Crouse-Hinds RE21-SA to reduce to 1/2 inch hubs )
2 Secure the enclosure to the conduit system If the enclosure has mounting feet, select a mounting location that will
provide sufficient strength and rigidity to support the enclosure as well as the enclosed device and wiring
SELECT A MOUNTING LOCATION SO THAT THE ENCLOSURE WILL NOT BE SUBJECTED TO IMPACT BY HEAVY OBJECTS.
IMPACTS CAN DAMAGE ENCLOSED DEVICES OR GLASS LENS.
3 Install Cooper Crouse-Hinds EYS sealing fittings required by Section 501-5 and/or 502-5 of the National Electrical Code and
Section 18 of the Canadian Electrical Code or any other applicable local codes and when enclosure is installed in Class I
Group B hazardous locations (For CSA Group C applications, unsealed conduit lengths must not exceed

instrument or power supply if servicing is required Install instrument and power supply, if applicable, and make all
electrical connections
OTEE: N When installing device, be sure to check instrument dimensions to avoid interference with clamping ring on glass
lens and the cover on standard units
6 Test wiring for correctness by checking continuity and also check for unwanted grounds with insulator resistance tester
Make sure test equipment being used will not damage instrument to be housed in the EIH Instrument enclosure
