2.6.3.3
D-C SOURCE POWER
For d-c source power, wire the rack adapter in accordance with the instructions for single-phase
a-c power per Para. 2.6.3.1. Contact Kepco Applications Engineering for additional restrictions
imposed by d-c source power.
2.6.4
CONTROL SIGNAL CONNECTIONS
Access to the control signal (I/O) connector for each HSP power supply is provided via the three
37-pin D-subminiature connectors on the rear panel of the rack adapter (see Figure 2-2). Three
mating connectors (Kepco PN 142-0422) are provided in a plastic bag. These connectors are
simply extensions of the identical connectors located on the HSP power supplies. Consult the
HSP operator's manual for instructions on wiring and use of these control lines.
2.6.4.1
SENSE CONNECTIONS
The user MUST configure either local or remote sensing. Local sensing is accomplished by con-
nS (pin 37) of the I/O Connector to the + stud at the rear of the rack adapter, and –S (pin
19) of the I/O Connector to the – stud. Remote sensing is accomplished by connS (pin
37) of the I/O Connector to the + terminal of the load, and –S (pin 19) of the I/O Connector to the
– terminal of the load. Refer to HSP Operator manual for instructions on wiring.
NOTE!
REGARDLESS OF OUTPUT CONFIGURATION, OUTPUT SENSE
LINES MUST BE PROPERLY CONNECTED FOR OPERATION
(REFER TO HSP OPERATOR'S MANUAL).
2.6.5
OUTPUT LOAD CONNECTIONS
Load connections to the rack adapters are achieved via the stud pairs located on the rear panel
directly behind each mounting position (see Figure 2-2). Required hardware for attaching output
cables are assembled to the output studs. Wires must be sized according to expected current.
Wire size range is between 22 and 6 GA, depending on the ring lug; torque to 40 lb-in (45 N•M)
maximum. RA 60 rack adapters provide permanent interconnection of the three power supply
positions for parallel/redundant configuration. All three load connections must be used when the
3.3 volt and 5 volt modules are used. RA 62 and RA 63 rack adapters employ a modular bus bar
system to permit a variety of load configurations. The following sections describe the basic out-
put bus bar configurations available with Series RA 60 rack adapters. Additional information
regarding these and other load interface requirements are contained in the HSP operator's man-
ual.
