The pins of the prime power connector should be wired as follows:
Pin A—Line or (Phase A)
Pin B—neutral/line or (Phase B)
Pin C—Protective Earth (PE)
WARNING! AC PRIME POWER MUST BE REMOVED VIA AN EXTERNAL
CIRCUIT BREAKER BEFORE DISCONNECTING OR CONNECTING THE
PRIME POWER CONNECTOR ON THE CHPA. DO NOT APPLY POWER TO
THE CHPA UNTIL COMPLETION OF THE INSTALLATION.
WARNING! CONSTRUCT THE AC PRIME POWER CABLE ASSEMBLY IN
ACCORDANCE WITH LOCAL AND/OR NATIONAL ELECTRICAL CODES.
CPI RECOMMENDS THAT A LICENCED ELECTRICIAN FABRICATE THE
PRIME POWER CABLE ASSEMBLY FOR USE AT THE INSTALLATION SITE.
2.5.4 Grounding
Note: Proper grounding of the CHPA amplifier to the station ground buss
or to earth ground is necessary for personnel and equipment safety. The
ground screw on the CHPA rear panel must be used for this purpose.
2.5.5 I/O
Interfaces
I/O interface connections are made at the rear panel of the CHPA via J4-J8, which are all
standard D-shell connectors. All of the D-shell connectors (except J8) on the rear panel of the
CHPA are female or “socket,” meaning that interface cables constructed by the user must utilize
male or “pin” gender D-shell connectors. Shielded cables should be used with these interfaces.
For best EMI performance, use metal shell connectors and connect the cable shield directly to
the connector shell. (Refer to Chapter 3, “Interfaces,” for pin-out information.)
