INTRODUCTION
This installation instruction is for I−T−E MAX−FLEX™ 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 (item14).
Step 2
Assemble the I−T−E operating handle to the mounting plate which was installed
in the enclosure in step 1. Omit cap screw and lock washer which fits into
bottom hole of I−T−E operating handle.
Step 3
Install the slide arm (item 4) over the interlock lever part of the I−T−E
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 lock washer (item 7)
through shoulder collar into the bottom mounting hole of the I−T−E operating
handle and tighten. The slide arm should move up and down smoothly. Install
interlock lever extension per I−T−E 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 lock washers (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 I−T−E operating handle.
(B) Adjust the length of the slide arm assembly. With proper adjustment of the
slide arm, the safety lock (in I−T−E 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
lock washers (item 13). The door catch prevents the door from being opened
when the I−T−E operating handle is in the “ON” position.
Step 7
Drill and tap holes in panel per I-T-E instructions. Disconnect can be located
anywhere within reach of cable length being used. See I−T−E instructions.
Step 8
Install panel on collar studs in enclosure.
Step 9
Mount disconnect switch or circuit breaker and operating mechanism on panel
using I−T−E instructions and parts.

INTRODUCTION
This installation instruction is for I−T−E MAX−FLEX™ mechanisms. These
mechanisms are for disconnect switches and circuit breakers mounted in Hoffman
two door, floor−mounted enclosures with the disconnect on the center post.
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 center post. 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
Assemble the I−T−E operating handle to the mounting plate which was installed
in the enclosure in step 1. Omit cap screw and lock washer which fits into
bottom hole of I−T−E operating handle.
Step 3
Cut 2 1/2 inches 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 I−T−E
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
lock washer (item 7) through shoulder collar into the bottom mounting hole of
the I−T−E operating handle and
tighten. The slide arm should move up and down smoothly. Install interlock
lever extension per I−T−E 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 lock washers (item 9), and two
hex nuts (item 10). Do not tighten until parts are adjusted.
