Any reduction to the diameter of the bend loop for the cable will reduce the efficiency of the cable system, and create additional drag and friction within the cable conduit. IMPORTANT: Verify that the cable assembly does not interfere with any mechanical and moving parts. Keep the cable conduit a minimum of 1/2" from all heat sources and current carrying terminals, fuses, transformers, etc. 1 Disconnect Switch Installation B Panel Mounting Dimensions Switch Size AA BB CC DD EE (4) Mounting Plate Holes FF Minimum Bend Diameter 400A 2" 11" 4-3/4" 1-3/8" 9/32" Dia. 16" Dia. 1a Locate switch with right hand mechanism AA EE AA EE C BB BB DD DD CC CC FF FF D Enclosure with Left Hand Flange Enclosure with Right Hand Flange 1b Locate switch with left hand mechanism AA E AA EE BB EE BB DD DD CC CC FF FF Enclosure with Right Hand Flange F Enclosure with Left Hand Flange (2) G REFERENCE REVISION AUTHORIZATION 1 1026760 2 1030857 BULLETIN 1494C (400A) CABLE OPERATED DISCONNECT SWITCH KIT INSTALLATION INSTRUCTION SHEET DIMENSIONS APPLY BEFORE SURFACE TREATMENT (DIMENSIONS IN INCHES) TOLERANCES UNLESS OTHERWISE SPECIFIED .XX: N/A .XXX: N/A E - DOC THIS DRAWING IS THE PROPERTY OF ROCKWELL AUTOMATION, INC.
