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.
• Plug & play, no configuration required Transmitter: RSS Transmitter • Rapid Shutdown System Transmitter for rapid shutdown activation of TS4-F, TS4-R-F, or TS4-A-F units • The external device that provides a keep- alive signal to the TS4-F via Power Line Communication...
TS4 FIRE SAFETY PRODUCTS Module-Integrated: TS4-F • Module electronics are contained in the junction box, installed at the PV module factory. • Connected in series like regular modules • No additional wiring connections to make Add-on/Retrofit: TS4-R-F, TS4-A-F • Bracket clips to module frame without tools •...
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.
4 - 123A Transmitter Note: connect modules to TS4-R inputs before connecting outputs The TS4-R-F requires a Tigo RSS Transmitter or inverter with built-in transmitter for operation. • TS4-R-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.
UNDER LOAD Transmitter 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.
INSTALLATION NOTES • TS4-F, TS4-R-F, and TS4-A-F are shipped in the OFF position and will measure 0.6V at the output when the keep-alive signal is not present. • Failing to follow the sequence of installation steps may result in TS4 damage not covered under warranty.
TS4-F INSTALLATION Smart modules with an integrated TS4 Junction box are installed and connected in series just like standard PV modules. Connect modules with TS4-F in series before powering on the RSS Transmitter. TS4-F TS4-F 4 - 123A 4 - 123A...
TS4-R-F INSTALLATION Standard modules can be equipped with TS4-R-F add-on/retrofit units as shown below. Always connect modules to TS4-R inputs before connecting outputs. Each TS4-R-F must have a PV module connected to its input before connecting the outputs of TS4-R-F units in series. To disconnect TS4-R-F from a module, disconnect the TS4-R-F outputs from the string before disconnecting the TS4-R-F inputs from the module junction box.
To disconnect TS4-A-F from a module, disconnect the TS4-A-F outputs from the string before disconnecting the TS4-A-F inputs from the module junction box. Tigo Rapid Shutdown Tigo Rapid Shutdown NEC 690.12-2017 and C22.1-2015 Rule 64.218 NEC 690.12-2017 and C22.1-2015 Rule 64.218...

TESTING RAPID SHUTDOWN TS4-F (or TS4-R-F / TS4-A-F) and an RSS Transmitter are a solution to meet NEC 2014 & 2017 690.12 Rapid Shutdown requirements. TS4-F, TS4-R-F, and TS4-A-F 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.
