INTRODUCTION
This installation instruction is for ABB Cable Controlled Small Handle mechanisms. These mechanisms are for disconnect switches and circuit breakers mounted in Hoffman two door, floor−mounted and one through six door, free−standing enclosures with the disconnect on the right flange.
INSTALLATION STEPS
Step 1
Install adapter plate (item 1) 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 (item 14).
Step 2
Assemble the ABB 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 ABB operating handle.
Step 3
Install the slide arm (item 4) over the interlock lever part of the ABB
operating handle, as shown. Note that the notch in the slide arm is positioned
toward the door opening. 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 operating handle and tighten. The slide arm should move up and
down smoothly. Install interlock lever extension per ABB instructions.
Step 4
Attach the bottom of the slide arm 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 ABB operating handle.
- (B) Adjust the length of the slide arm assembly. With proper adjustment of the slide arm, the safety lock (in ABB 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 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 ABB operating handle is in the “ON” position.
Step 7
Drill and tap holes in panel per ABB instructions. Disconnect can be located
anywhere within reach of cable length being used.
See ABB instructions.
Step 8
Install panel on collar studs in enclosure.
Step 9
Mount disconnect switch or circuit breaker and operating mechanism on panel
using ABB instructions and parts.

Enclosures with Disconnect on Right Flange
INTRODUCTION
This installation instruction is for ABB Cable Controlled Small Handle
mechanisms. These mechanisms are for disconnect switches and circuit breakers
mounted in Hoffman two-door, floor−mounted enclosures with the disconnect on
the centerpost.
INSTALLATION STEPS
Step 1
Install adapter plate (item 1) and plate gasket (item 2) on the inside of the
enclosure, behind the rectangular opening provided in the centerpost. Gasket
side with PSA should be attached to the adapter plate. Secure in place with
four screws (item 3) and four nylon washers (item 14).
Step 2
Assemble the ABB 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 ABB operating handle.
Step 3
Cut 2 1/2” off bottom end of slide arm (item 4) (bottom end has rectangular
holes only).
Step 4
Install the slide arm (item 4) over the interlock lever part of the ABB
operating handle, as shown. Place the smaller diameter end of the shoulder
collar (item 5) through the oval slot in the slide arm. Note that the notch in
the slide arm is positioned toward the door opening. 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 operating handle and
tighten. The slide arm should move up and down smoothly. Install interlock
lever extension per ABB instructions.
Step 5
Attach the bottom of the slide arm 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 length of the slide arm assembly. With proper adjustment of the
slide arm, the safety lock (in ABB 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 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 ABB operating handle is in the “ON” position.
Step 8
Drill and tap holes in panel per ABB instructions. Disconnect can be located
anywhere within reach of cable length being used.
See ABB instructions.
Step 9
Install panel on collar studs in enclosure.
Step 10
Mount disconnect switch or circuit breaker and operating mechanism on panel
using ABB instructions and parts.
