HARDWIRED SURGE PROTECTION DEVICES SG Modular Series USER MANUAL TRANSIENT SURGE SUPPRESSORS FOR AC POWER PANEL APPLICATIONS R R LISTED LISTED 1449 2nd Edition
GENERAL A.) This document provides detailed information on how to install and operate the SG Modular Series of Surge Protective Devices (SPD). B.) Units should be mounted as close as possible to the AC panel to be protected. It is recommended that conduit, preferably metallic, be utilized to accomplish this connection. C.) The SG Modular Series Protectors are installed and connected in parallel ("shunt") across the AC supply to be protected.
INSTALLATION INSTRUCTIONS Before starting the installation, measure the Line voltage with an AC voltmeter to ensure the correct device has been selected for the current application.
