TS4-F RAPID SHUTDOWN SYSTEM Module-Level Power Electronics: TS4-F, TS4-R-F, TS4-A-F • NEC 2017 690.
TS4 FIRE SAFETY PRODUCTS Module-Integrated: TS4-F • Module electronics are contained in the junction box, installed at the PV module factory.
SYSTEM OVERVIEW: TS4-F 1 2 3 RSS Transmitter 1. Modules with integrated TS4-F 2. RSS Transmitter and RSS Core 3. Inverter 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. Method of Operation All TS4-F units start in the OFF position and measure 0.6V at the output.
SYSTEM OVERVIEW: TS4-R-F 1 2 3 TS4-R-F 4 - 123A RSS 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. • TS4-R-F cable glands must not be facing up. • Allow clearance between PV module and mounting surface for air circulation around TS4-R-F.
SYSTEM OVERVIEW: TS4-A-F 1 2 3 Tigo Rapid Shutdown NEC 690.12-2017 and C22.1-2015 Rule 64.218 TS4-A-F 4 - 123A DO NOT DISCONNECT UNDER LOAD RSS 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. • TS4-A-F cable glands must not be facing up.
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. • Connect all TS4-R-F or TS4-A-F units to their respective modules before connecting their outputs in series. • Install all TS4-F, TS4-R-F, or TS4-A-F units before powering on the RSS Transmitter.
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-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.
TS4-A-F INSTALLATION Standard modules can be equipped with TS4-A-F add-on/retrofit units as shown below. Always connect modules to TS4-A inputs before connecting outputs. Each TS4-A-F must have a PV module connected to its input before connecting the outputs of TS4-A-F units in series. 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. 1 2 Tigo Rapid Shutdown Tigo Rapid Shutdown NEC 690.

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. Wait 30 seconds after rapid shutdown activation before disconnecting DC cables or turning off DC disconnect.
