Product Usage Instructions

Step 1: Install the mounting plate (item 1) and plate gasket (item 2) on the inside of the enclosure, behind the rectangular opening provided. Attach the gasket side with PSA to the adapter plate. Secure in place with four screws (item 3) and four nylon washers (item 14).
Step 2: Discard the ABB spring bracket installed inside the enclosure flange, behind the ABB handle mechanism.
Step 3: Assemble the ABB handle mechanism to the mounting plate installed in step 1. Omit the cap screw and lockwasher that fit into the bottom hole of the handle mechanism.
Step 4: Attach the lock release mechanism to the top of the slide arm (item 4) using a hex head screw (item 6), a spring lockwasher (item 7), and a flat washer (item 8).
Step 5: Attach the bottom of the slide arm (item 4) 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.
Step 6: Adjust the handle safety lock release mechanism in two places to ensure proper operation.
Step 7: Attach the door catch (item 11) provided by Hoffman to the tapped spacer on the door using the bottom set of mounting holes. Use two screws (item 12) and lockwashers (item 13). The door catch prevents the door from being opened when the handle mechanism is in the ON position.

Please note that the functions, fits, and clearances of the installation described in these instructions are calculated based on information supplied by the manufacturers of the equipment to be installed.

INTRODUCTION

This installation instruction is for ABB Variable Depth, Small Handle, mechanisms. These mechanisms are for disconnect switches and circuit breakers mounted in Hoffman two door floor−mounted, Bulletin A21 enclosures with the disconnect on the right flange.

INSTALLATION STEPS

Step 1
Install mounting plate (item1) and plate gasket (item 2) on the inside of the enclosure, behind the rectangular opening provided. Gasket side with PSA should be attached to the adapter plate. Secure in place with four screws (item 3) and four nylon washers (item14).
Step 2
Discard the ABB spring bracket which is normally installed inside the enclosure flange, behind the ABB handle mechanism.
Step 3
Assemble the ABB handle mechanism to the mounting plate which was installed in the enclosure in step 1. Omit cap screw and lockwasher which fits into bottom hole of the handle mechanism.
Step 4
Install the slide arm (item 4) over the defeater part of the handle assembly (on ABB handle mechanism) with notch toward door opening, as shown. 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 ABB handle mechanism and tighten. The slide arm and defeater should move up and down smoothly. Install door hasp (ABB part) per ABB instructions.
Step 5
Attach the bottom of the slide arm (item 4) 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 6B).
Step 6
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 ABB handle mechanism.
B: Adjust the length of the slide arm assembly. With proper adjustment of the slide arm, the safety lock(on ABB handle mechanism) 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 7
Attach the door catch (item 11), provided by Hoffman, to the tapped spacer on the door using the bottom set of mounting holes. Use two screws (item 12) and lockwashers (item 13). The door catch prevents the door from being opened when the handle mechanism is in the “ON” position.
Step 8
Drill and tap holes in panel per ABB instructions. See ABB instructions for locating extra holes for fuse clips.
Step 9
Mount switch or circuit breaker using ABB instructions and parts. ABB connecting rod must be cut off per ABB instructions.

Step 3
Assemble the ABB handle mechanism to the mounting plate which was installed in the enclosure n step 1. Omit cap screw and lockwasher which fits into bottom hole of the handle mechanism.
Step 4
Install the slide arm (item 4) over the defeater part of the handle assembly (on ABB handle mechanism) with notch toward door opening, as shown. 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 ABB handle mechanism and tighten. The slide arm and defeater should move up and down smoothly. Install door hasp (ABB part) per ABB instructions.
Step 5
Attach the bottom of the slide arm (item 4) 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 6B)
Step 6
