TS4-F RAPID SHUTDOWN SYSTEM Tigo’s TS4-F (or TS4-A-F, TS4-A-2F) and RSS Transmitter are a UL-certified PVRSS (Photovoltaic Rapid Shutdown System) when installed together. The RSS Transmitter supplies a keep-alive signal along one of the DC homeruns of the string and the TS4-F units on each module will shut down when the Transmitter is switched off. The TS4-F, TS4-A-F and TS4-A-2F can be used interchangeably in the same system. Module-Level Power Electronics: TS4-F • NEC 2017 and 2020 690.

INSTALLATION NOTES • TS4-F, TS4-A-F, and TS4-A-2F 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-A-F or TS4-A-2F units to their respective modules before connecting their outputs in series. • Install all TS4-F, TS4-A-F, or TS4-A-2F 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. 1 TS4-F 4 - 123A TS4-F 4 - 123A 2 TS4-F 4 - 123A TS4-F 4 - 123A RSS Transmitter must be powered OFF during TS4-F installation.
TS4-A-F INSTALLATION Standard modules can be equipped with TS4-A-F add-on 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.
TS4-A-2F INSTALLATION Standard modules can be equipped with TS4-A-2F add-on units as shown below. Always connect modules to TS4-A inputs before connecting outputs. Each TS4-A-2F must have a PV module connected to its inputs before connecting the outputs of TS4-A-2F units in series. To disconnect TS4-A-2F from a module, disconnect the TS4-A-2F outputs from the string before disconnecting the TS4-A-2F inputs from the module junction box.
PV CONDUCTOR INSTALLATION - MULTI-TRANSMITTER SYSTEMS REQUIRED PRACTICES When installing a system with 2 or more transmitters it is mandatory to use the following best installation practices of PLC circuits to ensure a troublefree installation. Run +/- string conductors from the same transmitter together in the same conduit. >8” (20cm) Run +/- string conductors from the same string together through array and conduit. The closer the conduit or cable tray the greater potential for crosstalk to occur.
MAINTAIN SIGNAL INTEGRITY The following practices will help maintain signal integrity for all PLC rapid shutdown systems. In order to maintain signal integrity, the RSS Transmitter has a specified maximum round-trip distance from positive to negative of 300m (985ft). If the longest string in a system exceeds 300m, but is less than 500m, two cores may be used in series on the string to amplify the signal. Contact Tigo Sales Engineers for more information and assistance in these applications.

TESTING RAPID SHUTDOWN TS4-F (or TS4-A-F, TS4-A-2F) and an RSS Transmitter are a solution to meet NEC 2017 & 2020 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. Wait 30 seconds after rapid shutdown activation before disconnecting DC cables or turning off DC disconnect.
