Control Devices EFS, EFD and EDS SeriesInstallation & Maintenance Information SAVE THESE INSTRUCTIONS FOR FUTURE REFERENCEIF 899APPLICATIONEFS and EDS Series Control Devices are used in conjunction with magnetic starters or contactors forremote control of motors and to visually indicate that the desired function is being performed. EFD Se-ries Manual Motor Starting Switch Enclosures are used for manually starting or stopping small AC or DCmotors. EFD Series Circuit Breakers provide overload protection to the load side conductors.EFS/EDS (dead end) and EFSC/EDSC (through feed) Series Pushbutton Stations, Selector Switches andFactory Sealed Pilot Lights are used separately or in combination with a variety of standard features andspecial options available.EFS Series Control Devices are suitable for use in Class I, Groups B, C, D (Division 1), Class II, Groups E,F, G, and Class Ill hazardous (classified) locations, as defined by the National Electrical Code® (NEC) andCanadian Electrical Code (CEC). EDS and EFD Series Control Devices are suitable forClass I, Group B (Division 1) usage when they are identified by the suffix GB added to the catalog numberwith seals immediately adjacent to each conduit opening.DSD Series Control Device Covers are suitable for Class I,Groups B (Division 2 only), C, D and Class II, Groups E, F,G as standard.The XT suffix provides an expanded temperature rangeof -50°C to +60°C for EDS and EFS Assemblies, DSDand DS Covers and FlexStation™ Components. For ironassemblies, only EDS iron back boxes externally markedwith an “X” on the conduit hub can be assembled with XTsuffix iron covers. All aluminum back boxes (no marking)may be assembled with XT suffix aluminum covers. XTsuffix covers can only be used with single gang back boxes and cannot be used with the GB suffix. Theconduit sealing requirements are displayed in Conduit Seal Requirements Chart.INSTALLATION1. Select a mounting location that will provide suitable strength and rigidity for supporting allcontained wiring and control devices. Figure 2 shows the mounting dimensions of all EFS, EFDand EDS Device Bodies. Drill and tap mounting holes for 5/16 - 18 bolts.2. Securely fasten the device body to the mounting surface, then attach the body into the conduitsystem.3. Pull supply wires into the enclosure, making them just long enough to make the requiredconnections.4. Make the electrical connections utilizing the wiring scheme established for your system. SeeFigures 1A and 1B for the contact diagrams of EFS and EDS Pushbutton Stations and SelectorSwitches.Figure 1AFigure 1BPILOT LIGHTSFigure 1CThe field wiring terminals on the switch units used for pushbutton or selector switch stations are marked.The and “0” indicate normally open contacts; and and “C” indicate normally closed contacts ofthe switch. These switches are provided with binding screw terminals. For EDS/EDSC Series ToggleSwitches: splice factory sealed wires to supply wires using suitable connectors.• Strip the insulation on each conductor wire back 3/8”.• Use a slotted or Phillips head screwdriver to loosen the field wiring terminal screws the requiredthree (3) or four (4) turns.• Insert the bare wire conductor(s) on either side of the terminal screw(s), under the terminal wireclamp(s) and securely tighten the screw(s).NOTE: Do not exceed 15 in.-lbs. of torque.• Pilot lights and sealing wells are furnished with pigtail leads for field connection by use of wirenuts.• For EFD Manual Motor Starters, install heaters as required. Refer to manufacturer’s heaterselector listings for each motor starting switch. Mount the starter into enclosure and makeelectrical connections utilizing the wiring scheme established for the motor starting switch.5. Test wiring for correctness with continuity checks and also for unwanted grounds with an insulationresistance tester.6. Select the proper cover for assembly. Similar cover and back box materials can only be used (e.g.iron with iron; aluminum with aluminum). Assemble cover to the device body with the coverscrews. Check the tightness of the cover screws to ensure that the cover assembly is securelyfastened.7. Pour Chico® Sealing Compound into EYS/EYD Series Sealing Fittings (where used) in accordancewith the instructions with each sealing fitting used.NOTE: Seals are not required for Class I, Division 2.PILOT LAMP REPLACEMENT110-125 Volt Circuit: 6 watt, T21/2 miniature bayonet baseLED Replacement: 24, 120 VAC, T31/4 miniature bayonet baseMAINTENANCE1. Frequent inspection should be made. A schedule for maintenance checks should be determined bythe environment and frequency of use. It is recommended that it should be at least once a year.2. Perform visual, electrical and mechanical checks on all components on a regular basis.Visually check for undue heating evidenced by discoloration of wires or other components,damaged or worn parts or leakage evidenced by water or corrosion in the interior.Electrically check to make sure that all connections are clean and tight, and that contacts in thecomponents make or break as required.Mechanically check that all parts are properly assembled, and that operating mechanisms movefreely.Figure 2! CAUTIONHammers or prying tools must not be allowed to damage the flat ground joint surfaces. Do nothandle covers roughly or place them on surfaces that might damage or scratch the flat ground jointsurfaces.! CAUTIONHazardous location information indicating the class and group the product is approved for is markedon the nameplate of each device. Conduit sealing fittings may be required to be installed to complywith the requirements of the latest edition of the CEC or NEC, Section 501-5 and/or 502-5, plus anyother applicable standards. Review nameplate for specific information.! WARNINGElectrical power must be OFF before and during installation and maintenance.! WARNINGNo conduit openings are to be added in the field. All unused conduit openings must be pluggedand plugs must be a minimum of 1/8 inch thick and have a minimum of five (5) threads engagement(seven (7) threads for Group B applications). For EFS Enclosures with 1 inch hub(s), EDS 3-pole SnapSwitches and EFD/EDS with “GB” suffix, all conduits must be sealed within 18 in. of the enclosure.! WARNINGCheck for dirt, grit or other foreign material on the mating surfaces of the cover and the device body.Be certain that each surface is wiped completely clean before assembling. Surfaces must seat fullyagainst each other to provide a proper explosionproof seal.!
