(1)
When installing unit in topmost location in vertical sections, care must be taken to comply with the 2005 National Electrical Code (reference code: Article 404.8 and UL 845)
6’7” (2000 mm) unit handle-to-floor height limitation. A unit operating handle extender (2100-NE1) is available which provides 3” (76.2 mm) added height flexibility.
(2)
When Bulletin 2100, 0.5 space factor units are ordered unassembled or ordered for existing sections, a centralized wiring diagram holder kit (2100H-WDH) should be
ordered.
(3)
Permits installation of 0.5 space factor plug-in units in existing series E through J Bulletin 2100 vertical sections.
(4)
Replacement and renewal parts are no longer supported. Consult MCC Technical Support at 1-800-646-5800
(5)
Required only if series F or later, 1.0 space factor or larger Bulletin 2100 unit is installed in topmost location of series A through E vertical sections.
(6)
Consult MCC Technical Support at 1-800-646-5800 for assistance with possible door hinge requirements.
(7)
Series E-J sections cannot accommodate 0.5 space factor units in bottom-most unit location.
(8)
A ground strap can be used to ground units rather then installing a ground bus. See publication 2100-IN014x-EN-P.
