IMPORTANT SAFETY INSTRUCTIONS
2
• This manual contains important instructions for installation and maintenance of the Tigo
product models TS4-F, TS4-A-F, TS4-A-2F, and the RSS Transmitter.
• Risk of electric shock, do not remove cover, disassemble, or repair, no user serviceable
parts inside. Refer servicing to qualied service personnel.
• Before installing or using the Tigo System, please read all instructions and warning
markings on the Tigo products, appropriate sections of your inverter manual,
photovoltaic (PV) module installation manual, and other available safety guides.
• Failure to adhere to these instructions may result in injury or death, damage to the
system or voiding the factory warranty.
• To reduce risk of re and shock hazard, install this device with strict adherence to
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. The installer
should use the same caution when handling electrical cables from a PV module with or
without the TS4 units attached.
• Installation must be performed by trained professionals only. Tigo does not assume
liability for loss or damage resulting from improper handling, installation, or misuse of
products.
• Remove all metallic jewelry prior to installing the Tigo TS4 units to reduce the risk of
contacting live circuitry. Do not attempt to install in inclement weather.
• Do not operate the Tigo TS4 units if they have been physically damaged. Check existing
cables and connectors, ensuring they are in good condition and appropriate in rating.
Do not operate Tigo TS4 units with damaged or substandard wiring or connectors. Tigo
TS4 units must be mounted on the high end of the PV module backsheet or racking
system, and in any case above ground.
• Do not connect or disconnect under load. Turning off the Inverter and/or the Tigo
products may not reduce this risk. Internal capacitors within the inverter can remain
charged for several minutes after disconnecting all power sources. Verify capacitors
have discharged by measuring voltage across inverter terminals prior to disconnecting
wiring if service is required. Wait 30 seconds after rapid shutdown activation before
disconnecting DC cables or turning off DC disconnect.
• Always assume TS4 units are in “ON” state, or may turn on when restarting.
The transmitter control power supply MUST be on the same AC branch circuit
as the inverter to meet rapid shutdown requirements.
LETHAL VOLTAGE MAY BE PRESENT IN ANY PV INSTALLATION

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. When
power is supplied to the RSS Transmitter, the TS4-F units turn ON and allow full
PV module voltage.
The units constantly receive a “keep-alive” signal from the transmitter over
PLC. When power to the transmitter is cut, this keep-alive signal ceases,
sending every TS4-F into shutdown mode with output reduced to 0.6V.

INSTALLATION NOTES
•TS4-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-A-F units to their respective modules
before connecting their outputs in series.
•Install all TS4-F or TS4-A-F/TS4-A-2F units before powering
on the RSS Transmitter.
• Never apply an external voltage source to a module or string
equipped with TS4-F or TS4-A-F/TS4-A-2F units.
•If parallel string connections are needed, first connect the TS4-F
or TS4-A-F to the PV modules, then connect all TS4-F or TS4-A-F
outputs in series, and finally pass one side (+ or -) of the homeruns
through the PLC transmitter to turn the system ON.
•If connecting TS4-A-2F to a single PV module:
•Connect PV module to Input 1, connect Input 2 cables together
•Place rapid shutdown system label no more than 1m (3ft) from
initiator (AC disconnect) or service panel containing means of
disconnection if not at same location.
