Use Adapter plate without studs (item 16) for all other flex shaft cable mechanisms. 2. Use slide arm (item 4) for all AMT below handle mechanisms and AMT flex shaft cable mechanisms. Use slide arm (item 15) only for AMT flex shaft mechanisms for F frame circuit breakers. 2005 Hoffman Enclosures Inc. 2 87569093

INTRODUCTION This installation instruction is for Westinghouse Below Handle AMT and Flex Shaft AMT mechanisms. These mechanisms are for disconnect switches and circuit breakers mounted in Hoffman two door, floor mounted, enclosures with the disconnect on the right flange. Master Door INSTALLATION STEPS Step 1 Install adapter plate (item 1 or 16) and plate gasket (item 2) on the inside of the enclosure, behind the rectangular opening provided. Secure in place with four screws (item 3). Step 2 Assemble the Westinghouse AMTOP operating handle to the mounting plate which was installed in the enclosure in step 1. Omit cap screw and lockwasher which fits into bottom hole of AMTOP operating handle. Step 3 Install the slide arm (item 4 or 15) over the projecting part of the AMTOP operating handle as shown. Note that bottom holes in slide arm are not on center of slide arm. Place the smaller diameter end of the shoulder collar (item 5) through the oval slot in the slide arm. Install long cap screw (item 6) with lockwasher (item 7) through shoulder collar into the bottom mounting hole of the AMTOP operating handle and tighten. The slide arm should move up and down smoothly. Install interlock lever extension per Westinghouse instructions. Step 4 Attach the bottom of the slide arm (item 4 or 15) to the offset arm of the lock release mechanism. Use two flat washers (item 8), two lockwashers (item 9), and two hex nuts (item 10). Do not tighten until parts are adjusted (see step 5B) Step 5 The handle safety lock release mechanism is adjustable in two places. A) Check the adjustment of the factory installed roller bracket. The door latch should hit against the latch stop portion of the roller bracket when the door is closed and latched. Adjust up or down if necessary. The attached mechanism will then provide the necessary up down motion required to operate the release mechanism in the AMTOP operating handle. B) Adjust the length of the slide arm assembly. With proper adjustment of the slide arm, the safety lock (in AMTOP operating handle) should release just before the master door is fully latched. Lengthen slide arm if safety lock releases too soon. Shorten slide arm if safety lock releases too late. Step 6 Attach the cover interblock blade (item 11), provided by Hoffman, to the tapped spacer on the door using the bottom set of mounting holes. Used the two screws (item 12) and lockwashers (item 13). The cover interlock blade prevents the door from being opened when the AMTOP operating handle is in the ON position. This blade may be adjusted up or down to hook properly on the interlock lever extension. The blade (item 11) must be positioned so the bottom edge of blade clears the interlock lever extension by 1/4 inch when AMTOP operating handle is in extreme OFF position. Step 7 Drill and tap holes in panel for disconnect required. See table for location of disconnect centerlines. See Westinghouse instructions for location and size of mounting holes. Step 8 Install panel in enclosure. Step 9 Mount disconnect switch or circuit breaker on panel using Westinghouse instructions and parts. 87569093 2005 Hoffman Enclosures Inc. 3
