This module mounts in a 1756 chassis and uses a separately-ordered
RTB or a Bulletin 1492 Interface Module (IFM)
(1)
to connect all
field-side wiring. This module uses one of the following RTBs:
•
1756-TBNH 20 position NEMA RTB
•

Use an extended-depth cover (1756-TBE) for applications with heavy
gauge wiring or requiring additional routing space. When using an
IFM, consult the documentation that came with it to connect wiring.

The Bulletin 1492 IFM may not be used in any application that requires agency certification of the

system. Use of the IFM violates the UL, CSA and FM certifications of this product.
