• Wye Power - Connect a separate wire pair from each Lx/Nx pair on the rack adapter to line
and neutral terminals of the power source, using successive line terminals (e.g., A-N, B-N,
C-N) (see Figure 2-8)
FIGURE 2-8. THREE PHASE WYE A-C SOURCE POWER WIRING
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-
necting +S (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 connecting +S (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).
