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 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.
