1 GE Grid Solutions UR Family IP20 Cover Installation Instructions GE Publication Number: GEK C GE Part Number: A4 Copyright 2016 GE Multilin Inc. This document outlines how to install the IP20 protection cover on a GE Universal Relay (UR) device to yield an IP20 safety rating. Introduction The IP20 cover minimizes potential danger to users by covering electrical wires at the back of a UR device. It prevents finger contact with the electrical connections. It meets international enclosure rating standards to the IP20 level. The IP20 kit is an optional accessory sold with UR products. It includes brackets, cable ties, Lexan covers, and screws. There are two variants and use depends on the number of slots on the rear of the UR chassis, either six or seven. Six slots C30, C60, C70, D30, D60, F35, F60, G30, G60, M60, N60, T35, T60 Seven slots B30, B90, L30, L60, L90 The following figures show examples of six and seven-slot devices.

2 Figure 2: Seven-slot UR device rear view The intent of the cover is to improve in-field use to reduce the likelihood of exposure to potential danger. The user is responsible for operating the equipment with caution and within end-product specifications. If parts are missing or defective, do not substitute others. Contact GE technical support. Dimensions The following figure shows the dimensions of the IP20 cover. Figure 3: Dimensions in inches (centimeters) 2 IP20 COVER - INSTALLATION INSTRUCTIONS

3 Unpack and inspect The table outlines the contents of the kits. The two kits differ by the top and bottom brackets. The brackets are identifiable by part numbers, which are printed on the parts.

The process is as follows: Install the IP20 bottom bracket Wire the UR device Install the IP20 top bracket Install Lexan covers All sources must be de-energized when installing the UR device and cover kit. Any attempt to install equipment with live sources can result in permanent injury or death. To install the IP20 cover: 1. Install the bottom bracket as follows. With power off, at the back of the UR device, remove the bottom three screws that line up with the bracket from the module cover plate. Do not remove any other screws.

Apply a torque of 11 inch-pounds when tightening the screws. When attaching the cover, do not substitute screws longer than those provided with the cover, else damage to the boards and erroneous communication can occur. Figure 6: Attach bottom bracket 3. With power off and following instructions in the applicable instruction manual, connect the wires to the back of the UR device. GE recommends using 90 lags instead of flat lag connectors to facilitate organization of the wires through the IP20 cover. 4 IP20 COVER - INSTALLATION INSTRUCTIONS

Install them with 14 covers at the rear, three on one side, and three on the other side. Apply a torque of 10 inch-pounds when tightening the screws. When organizing the wires between the Lexan covers, options are to guide them between the Lexan covers at the back (see photo) or to secure them with the cable ties at the top and bottom of the bracket (see following figure).
