IMPORTANT SAFETY INSTRUCTIONS This manual contains important instructions to be followed during installation and maintenance of the APsmart RSD-D and Transmitter. To reduce the risk of electrical shock and ensure the safe installation and operation of the APsmart RSD-D and Transmitter, the following symbols appear throughout this document to indicate dangerous conditions and important safety instructions.
RSD PRODUCTS RSD-D · Meets NEC 2017 & 2020 (690.12) requirements · Executes rapid shutdown of system when Transmitter-PLC signal is absent · Meets SunSpec requirements · Dual-input channel The RSD-D meets SunSpec requirements, maintaining normal function by continually receiving a heartbeat signal from the APsmart Transmitter. The RSD-D executes rapid system shutdown when the Transmitter signal is absent. Users can manually execute rapid shutdown using the Transmitter breaker switch.
TRANSMITTER PRODUCTS Transmitter-PLC · Meets NEC 2017&2020 (690.12) requirements · Switching off Transmitter-PLC results in rapid shutdown of the output of PV modules · Meets SunSpec requirements · Equipped with single/dual core · Optional 85-264VAC power supply · Optional 180-550VAC power supply Transmitter-PLC-Outdoor Kit · Meets NEC 2017&2020 (690.
SYSTEM WIRING DIAGRAM The APsmart Rapid Shutdown System Transmitter-PLC is part of a rapid shutdown solution when paired with the APsmart RSD-D, a PV module rapid shutdown unit. While powered on, the Tansmitter-PLC sends a signal to the RSD-D units to keep the PV modules connected and supplying energy. RSD-D units automatically enter rapid shutdown mode when the Transmitter-PLC is switched off and resume energy production when power is restored to the Transmitter-PLC. This solution complies with NEC 690.

RSD-D INSTALLATION INSTALLATION NOTES Installation MUST comply with local regulations and technical rules： ① Perform all electrical installations in accordance with local codes. ② Be aware that only qualified professionals should install and/or replace the RSD-D. ③ Before installing or using an RSD-D, please read all instructions and warnings in the technical documents and on the inverter system itself as well as on the PV array.
RSD-D INSTALLATION Step 1: Install the RSD-D. OUTPUT- INPUT2+ INPUT1+ INPUT2- INPUT1- OUTPUT+ Mounting brackets Buckle RSD-D onto the PV module frame. A. Back buckle B. Front buckle NOTE: Do not place the RSD-D (including DC connectors) where exposed to the sun, rain or snow, even gap between modules. Allow a minimum of 3/4’’(1.5cm.) between the roof and the bottom of the RSD-D to allow proper air flow.
RSD-D INSTALLATION Step 2. Connect the INPUT1 connectors of the RSD-D to the first PV module junction box and connect the INPUT2 connectors to second PV module, the device DC output voltage is within the range of 1.2 ~ 2v. NOTE: Do not short-circuit the RSD-D output connectors, otherwise it will be damaged. RSD-D cable length Note: The output cable length of triad junction box PV module should be no less than 1.2m. ≥1.
RSD-D INSTALLATION NOTE: When installing RSD-D cable, the bending radius of the cable near the casing must be greater than 50 mm. Step 3: Connect the output ports of two adjacent RSD-Ds in series and then connect to the inverter with a self-made DC extension cable. NOTE: Do not connect homerun to inverter before finishing all strings connections and tests.
TRANSMITTER-PLC INSTALLATION Note: If there is only one core needed, connect using Core 1 terminal. Transmitter-PLC power supply must be on same AC branch circuit as inverter to meet rapid shutdown requirements. During operation, the Power LED should be lit and the Signal LED should be blinking. If the TransmitterPLC fails to work, the Signal LED will not be blinking. If the Power LED is also not lit, check the power supply first. Note: Install the RSD-D before powering on the Transmitter-PLC.
TRANSMITTER-PLC INSTALLATION Note: Install the RSD-D before powering the Transmitter-PLC. Note: The waterproof jacket and related accessories are not configured before delivery and customers need to buy by themselves. • Pass either positive or negative cables through cores (either both positive cables or both negative cables. Do not use one positive and one negative cable.
