APsmart RSD-S-PLC Rapid Shutdown System User Manual

IMPORTANT SAFETY INSTRUCTIONS

This manual contains important instructions to be followed during installation and maintenance of the
APsmart RSD and Transmitter. To reduce the risk of electrical shock and ensure the safe installation and operation of the APsmart RSD and Transmitter, the following symbols appear throughout this document to indicate dangerous conditions and important safety instructions.

Safety Instructions

• Do NOT disconnect the PV module from the RSD-S-PLC without first disconnecting the AC power.
• Only qualified professionals should install and/or replace the APsmart RSD-S-PLC.
• Perform all electrical installations in accordance with local codes.
• Before installing or using the RSD-S-PLC, please read all instructions and cautionary markings in the technical documents.
• Be aware that the body of the running RSD-S-PLC is the heat sink and can reach high temperatures.
• To reduce risk of burns, do not touch the body of the RSD-S-PLC.
• Do NOT attempt to repair the RSD-S-PLC. If it fails, contact APmart Customer Support to obtain an
  RMA number and start the replacement process. Damaging or opening the RSD-S-PLC will void the warranty.
  The Transmitter-PLC control power supply MUST be on the same AC branch circuit as the inverter to meet rapid shutdown requirements.

Symbols replace words on the equipment, on a display, or in manuals

Qualified personnel:

1. Person adequately advised or supervised by an electrically skilled person to enable him or her to perceive risks and to avoid hazards which electricity can create. For the purpose of the safety information of this manual, a “qualified person” is someone who is familiar with requirements for safety, refrigeration system and EMC and is authorized to energize, ground, and tag equipment, systems, and ircuits in accordance with established safety procedures. The inverter and endues system may only be commissioned and operated by qualified personnel.
   

RSD PRODUCTS RSD-S-PLC

• Meets NEC 2017 (690.12) requirements
• Executes rapid shutdown of system
• Meets SunSpec requirements 2 when Transmitter-PLC signal is absent

RSD-S-PLC meets SunSpec requirements,maintaining normal function by continually receiving a heart-beat signal from the APsmart Transmitter. The RSD executes rapid system shutdown when
Transmitter signal is absent. Users can manually execute rapid shutdown using Transmitter breaker switch.

SYSTEM WIRING DIAGRAM

The APsmart Rapid Shutdown System Transmitter-PLC is part of a rapid shutdown solution when paired with APsmart RSD-S-PLC, a PV module rapid shutdown unit. While powered on, the
Transmitter-PLC sends a signal to the RSD-S-PLC units to keep their PV modules connected and supplying energy.
RSD-S-PLC units automatically enter rapid shutdown mode when the Transmitter- PLC is switched o and resume energy production when power is restored to the Transmitter-PLC. This solution complies with NEC 690.12 specifications for 2017 and supports the SunSpec signaling for rapid shutdown.
The Transmitter-PLC includes one or two cores and an optional power supply: 85-264VAC for residential, 180-550VAC for commercial.
Transmitter-PLC Outdoor Kit includes a Transmitter-PLC with one or two Cores, outdoor enclosure, 85-264VAC or 180V-550VAC power supply. It could be used in residential or commercial project.

RSD-S-PLC 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-S-PLC.

3. Before installing or using an RSD-S-PLC, please read all instructions and warnings in the technical documents and on the inverter system itself as well as on the PV array.

4. Be aware that installation of this equipment includes the risk of electric shock.

5. Do not touch any live parts in the system, including the PV array, when the system has been connected to the electrical grid.

6. Ensure the solar module and inverter has been disconnected before installing an RSD-S-PLC.

7. Be sure to verify the voltage and current specifications of your PV module match with those of the RSD-S-PLC.

8. You must match the DC operating voltage range of the PV module with the allowable inpust voltage range of the RSD-S-PLC.

9. The maximum open circuit voltage of the PV module must not exceed the specified maximum input voltage of the APsmart RSD-S-PLC.

Note: RSD-S-PLC units could be installed only on some strings, NO need to be all in an inverter. With our patented proprietary design, there is no risk.

Additional installation components from APsmart

• DC extension cable (sold separately)

Required parts and tools to complete the installation

In addition to your PV array and its associated hardware, you will need the following items:

• Rapid shutdown device installation kit (screw, nut)
• A torque wrench and a Phillips screwdriver

Step 1: Install the RSD-S-PLC

Note: Both installations can be installed anywhere on the PV module frame.

Step 2: According to the component arrangement, connect the output port of the RSD-S-PLC and connect the input port to the junction box.

Step 3: Connect the RSD-S-PLC serially connected output to the inverter with a self-made DC extension cable.

self-made DC extension cable

TRANSMITTER-PLC INSTALLATION

Note: If there is only one core need to connect, please connect Core 1 first.

T During operation, the Power LED should be lit and the Signal LED should be blinking.
When Transmitter fails to work, the Signal LED will not be blinking. If the Power LED is also not lit, check the power supply first.
ransmitter power supply must be on same AC branch circuit as inverter to meet rapid shutdown requirements.

Note Install RSD-S-PLC before powering on Transmitter.

• Mount Transmitter-PLC and power supply on DIN rail
• Connect DC leads from power supply to Transmitter-PLC
• Connect single/dual core(Core 1 and Core 2) to Transmitter-PLC

Place rapid shutdown system label no more than 1m (3ft) from Transmitter or AC disconnect if not at same location.]

Note: Install RSD-S-PLC before powering on Transmitter.

• Pass either positive or negative homerun through Cores • Connect wires to AC side of Plower supply

Max number Of Strings Per Core :

DC cable Diameter Number Of Strings Per Core (without connector) ≤15 ≤15 ≤14 ≤10 5.9mm 6.35mm 7mm 8.6mm
