Tigo TS4-A-O Quick Start Manual

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.
• To reduce risk of fire 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 (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.
• Risk of electric shock: do not disassemble, or repair. There are no user serviceable parts inside. Refer servicing to qualified service
personnel.
• 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.
• 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.
• 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.
• All equipment shall be installed and operated in an environment within the ratings and limitations of the equipment as published in the
installation manual.
• Trained professionals must perform installation only. Tigo does not assume liability for loss or damage resulting from improper
handling, installation, or misuse of products.
• Always connect short input cables before connecting long put output cables. Failre to do so may void warranty.
System Layout
CCA TAP
• The Cloud Connect Advanced (CCA) logger/gateway connects to the cloud via Ethernet or WiFi and to devices via Modbus.
• The CCA has a wired connection to the Tigo Access Point (TAP).
• The TAP communicates wirelessly with TS4-A-O/S/M MLPE via a mesh network.
TS4 Mounting Options
For frameless modules, use M8 bolts torqued to 10.2Nm.

TS4s
• If frame thickness is ≤35mm (1.4in), install with
the TS4 label facing the PV module.
• No portion of the TS4 may be ≤12.7mm (.5in)
from the module substrate.
• Check PV module instructions for restrictions on
mounting devices under the module.
pages for comprehensive videos, articles,
• All TS4 versions ship in the ON state. Use caution when connecting the units to the modules.
• Disconnect TS4s from the array string before disconnecting from a solar module.
• Each TS4 has an IP68 protection rating but only after properly installed.
• Do not leave TS4 connectors exposed to the rain. Water intrusion may damage the TS4.
• Connectors from different manufacturers cannot be mated with each other.
• TS4s must not be installed in readily accessible locations.
• (TS4-A-O) Operating temperature range -40 – 70 °C (-40 – 158 °F)
• (TS4-A-S/M) Operating temperature range -40 – 75 °C (-40 – 167 °F)
Install TS4s
1. Save the QR/barcode sticker on a site map or string list.
2. Attach the TS4 to the top of the PV module frame.
If frame thickness is ≤35mm (1.4in), install with the TS4 label facing the PV module.
3. Connect the short input cables to the PV module.
4. Connect the long output leads to the adjacent TS4.
