Rapid Shutdown Kit - Installation and Configuration
(Single Phase Inverters)
This document describes how to install the rapid shutdown kit in the SolarEdge Safety Switch,and how to enable the rapid
shutdown feature in the inverter in order to provide the functionality described in the Rapid Shutdown clause of NEC2014
690.12(1)through(4).
Kit Contents
' Rapid shutdown cables
' Micro-SD card and SD card adapter with firmware files(Note:DO NOT THROWAWAY THE CARD AND THE ADAPTER; keep
them for installation of other rapid shutdown kits)
Cable Installation
Perform this procedure before connecting the strings to the Safety Switch [Chapter 4:Connecting the AC and the Strings to the
Safety Switch in the SolarEdge Installation Guide].
1 Turn the inverter ON/OFF switch to OFF.If installing the kit in an inverter that is already operating,wait until the LCD
indicates that the DC voltage is safe(<50V),or wait five minutes before continuing to the next step.
2 Turn the Safety Switch and the AC switch on the main circuit board to OFF.
! If you cannot see the inverter panel,or if a malfunction is indicated on the LCD panel,wait five minutes for the input
capacitors of the inverter to discharge.
3 Loosen the four Allen screws on the front cover of the Safety Switch,and open the cover.
4 Carefully disconnect the two DC cables from the left side of the switch and from the DC connection spring clamp terminals,
as illustrated below'.Use a standard straight-bladed screwdriver to disconnect the cables from the terminals.

Inverter Software Compatibility Check and Upgrade
Perform this procedure after activating the inverter[Step 1 in Chapter 5:Commissioning the Installation of the SolorEdge
Installation Guide],and before pairing(Step 2 in Chapter 5 of the SolorEdge Installation Guide).
To use the rapid shutdown feature,the inverter communication board firmware(CPU)must be:
• Version 2.0700 or higher,if the CPU version is 2.Oxxx
• Version 3.0700 or higher,if the CPU version is 3.Oxxx
® To check the inverter CPU version:
1 Verify that the inverter has been activated using the activation card supplied with the inverter.
2 Press the LCD light buffo_n short presses until the screen below is reached.

3 Check the CPU version number.If lower than 2.0700,upgrade the inverter software as described below;otherwise proceed
to"Power Optimizer Pairing".
10, To upgrade the inverter software:
Use the supplied SO card adapter or the micro-SD card,which can be removed from the adapter,according to the activation
card slot on your inverter communication board,labeled E G110 .
7 Verity that the AC breaker connected to the inverter is OFF.
2 Open the inverter cover's six Allen screws and carefully pull the cover horizontally before lowering it, as described In its
manual.
3 Insert the card into the card slot on the communication board. If the communication board has an SD card slot,use the
supplied SO card adapter.If there is a micro-SD card slot,remove the micro-SD card from the adaptor and insert it.
4 Close the inverter cover and turn the AC on.If upgrade is required(as described above),it starts automatically.
5 Wait for the message"Done"to be displayed on the LCD.
6 Verify the correct version as described above.
7 Remove the card from the inverter and keep it for additional kit installations.
Power Optimizer Pairing
Pairing at this stage will reprogram the power optimizers to perform rapid shutdown.
1 Verity that the ON/OFF switch at the bottom of the inverter is OFF.
2 Turn ON the AC breaker and the Safety Switch.
3 Perform Pairing as described in Step 2:Pairing,of Chapter 5:Commissioning of the SolorEdge Installation Guide.
Enabling Rapid Shutdown
There is an option in setup mode to enable the functionality of rapid shutdown.
1 Verify that the ON/OFF switch at the bottom of the inverter is ON.
2 Enter Setup mode by pressing and holding the LCD light button.
