Eaton Crouse-Hinds FSQ Series Installation & Maintenance Information

CAUTIONTo avoid fire hazard or accelerated degradation of insulation, usecopper conductors only with an insulation rating of 75º C min. Sizeconductors for 60º C ampacity.5. Pull all branch circuit and ground conductors into enclosure,providing sufficient length to connect to enclosed switch terminals.6. Make electrical connections utilizing the wiring pattern establishedfor your system. Connect branch circuit conductors to enclosedswitch screw terminals with corresponding terminals connectedthrough same conductors attached to receptacle contacts. Connectgreen grounding conductor to receptacle grounding screw.Note: Avoid conductors of excessive length which may crowd the switchcontacts and restrict proper switch operation.Figure 3CAUTIONReceptacle housing must be securely attached into a permanentlygrounded conduit system in accordance with Article 250 of theNational Electrical Code.7. Re-thread cover into housing. Tighten cover until cover flangecontacts body face. Back off slightly to align access hole in loweredge cover with cover locking screw.8. Turn cover locking screw counterclockwise (outward). This will lockcover in place and release the receptacle interior so that the switchcan be operated.9. Test mechanically by aligning and inserting mating plug fully.Rotate plug clockwise as indicated on receptacle plate. Rotatecounterclockwise and withdraw plug.Note: Lockout holes are aligned when in the “OFF” position.10. Unused conduit entries must have plugs installed.WARNINGDo not connect to power until the following electrical tests havebeen performed:• Make continuity check of wiring to verify correct phasing andgrounding connections.• Check insulation resistance to be sure system doesnot have any short circuits or unwanted grounds.WARNINGTo avoid electrical shock always disconnect primary power sourcebefore opening enclosure for inspection or service.WIRING DIAGRAM 1 - (FSQC2390 AND 3390 ONLY)MAINTENANCEElectrical and mechanical inspection of all components must beperformed on a regular schedule determined by the environment andfrequency of use. It is recommended that inspection be performed aminimum of once a year.WARNING1. Inspect switch wire terminals for tightness. Discoloration due toexcessive heat is an indicator of a possible problem and should bethoroughly investigated and repaired as necessary.2. Check grounding and bonding for correct installation and secureconnection.3. Clean exterior surfaces making sure nameplates remain legible.4. Check tightness of all screws before using.5. Inspect housings and replace complete unit for those which arebroken.6. Check contacts for signs of arcing or burning. Discontinue use andreplace complete unit if arcing is evident.In addition to these required maintenance procedures, we recommendan Electrical Preventative Maintenance program as described in theNational Fire Protection Association Bulletin NFPA No. 70B.Terminal Wire Size TorqueSwitch 4 - 8 AWG 50 lb. - in.Ground 2 - 8 AWG 40 lb. - in.Terminal Wire Size TorqueSwitch 10 AWG 20 lb. - in.Ground 8 - 14 AWG 12 lb. - in.FSQ 30 AmpFSQ 60 AmpAll statements, technical information and recommendations contained herein are based on information and tests we believe to be reliable.
