National Electric Code (NEC) ANSI/NFPA 70 and/or local electrical codes. When the photovoltaic array is exposed to light, it supplies a DC voltage to the Tigo TS4 units. The TS4 units start in the “ON” state and their output voltage may be as high as the PV module open circuit voltage (VOC) when connected to the module.
• Rapid Shutdown System Transmitter for rapid shutdown activation of TS4-F or TS4-A-F units • The external device that provides a keep- alive signal to the TS4-F via Power Line Communication • Integrated in CPS 25/50/60kW Inverter Tigo RSD wire-boxes...

The TS4-F requires a Tigo RSS Transmitter or inverter with built-in transmitter for operation. The Tigo RSS Transmitter is installed in line with a solar PV inverter, as shown, and can be installed inside the inverter or external to it.
Tigo RSD wire-boxes) 3. Inverter Note: connect modules to TS4-A inputs before connecting outputs The TS4-A-F requires a Tigo RSS Transmitter or inverter with built-in transmitter for operation. • TS4-A-F mounting is recommended on the upper right as shown, but can be placed elsewhere on the frame or bolted to the racking if needed.

TESTING RAPID SHUTDOWN TS4-F (or TS4-A-F, TS4-A-2F) and an RSS Transmitter are a solution to meet NEC 2014 & 2017 690.12 Rapid Shutdown requirements. TS4-F, TS4-A-F, and TS4-A-2F units automatically enter rapid shutdown mode when the RSS Transmitter is switched off and resume energy production when power is restored to the RSS Transmitter.
