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

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-PLC. The RSD executes rapid system shutdown
when Transmitter-PLC signal is absent. Users can manually execute rapid shutdown using
Transmitter-PLC breaker switch.

SYSTEM WIRING DIAGRAM
①RSD-S-PLC
②Transmitter-PLC
③Inverter
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&2020 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：
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 PV modules from APsmart
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:
· 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 APsmart RSD-S-PLC.
