Compliance with Electromagnetic Compatibility Standards H-3
H.4.4 Rail Ports
The two rail Rail Ports must not be used for CE applications. As an alternative, digital
I/O can be configured using either the digital I/O on the Resolver and Drive I/O Module
or the Allen-Bradley Remote I/O Interface Module (M/N 57C443) and Allen-Bradley
I/O.
H.4.5 Resolver and Analog Input Wiring
Resolver cable M/N 417900-207CG is recommended. This specific cable was chosen
per instruction manual D2-3115-2, (Installing, Operating, and Maintaining Engineered
Drive Systems), as the only cable not required to be installed in conduit. Conduit is not
required for CE purposes, but it may be required for a specific application.
Use shielded 2-conductor cable for analog input wiring. The shield drain wire is to be
grounded to the cable terminal board and left open at the opposite end.
H.4.6 Digital I/O Wiring
The 115 VAC source voltage for the digital I/O must be supplied from the secondary of
the isolation transformer. When a main contactor is used, an RC suppressor
(M/N 600686-33A or equivalent) must be installed across the coil contacts.
