1. Introduction 1. Introduction SEE a The Solis Raped Shutdown Device has not been qualified or tested with any other Inverters besides the fallowing: Do not uss with other Inverter manufacturers. The Solis Rapid Shutdown Devices (RED) are certified to the UL 1741 inverter standard and comply to all 2014 National Electrical Code 690.12 Raped Shutdown requirements, Solis RSs are packaged inside 8 NAME 4X assurances that fit neatly under the modules. The RED Is controlled by an AC signal circuit.
2.Safety Instructions 2.Safety Instructions Improper uss may result In potential strict shock hazards or burns. This manual contemns Impotent instructions that must be followed during Installation and maintenance. Please rend theses instructions carefully before uss and keep them for future reference. 2.
3. Installation 3. Installation 3.1 System Diagram The Gin long Rapid Shutdown Device is controlled by an AC signal circuit. HAC powers cut at the utility service entrance and/or et the inverter AC output circuit disconnect, the RSD will ba deactivated and the PV array will drop to less than 30 volts in less than 10 seconds (par 2014 NEC 880.12}. solipsism Lis I Sole-REDIL-1G EE 7 fern \_ Figure 3. 1 System diagram J 3.2 Installation The RSD is designs to mount on the rack under PV modules. Step 1.
3. Installation 3. Installation Figure 3. 4 Connect DC input connectors J Figure 3.3 Fix the screws a. Connect inverter DC input to the inverter input channels in the wiring box. Tap 2 Using MC4 connectors, connect the DC Input and DC output wires. WARMING: The string input PV and FY must match RSD PY+ and PY-. Revers PY input polarity could damages the RED and will void the warranty, ASSAIL DC connection: The single Shanna! Solis-RED-1G is rated for 20 amps.
3. Installation 3. Installation Each RSD comes with a ground clip that can accommodate 2 single AWG conductor. Check your local code for grounding conductor sizing requirements. if grounding cannot be achieved through the chassis, Barlow is an optional grounding terminal. Connect the grounding electrode conductor to the RSD ground clamp. Torque the RSD ground clamp to 20 in-lbs, 2.25 Nom. The racking and module could be grounded to this conductor using a crimp connection.
5. Troubleshooting WARMING: The RSD and all ac connections fo the nullity grid must only be mads by qualified personal. Failure of the RSD could interrupt DO power to the inverter. If the installer checks the DG input terminals at the inverter and does not detect PY voltage, the installer should follow the procedures below: a. Hack DO string voltages at the Inverter as a way to Isolate the issue tithe RSD or to the inverter. b.
