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.
• All equipment shall be installed and operated in an environment within the ratings and limitations of the
equipment as published in the installation manual.
• 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 and the output voltage may be as high as the PV module open
circuit voltage (V
OC
) 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.
• 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.
• 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.
• Mating connectors from different manufacturers cannot be mated with each other.
The transmitter control power supply MUST be on the same AC branch circuit as the inverter to meet rapid
shutdown requirements.

WARNING - THIS PHOTOVOLTAIC RAPID SHUTDOWN EQUIPMENT (PVRSE) DOES NOT PERFORM ALL
OF THE FUNCTIONS OF A COMPLETE PHOTOVOLTAIC RAPID SHUTDOWN SYSTEM (PVRSS). THIS PVRSE
MUST BE INSTALLED WITH OTHER EQUIPMENT TO FORM A COMPLETE PVRSS THAT MEETS THE
REQUIREMENTS OF NEC (NFPA 70) SECTION 690.12 FOR CONTROLLED CONDUCTORS OUTSIDE THE
ARRAY. OTHER EQUIPMENT INSTALLED IN OR ON THIS PV SYSTEM MAY ADVERSELY AFFECT THE
OPERATION OF THE PVRSS. IT IS THE RESPONSIBILITY OF THE INSTALLER TO ENSURE THAT THE
COMPLETED PV SYSTEM MEETS THE RAPID SHUTDOWN FUNCTIONAL REQUIREMENTS. THIS EQUIPMENT
MUST BE INSTALLED ACCORDING TO THE MANUFACTURER’S INSTALLATION INSTRUCTIONS.
