4. SENSORS INSTALLATION
4.1. SENSOR LOCATION
The sensors are mounted on the equipment to monitor following the rules for vibration
sensor installation.
Leave enough space around the sensor to ensure the best transmission/reception possible
of radio signals. At least 100 mm around the device antenna (plastic cap). If the sensor has
to be installed in tiny spaces, the use of an expander might be a solution to improve the radio
coverage (if necessary).

4.2. MOUNTING INFORMATION FOR SENSORS
A damp cloth should be used when installing or taking off the gateway in hazardous areas to
eliminate static electricity resulting from this operation.
