Installation Manual
TS4 UHD-Core with TAP and CCA

IMPORTANT SAFETY INSTRUCTIONS
2
• This manual contains important instructions for installation and maintenance of the Tigo
product models TS4-L, TS4-O, TS4-S, TS4-M, TS4-A-O, TS4-A-O-Duo, TS4-R-O, TS4-R-S, TS4-R-M,
TS4-R-O-Duo, TS4-R-S-Duo, TS4-R-M-Duo, Tigo Access Point (TAP), Cloud Connect
Advanced (CCA), and related Tigo software and mobile applications.
• 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 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 CCA must be on the same AC branch circuit as the inverter to meet shutdown
requirements.
LETHAL VOLTAGE MAY BE PRESENT IN ANY PV INSTALLATION

MESH CONFIGURATION
18
TAP attaches to module frame using
built-in bracket. Mounting holes are
also available in case of frameless
modules.
Place TAP within 10m of any TS4 unit in the
array, with a maximum distance of 10m
between TS4 units and 35m from TAP to
farthest TS4.
33ft (10m) max
Connect multiple TAP units in series and leave terminating resistor in final TAP only.
Use 4-conductor RS485 (18-22 AWG) cable between TAP and CCA.
