IMPORTANT SAFETY INFORMATION
LETHAL VOLTAGE MAY BE PRESENT IN ANY PV INSTALLATION
SAVE THESE INSTRUCTIONS
•  AllPVRSEcomponentsmustbeinstalledandmaintainedbyqualiedpersonnelin
accordance with applicable electrical codes and instructions in the
TS4-A-F/2F with RSS Transmitters Installation Manual.
• Strictly adhere to all ANSI/NFPA 70 (North America) and local electrical codes.
• Improper installation may cause damage not covered by the warranty.
• Do not install TS4s that are physically damaged or have damaged or substandard wiring or connectors.
• Do not connect or disconnect TS4s under load.
• When used as a PVRSS solution, all solar modules in the array must be equipped with TS4-A-F/2F and RSS
transmitter PVRSE. Rapid shutdown is initiated upon AC power loss that stops power to the RSS transmitter.

Install TS4-A-Fs
1. Connect the short input cables to the PV module.
2. Connect the long output leads to the adjacent TS4 to
create a string.
• Always assume that TS4s are in an ON state.
• Ensure cable glands face down and cannot
collect moisture.
• Disconnect TS4s from the array string before
disconnecting from a PV module.
• Always connect short input cables
before connecting long output cables.
Failure to do so may void the warranty.
Install TS4-A-2Fs
If connecting a TS4-A-2F
to only one solar module,
connect the TS4 #2 input
cables to each other.
TS4 Mounting Options For frameless modules, use M8 bolts torqued to 10.2 Nm.

• Check PV module instructions for restrictions on mounting
devices under the module.

• Improper installation may cause damage not covered

electrical code requirements.
The RSS Transmitter
Mount on a 35 mm DIN rail within a NEMA 1 (indoors)
or NEMA 4 (outdoors) enclosure.
• Transmitters must be on the same AC branch circuit as the inverter.
• Connect one standard, 100-240 V 12 V/1 A power supply per transmitter or connect one commercial, 180-
550 V/10 A power supply to up to ten transmitters with parallel connections.

Connect Signal Wiring
• Connect 14 – 22 AWG wires between OUT/Tx and IN/Rx
terminals and between OUT/COM and IN/COM terminals.
• Check that Tx/Rx wires never contact COM terminals.
The maximum length of signal wire between
transmitters is 30.5 mm (100 ft.).
If connected correctly:
• The leader transmitter displays a
continuous red LED and a blinking
green LED.
• Follower transmitter LEDs blink green
simultaneously with no red.
Leader Follower Follower Last follower
Connect a Core
• Insert core wires into matching white/black core
terminals.
• Route up to ten negative PV conductors through a
core.
• The white side of the core must face the inverter.
• Maximum home run length is 300 m (985 ft.).
PV array White side Inverter
• All solar modules in an RSS string must be controlled
by a TS4-A-F or TS4-A-2F device. The rapid shutdown
system (RSS) controls all conductors.
• This RSS must be connected to an automatic system
that initiates rapid shutdown upon the activation of
the AC system disconnect. The RSS transmitter must
be powered from the same power that the rapid
shutdown initiator (RSI) will interrupt in order to
trigger a shutdown of the inverter.
• Rapid shutdown occurs within 30 sec. after an
AC disconnect (inverter or switch) disconnects AC
power to the inverter and RSS transmitter, ceasing
transmission of a keep-alive signal.

• TS4-A-F/2F PV array (DC) conductors are 12 AWG.
• Normal operating temperature range is -30 °C to 70 °C.
• TS4-A-F/2Fs are compatible with the grid support function described in UL 1741 Tables SA9.1 and SA10.1: response to low- and high-voltage ride-
through (L/HVRT) and low- and high-frequency ride-through (L/HFRT) requirements.
• Connectorsfromdierentmanufacturerscannotbematedwitheachother.
• Modules must not be installed in readily accessible locations (Canada only).
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 ADVERSLY AFFECT THE OPERATION OF THE PVRSS. IT IS THE RESPONSIBILITY OF THE INSTALLER TO
ENSURE THAT THE COMPLETED PV SYSTEM MEETS THE RAPID SHUT DOWN FUNCTIONAL REQUIREMENTS. THIS EQUIPMENT MUST BE INSTALLED
ACCORDING TO THE MANUFACTURER’S INSTALLATION INSTRUCTIONS.
In accordance with Section 690.56(C)© of the NEC (NFPA 70), a rapid shutdown system label must be placed no more than 1 m (3 ft.) from the initiator
(AC disconnect) or service panel containing a means of disconnection if not at the same location.
