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 APsystems 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 and on the APsystems microinverter system and the solar array.
· 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 APsystems 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 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 personne:
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 circuits in accordance with established safety procedures. The inverter
and endues system may only be commissioned and operated by qualified personnel.

SYSTEM WIRING DIAGRAM
①RSD-S-PLC
②Transmitter-PLC
③Inverter
The APsmart Rapid Shutdown System (RSS) Transmitter-PLC is part of a rapid shutdown solution
when paired with APsystems RSD-S-PLC, a PV module rapid shutdown unit. While powered on, the
RSS Transmitter 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 RSS Transmitter-PLC is
switched o and resume energy production when power is restored to the RSS Transmitter. This
solution complies with NEC 690.12 specifications for 2017 and supports the SunSpec signaling for
rapid shutdown.

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.
