!ATTENTION - READ FIRST
!Wear and USE appropriate PPE for the application.
!Install the TS4-A-F, and/or TS4-A-2F BEFORE powering on the RSS transmitter. All PV
modules from the same inverter must have a TS4 connected.
1. MOUNT 2. Connect MODULES to TS4s 3. Connect the TS4s
!Energy is supplied to the Tigo TS4 output cables immediately upon connection to a PV
module exposed to sunlight. Use care when handling. Do not mate connectors from
different manufacturers.
!Each module in the PV system must contain a TS4-A-F or TS4-A-2F for safe and proper
operation of the PV system.
1. This document is for quick guidance only. For details, please refer to
the TS4-A-F/-2F Installation Manual.
2. Damage caused by failure to follow the contents of the TS4-A-F/-2F
Installation manual is not covered by the warranty.
3. Install all TS4-A-F, and/or TS4-A-2F BEFORE powering on the RSS
transmitter.
4. TS4-A-F, TS4-A-2F and a Tigo RSS Transmitter are a solution to meet
NEC 2017 & 2020 690.12 Rapid Shutdown requirements. TS4-A-F and
TS4-A-2F units automatically enter rapid shutdown mode when the
RSS Transmitter is switched off, and resumes energy production when
power is restored to the RSS Transmitter. Wait 30 seconds after rapid
shutdown activation before disconnecting DC cables or turning off DC
disconnect.

Mounting the TS4 to the PV module frame and dressing the input conductors BEFORE taking the module to
the roof helps save time.
Many leading inverters integrate the Tigo RSS Transmitter. Look for the Tigo Enhanced label or check for Tigo

3. Commissioning
!Wear and USE appropriate PPE for the application. Suggestions: gloves, sunscreen,….
!Wear and USE appropriate PPE for the application. Live voltages may be present.
1. Each PV string will produce less than 30VDC until the RSS Transmitter is activated/powered.
2. When power is provided to the RSS Transmitter the PV strings will produce full voltage under the
environmental conditions.
3. Commission the PV system as per best practice.
3.1 Pre-commissioning checklist
3.2 Commissioning notes
Issue Check
No string voltage Check that all string connectors are securely connected.
Lower voltage than
expected
Check that all PV module connectors are securely connected.
Note – with no keep-alive signal the string voltage will less than 30VDC.
Check that the RSS transmitter is powered on. If multiple transmitters are used, check that all
are of the Pure Signal Technology (PST) series and are properly wired.
Inconsistent
voltage reading
when no signal is
present
1. Apply power to the RSS Transmitter
2. Use an RSS Signal Detector to determine if the individual TS4s are receiving the keep
alive signal. If so, check the string is less than 300m.

Check Item Acceptance Criteria
TS4 installation All PV modules are connected to a TS4-A-F/TS4-A-2F.
Tigo RSS
Transmitter/PST
The Tigo RSS Transmitter is installed per the RSS Transmitter Installation Manual. If
inverter integrated, follow the inverter manufacturer’s instructions for signal/power.
Voltage check
The TS4-A-2F passes 0.6VDC at the output to the string.
String voltage = 0.6VDC x # TS4s in the system.
If TS4-A-F are also used in the same string, add 0.6V for each additional TS4-A-F.
Connections All connectors are securely mated and of same type.
Wire Management
All conductors are properly secured throughout the array. ANSI/NFPA 70 wiring methods
used. Multi transmitter systems have PST transmitters installed and properly wired. Refer
to RSS Transmitter Installation manual for details.
Workmanship Wire management and general best practices were used.
