During production hours, the robot parks in a designated parking platform, attached to the trackers row. The parking platform consists of 2 solar modules, the robots self-charging mechanism. The parking rotates with the row, tracking the suns position. During midday, the robot shifts sides on the parking platform, positioning itself so the charging poles, on its front, will always lean against the peripheral rail in the parking, allowing its batteries to be charged from the electricity flowing from the parking modules. After production hours, the row balances to a horizontal position, enabling the T4 robot to leave the parking and clean the row. 2 Safety Instructions – Working in a solar site Work is carried out within a solar site, generating electricity in direct current (DC). Throughout production hours, there is constant voltage in all cables deployed on the site. 1. Entry to the site will only take place after you have been instructed by the sites safety supervisor. 2. Do not work below the panels array. 3. Do not make any changes to the solar array. 4. Ensure no damage done to arrays solar modules during T4 installation. 5. Only a trained employee may perform the required operations on the site. 6. For any safety concerns - contact the field safety supervisor. 7. Beware electrocution from solar modules wiring and connections, in case they are damaged or exposed. Only a qualified and certified Ecoppia worker may operate the T4 robot T4 User Manual |WP6001 Version 1 Valid as of 11 November 2019 P a g e 4 | 7 C O N F I D E N T I A L 3 Setting Robot on array 1. Open T4 packing box in correct position, with "up" sign in upper direction. 2. Remove robot carefully from box and lay on a clean surface or directly onto docking platform. 3. Position the robot on the WEST docking side, in afternoon hours, while this docking side is accessible. 4. Notice: The T4 robot docking station contains 2 photovoltaic modules, set into the metal docking surface. Both modules generate 12 Volt 2.6- 7.3 Ah, transferred to east and west rails on docking platform. 5. Place T4 robot on the tilted docking surface, "charging poles" leaning against western charging docking rod. Ensure that the stopper rail prevents it from rolling off the table. 6. Attention: Do not hold both docking poles on robot while docking/ charging. This will close an electrical circuit and may result minor shock (12V 10Ah) T4 User Manual |WP6001 Version 1 Valid as of 11 November 2019 P a g e 5 | 7 C O N F I D E N T I A L 7. Remove T4 robots cover, lifting front bumpers first, carefully releasing them from lower bumpers. 8. Connect T4 battery to black and red related wires. This action will generate the docking magnet to rotate and lock into docking surface. 2 led lights on control card will lite to indicate the connectivity. In case this procedure does not lower the magnet, disconnect, press the reset button and repeat to connect the battery. 9. Replace T4 cover. Step 1 - Lift front cover Step 2 - Lift cover from rear Connect battery to control card wire Indication leds Reset button T4 User Manual |WP6001 Version 1 Valid as of 11 November 2019 P a g e 6 | 7 C O N F I D E N T I A L 4 T4 Digital Setting 10. Configure robot on "Master Control" window and "DCT" (Ecoppia Direct Connection array construction. T4 is configured with site relative software. 11. Enter Robot & row relationship into Salesforce system.  Operating Manuals for T4, configuration and data input are available only to Ecoppia technicians and are confidential. 5 T4 Power Consumption The T4 operates on a 12V battery and has a peak consumption of 7.3Amp with average current consumption of 2.6A while working, 0.1A while parking. The communication module CC1310 from TI, is powered by a 3.3V power regulator and a maximum current draw of 25.1mA.
