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 per-
ceive 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, refrigera-
tion 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 com-
missioned and operated by qualified personnel.

RSD PRODUCTS
RSD-S-PLC
· Meets NEC 2017 (690.12) requirements
· Executes rapid shutdown of system
· Meets SunSpec requirements

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.

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
complies with NEC 690.12 specifications for 2017 and supports the SunSpec signaling for rapid shut-
down.
The Transmitter-PLC includes one or two cores and an optional power supply: 85-264VAC for
residential, 180-550VAC for commercial.

RSD-S-PLC INSTALLATION
INSTALLATION NOTES
Installation MUST comply with local regulations and technical rules：
①Perform all electrical installations in accordance with local codes.
②Be aware that only qualified professionals should install and/or replace the RSD-S-PLC.
③Before 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.
④Be aware that installation of this equipment includes the risk of electric shock.
⑤Do not touch any live parts in the system, including the PV array, when the system has been
connected to the electrical grid.
⑥Ensure the solar module and inverter has been disconnected before installing an RSD-S-PLC.
Additional installation components from APsystems
Required parts and tools to complete the installation
· DC extension cable (sold separately)
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
①Be sure to verify the voltage and current specifications of your PV module match with those of
the RSD-S-PLC.
②You must match the DC operating voltage range of the PV module with the allowable inpust
voltage range of the RSD-S-PLC.
③The maximum open circuit voltage of the PV module must not exceed the specified maximum
input voltage of the APsystem RSD-S-PLC.

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.

TRANSMITTER-PLC INSTALLATION
• 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
No
Note: If there is only one core need to connect, please connect Core 1 first.
te: Install RSD-S-PLC before powering on Transmitter.
Place rapid shutdown system label no more than 1m (3ft) from Transmitter or AC
disconnect if not at same location.
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.
