical assets are recommended to be weather protected in an enclosed location.
The reader is required to be installed within a maximum distance of 10 meters from the antennas,
corresponding to the maximum length of the antenna coaxial cable for SAW temperature sensors and
partial discharge measurement.
1.7.2 RECOMMENDED SPACING
For connectors access, it is recommended to leave the minimum clearance for top and bottom panels
of 5 cm (2 inches).

WIRING
1.8 POWER
The reader power connector is a 2-pin male connector. This screw connector supports from 16 to 26
AWG wires. For stranded conductor use connector ferrules on the termination.
1.8.1 INPUT POWER
The reader operates at 24VDC nominal with a total power consumption of 6 Watts maximum.
SENSeOR recommends the use of a DC power supply in the same low-voltage compartment as the
reader. It is possible to run a DC power bus to power multiple readers from one DC power supply.
However, this option requires a careful consideration of the wire diameter, AC/DC and circuit breaker
capabilities.
Power connections are recommended to be at a minimum of 16 AWG.
If bussed power is being considered, the wire gauge must be selected to prevent excessive voltage
drop between the DC power source and the reader that is electrically farthest from the source.
The following block diagram outlines the recommended power wiring for the reader with a 2-pole
circuit breaker and an AC/DC power supply. Surge suppression devices can also be installed between
the input line and the neutral only if higher safety rating is required.

1.8.2 RELAY OUTPUT
Output relay connections are recommended to be at a minimum of 16 AWG.
1.8.3 INTERNAL BATTERY
SENSeORreader has an internal 3VDC non rechargeable battery to keep the UTC date and the time in
case of power down. Battery needs to be replaced if voltage value is under 2.1V.
It can be replaced only by authorized person using the following or an equivalent reference:
1.8.3.1 Battery replacement procedure
►Disconnect all the AMS01 reader connections (antennas, environmental sensor, relay and power
supply).
►Using a PZ1 screwdriver, disconnect the ground lug and remove the screw.
►Extract the reader from its location on the DIN rail.
►Remove the 4 screws from the front panel.
►Remove the electronic card from the enclosure.
►Identify and replace the CR2032 battery by carefully respecting its polarity.
►Reinsert the electronic card in the enclosure.
►Screw the front panel on the enclosure.
►Reposition the reader on its location on the DIN rail.
►Reconnect the ground lug with the corresponding screw.
►Reconnect all the AMS01 reader connections (antennas, environmental sensor, relay and power
supply).
WARNING
THERE IS A RISK OF EXPLOSION IF THE BATTERY IS REPLACED BY AN INCORRECT TYPE.
BE CAREFUL OF USED BATTERY IN ACCORDANCE WITH YOUR REGIONAL LEGAL INSTRUCTIONS.
