Drawing is in approximate relative scale. 2. Tanks are 10 meters between centers. 3. DOM cables are 17 meters long. 4. RS485 Master source is controlled by plugging in the desired data cable. 5. Tank power source is controlled by plugging in desired power cable. 6. Power Converter contains +/-48VDC to 24VDC converter and EMI filter.
