Figure 3-2: Single Power Feed/Dual Supply Terminal Connection
NOTE:
For dual incoming AC power feed systems, two (2) din rail terminal
blocks will be installed. Two separate power inputs will route thru the
conduit hole and connect to the individual terminal blocks.
Use at least 75C rated wiring for the mains supply.
In NEC Class I, Division 2 areas (only in the U.S.A.), a conduit seal ("pour
fitting") or equivalent must be installed between each electrical connection point
on the cabinet and the electrical source. Liquid tight flexible conduit can be
installed between the ChemGuard® connectors and the conduit seals to
facilitate these connections.
A maximum length of 18" (457 mm) is allowed between the last pour fitting and
the cabinet connector. All conduits shall be sealed in accordance to Sections
501-5, 502-5 or 504-70 of the National Electric Code.
NOTE:
For Systems approved for installation and use in Explosive
Atmospheres (Europe), refer to section 4.7 for additional instructions.
