Rapid Shutdown Kit Installation - MAN-01-00186-1.6 1 <br />Rapid Shutdown Kit - Installation and Configuration <br />(Single Phase Inverters) <br />This document describes how to install the rapid shutdown kit in the SolarEdge Safety Switch, and how to enable the rapid <br />shutdown feature in the inverter in order to provide the functionality described in the Rapid Shutdown clause of NEC2014 <br />690.12 (1) through (4). <br />Kit Contents <br />ƒ Rapid shutdown cables <br />ƒ Micro-SD card and SD card adapter with firmware files (Note: DO NOT THROW AWAY THE CARD AND THE ADAPTER; keep <br />them for installation of other rapid shutdown kits) <br />Cable Installation <br />Perform this procedure before connecting the strings to the Safety Switch [Chapter 4: Connecting the AC and the Strings to the <br />Safety Switch in the SolarEdge Installation Guide]. <br />1 Turn the inverter ON/OFF switch to OFF. If installing the kit in an inverter that is already operating, wait until the LCD <br />indicates that the DC voltage is safe (<50V), or wait five minutes before continuing to the next step. <br />2 Turn the Safety Switch and the AC switch on the main circuit board to OFF. <br /> <br />WARNING! <br />If you cannot see the inverter panel, or if a malfunction is indicated on the LCD panel, wait five minutes for the input <br />capacitors of the inverter to discharge. <br />3 Loosen the four Allen screws on the front cover of the Safety Switch, and open the cover. <br />4 Carefully disconnect the two DC cables from the left side of the switch and from the DC connection spring clamp terminals, <br />as illustrated below1. Use a standard straight-bladed screwdriver to disconnect the cables from the terminals. <br />Figure 1: Inside the AC/DC Safety Switch <br />1 The internal components may vary depending on the Safety Switch model; the figures in this documents show the AC/DC Safety Switch for single phase <br />7.6-11.4 kW inverters. <br />DC connection terminals <br />Disconnect here <br />Disconnect here <br />Switch terminal block <br />Rapid Shutdown Kit - Installation and Configuration (Single Phase Inverters) <br />Rapid Shutdown Kit Installation - MAN-01-00186-1.6 2 <br />5 The rapid shutdown cables have a resistor connected to one end (on the red cable). Connect these ends to the switch, <br />making sure that the red and black cables are reversed relative to the cables connected at the top of the switch (going into <br />the DC side conduit between the inverter and the Safety Switch), as detailed below. Apply a torque of 2 N*m (18 lb*in): <br />ƒ If the cables at the top are red and black from left to right, connect as shown below. <br /> <br />Figure 2: Rapid shutdown cable connected – option 1 <br />ƒ If the cables at the top are black and red from left to right, connect as shown below. <br />Figure 3: Rapid shutdown cable connected – option 2 <br />6 Use a standard straight-bladed screwdriver to connect the other end of the rapid shutdown cables to the DC connection <br />spring-clamp terminals: Connect the black cable from the switch to the DC- terminal block, and connect the red cable from <br />the switch to the DC+ terminal block. <br />7 Check that the cables are located and connected in the correct positions to ensure the rapid shutdown functionality. <br />8 Close the cover: Attach the switch cover and secure it by tightening the four screws with a torque of 0.9 ft.*lb / 1.2 N*m. <br />Red (+) Black (-) <br />Black (-) <br />DC+ DC- <br />Red (+) with rapid <br />shutdown resistor <br />Black (-) Red (+) <br />Black (-) BlaRed (+) with rapid <br />shutdown resistor <br />DC+ DC- <br />2402 S Rene Dr <br />11/03/22
