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. Two door enclosure with disconnect on right flange One through six door enclosure with disconnect on right flange Master Door Master Door INSTALLATION STEPS Step 1 Install adapter plate (item 1 or 15) 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 I T E 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 I T E operating handle. Step 3 Install the slide arm (item 4 or 16) 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 or 17) through the oval slot in the slide arm. Install long cap screw (item 6 or 18) with lockwasher (item 7 or 19) 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 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 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 lockwashers (item 13). The door catch prevents the door from being opened when the I T E operating handle is in the ON position. The door catch may be adjusted up or down to hook properly on the interlock blade. The door catch (item 11) must be positioned so it just clears the top of the interlock lever extension when the I T E operating handle is in extreme OFF position. Step 7 Drill and tap holes in panel as shown in diagram and table. 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. 87569274 2005 Hoffman Enclosures Inc. 3

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 centerpost. Master Door INSTALLATION STEPS Step 1 Install adapter plate (item 1 or 15) and plate gasket (item 2) on the inside of the enclosure, behind the rectangular opening provided in the centerpost. Secure in place with four screws (item 3). 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 lockwasher which fits into bottom hole of I T E operating handle. Step 3 Cut 2 1/2 off bottom end of slide arm (item 4 or 16). (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 or 17) through the oval slot in the slide arm. Install long cap screw (item 6 or 18) with lockwasher (item 7 or 19) 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 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 I T E operating handle) should release just before the master door is fully latched. Lengthen slide arm if safety lock releases too soon.
