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 Energy® 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 (V ) when connected to the module.
Plug & play, no configuration required • Transmitter: RSS Transmitter Rapid Shutdown System transmitter for • rapid shutdown activation of TS4-F or TS4-R-F units The external device that provides a • keep-alive signal to the PVRSE device via Power Line Communication.
1.2 TS4 FIRE SAFETY PRODUCTS • NEC 2017 690.12 Rapid shutdown compliant • Module-level deactivation • PLC SunSpec-compliant communication • Plug & play, no configuration required TS4-F Module electronics are contained in the • junction box, installed at the PV module factory.
Method of Operation TS4-F and TS4-R-F units start in the OFF position and measure 0.6V at the output. When power is supplied to the RSS Transmitter, the TS4-F/TS4-R-F units turn ON and allow full PV module voltage.
1.3.2 SYSTEM OVERVIEW: TS4-R-F TS4-R-F Smart Module Add-on Powered by Tigo RSS Transmitter Inverter Note: connect modules to TS4-R inputs before connecting outputs TS4-R mounting is recommended on the upper right as shown, but can be • placed on upper left if needed (due to racking constraints, etc.) TS4-R cable glands must not be facing up.
If parallel string connections are needed, first connect the TS4-F/TS4-R-F to • the PV modules, then connect all TS4-F/TS4-R-F outputs in series, and finally pass one side (+ or -) of the homeruns through the PLC transmitter to turn the system ON.
2.2 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.
2.3 TS4-R-F INSTALLATION Mount the TS4-R-F on Connect the PV the top right corner cables from the of a PV module module to the short leads of the TS4-R-F Connect the long output cables of the TS4-R-F units in series to form strings, as you would with standard PV modules Standard modules can be equipped with TS4-R-F add-on/retrofit...

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