EV2IH EXPLOSIONPROOF PHOTOCELL INSTALLATION …

1 1. Check that the line voltage and the rating of the PHOTOCELL are the same. See table below. When installing the EV2IH Series remote PHOTOCELL cover, location of thecell is important. The photo-sensitive window should preferably be aimedfacing north where the change in light intensity is relatively of trees, close buildings and overhangs may affect the turn offlevels of the PHOTOCELL . If the cell is located near other light sources, thecontrolled light might cycle on and off or not turn on at night. In thesecases, the cell must be repositioned away from all light : The EV2IH Series PHOTOCELL has a built-in-time delay of 10seconds. At night, the fixture will take 10 seconds to be switched on afterpower is supplied. The time delay will prevent nuisance trippings due toexternal light sources at night or shadows during the EXPLOSIONPROOF PHOTOCELLINSTALLATION INSTRUCTIONS AND MAINTENANCE INFORMATIONSAVE THESE INSTRUCTIONS FOR FUTURE REFERENCEIF 1308 Cooper Industries 1308 Crouse-Hinds DivisionRev4PO Box 4999, Syracuse, New York 13221 01/09 Copyright 2008, Cooper Industries, 1 All statements, technical information and recommendations contained herein are based on information and tests we believe to be reliable.

It is recommended that inspections should be performed at least once a Visually check for damaged parts, undue heating evidenced by discoloration of wires or other components, leakage evidenced by wateror corrosion in the interior and proper lamp The PHOTOCELL window and the EV2IH glass cover must be clear in order to work properly. To clean, wipe with a clean damp cloth. Ifthis is not sufficient, use a mild soap or liquid non-abrasive cleaner which will not scratch the disconnect primary power source before openingfixture for inspection or cont d8.
