INTRODUCTION

This installation instruction is for the Allen−Bradley Small Handle.

Bulletin 1494V (variable depth), 1494C and 140U (cable control) mechanisms.

These mechanisms are for disconnect switches and circuit breakers mounted in Hoffman two-door, oor−mounted enclosures

with cutout on right-hand ange or centerpost and one- through ve-door, free−stand enclosures with the disconnect on the right

ange.

ALLEN-BRADLEY SMALL HANDLE INSTALLATION STEPS

See Figure 1 for 1494V or Figure 2 for 1494C and 140U Mounting.

Step 1: Install Allen-Bradley Small Operating Handle 1494F-S1 (Stainless Steel), 1494F-P1 (Non-metallic) or 1494F-M1 (Metal).

(1494V) Assemble the Allen−Bradley small operating handle and Allen−Bradley spring bracket to the enclosure ange. Omit cap

screw and lockwasher which t into bottom hole of Allen−Bradley operating handle.

(140U) Assemble the Allen−Bradley small operating handle and Allen−Bradley 140U H, J, K, M, OR N operating mechanism to

enclosure ange. Omit cap screw and lockwasher which t into bottom hole of Allen−Bradley operating handle.

(1494C) Assemble the Allen−Bradley small operating handle and Allen−Bradley 1494C CM and CMX operating mechanism to

enclosure ange. Omit cap screw and lockwasher which t into bottom hole of Allen−Bradley operating handle.

Step 2: Install Slide Arm.

Note: When mounting to centerpost, cut 2.50 inches off bottom of slide arm (item 1). Bottom of slide arm has three rectangular

slots.

(A) For 1494V install the slide arm (item 1) through the hole in bottom of Allen−Bradley spring bracket and over the defeater part

of the Allen−Bradley operating handle as shown.

(A) For the 1494C and 140U install the slide arm (item 1) over the defeater part of the Allen−Bradley operating handle as shown.

(B) Note that the notch in the slide arm (item 1) is positioned toward the door opening. Place the smaller diameter end of the

shoulder collar (item 2) through the oval slot in the slide arm (item 1). Install long cap screw (item 3) with lockwasher (item 4)

through shoulder collar into the bottom mounting hole of the Allen−Bradley operating handle and tighten. The slide arm (item 1)

should move up and down smoothly. Install Allen−Bradley defeater bracket per Allen−Bradley instructions.

Step 3: Attach the bottom of the slide arm (item 1) to the offset arm of the operator release mechanism. Use two at washers

(item 5), two lockwashers (item 6), and two hex nuts (item 7). Do not tighten until parts are adjusted (see Step 4B).

Step 4: The operator 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 portion of the roller

bracket when the door is closed and latched. Adjust up or down if necessary. The mechanism will then provide the necessary up−

down motion required to operate the safety lock release in the Allen−Bradley operating handle.

(B) Adjust the length of the slide arm assembly with proper adjustment of the slide arm. The safety lock (in the Allen−Bradley

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. Tighten all hardware.

Step 5: Attach the door catch (item 8) provided by Hoffman to the tapped spacer on the door using the bottom set of mounting

holes. Use two screws (item 9) and two lockwashers (item 10). The door catch prevents the door from being opened when the

Allen−Bradley operating handle is in the “ON” position. The door catch may be adjusted up or down to hook properly on the

defeater bracket. The door catch (item 8) must be positioned so it just clears the top of the defeater bracket when the Allen−

Bradley operating handle is in extreme “OFF” position (handle pushed down against the handle housing surface).
