Tigo TS4-F Datasheet

TS4-F Installation Quick Start Guide
· Note: When installing TS4-R-F, connect the input cables to the PV module before connecting
the TS4-R-F output cables in series.
· If disconnecting TS4-R-F, disconnect the TS4-R-F output cables from the string before disconnecting
the input cables from the PV module.
·RSS transmitter must be powered off during TS4-F or TS4-R-F installation.

· Drill holes in enclosure for conduit (see drilling guide for placement)
· Mount RSS Transmitter and power supply on DIN rail
· Connect DC leads from power supply (1) to transmitter (2)
· Connect RSS Core (3) to transmitter
Note: Install TS4-F before powering on RSS Transmitter
Transmitter power supply must be on same AC branch circuit as inverter
to meet rapid shutdown requirements.

· Connect AC and DC ground wires to DIN rail
· Ground all conduit connections
· Turn on AC power to Transmitter power supply to activate
keep-alive signal and energize PV array

TS4-F/TS4-R-F:
·Output voltage without active transmitter signal is 0.6V
·Output voltage with active transmitter signal will be normal
module VMP or VOC
·If output is 0V contact Tigo support
Check that the system conforms to the design rules
for TS4-F:
·Up to 10 strings per RSS Core (CT)
·Up to 30 modules per string
·String length up to 1000ft (total cable length from +to -)
·Homeruns through RSS Core must be the same polarity
(all positive or all negative)
RSS Transmitter:
·Power LED should be lit and Signal LED should be blinking
during operation
·Verify that RSS Core wiring is correct
·Power cycle RSS Transmitter if Signal LED is unlit
·While RSS Transmitter is powered off, string voltage should be
(0.6V * number of modules)
·While RSS Transmitter is powered on, full string voltage should
be present
Test individual strings with active RSS Transmitter
one at a time in case of unexpected voltage.
