the RSD-D units to keep the PV modules connected and supplying
energy. This solution complies with NEC 690.12 specifications for
2017, 2020 & 2023 and supports SunSpec signaling for rapid
shutdown.
RSD-D Features:
-
Meets SunSpec requirements
-
Manual rapid system shutdown using the Transmitter breaker
switch -
No automatic shutdown function for arc detection
Transmitter-PLC Features:
- Part of a rapid shutdown solution when paired with RSD-D
- Sends signals to RSD-D units to maintain energy supply
- Comes with one or two cores and optional power supply for
residential or commercial use
Product Usage Instructions:
RSD-D Installation:
-
Ensure the RSD-D is installed according to the provided
manual. -
Connect the RSD-D to the PV modules as per the system wiring
diagram. -
Verify that the RSD-D receives a heartbeat signal from the
Transmitter for normal operation.
Transmitter-PLC Installation:
-
Install the Transmitter-PLC as instructed, ensuring it is on
the same AC branch circuit as the inverter. -
Connect one or two cores and the power supply based on
residential or commercial requirements.
Rapid Shutdown Procedure:
-
To execute rapid system shutdown, use the Transmitter breaker
switch manually. -
In case of abnormal system operation, triggering shutdown by

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.
Safety Instructions
· Do NOT disconnect the PV module from the RSD-D without first disconnecting
the AC power. · Only qualified professionals should install and/or replace the
APsmart RSD-D. · Perform all electrical installations in accordance with local
codes. · Before installing or using the RSD-D, please read all instructions
and cautionary markings in the
technical documents. · Be aware that the body of the operating RSD-D is a heat
sink and can reach high temperature.
To reduce risk of burns, do not touch the body of the RSD-D. · Do NOT attempt
to repair the RSD-D. If it fails, contact APsmart Customer Support to obtain
an
RMA number and start the replacement process. Damaging or opening the RSD-D
will void the warranty.
The power supply of the Transmitter-PLC and inverter MUST be on the same AC
branch circuit as the inverter to meet rapid shutdown requirements.
This device complies with part 15 of the FCC Rules, Operation is subject to
the following two conditions: (1)This device may not cause harmful
interference, and (2) this device must accept any interference receiver,
including interference that may cause undesired operation.
Qualified Personnel:
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, electrical
systems and EMC and is authorized to energize, ground, and tag equipment,
systems, and circuits in accordance with established safety procedures. The
inverter and balance of system may only be commissioned and operated by
qualified personnel.

RSD-D
· Meets NEC 2017, 2020&2023 (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.*(1)(2)
(1) RSD-D does not have automatic shutdown function for arc detection. When the system is abnormal, the transmitter signal is cut off by pulling the gate, which triggers shutdown.
(2) RSD-D is designed to reduce the risk of fire suppression but does not solve the risk of a arc fire.

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 690.12 specifications for
2017, 2020 & 2023 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.
The 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 a residential or commercial project.

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. WARNING: When connecting the RSD-D to only one PV
module, use INPUT1 port ONLY, then short both terminals of INPUT2 directly,
otherwise the RSD-D may be damaged. The DC output voltage remain same. NOTE:
Please use the same type of DC connector as the RSD in the system. The RSD
damage caused by using different type of DC connector will not be covered by
the warranty.
