    2.4). RACK ADAPTER KEYING INSTRUCTIONS RA 19-4C rack adapters incorporate a keying mechanism to prevent accidental insertion of the incorrect model HSF power supply into any position. The HSF power supplies are keyed by volt- age at the factory. The keying mechanism will prevent engagement of any of the HSF power supply's connectors with those on the rack adapter's back plate unless the key and keyway align.

  • Page 20: Establishing Key Positions

    To establish the keying of any position, simply install the 4-40 x 0.75 in. thread-forming screws (Kepco P/N 101-0480) into the corresponding holes as indicated in Figure 2-1. DO NOT OVER- TIGHTEN these screws (max torque 5 in.-lbs. (0.6 N x m). DO NOT ALTER THE KEYING AT THE POWER SUPPLY.

    The impedance of the load wires between each power supply and load should be the same. In addition, multiple RA 19-4C rack adapters that are fully populated with identical HSF power supplies may be paralleled using external wiring at the I/O connectors.
  • Page 27 NOTE: When connections are made at the I/O mating connector, use shielded wire for con- nections to RV pins. Match impedance of load wires between each power supply and load by using the same wire lengths and wire sizes. RA 19-4C 120318...

    For group control requiring a redundant system Kepco recommends configuring all parallel con- nected units as slaves (see Table 2-3) controlled by a remote voltage. To eliminate a single point failure possibility the remote voltage should have a backup and be connected in parallel to more than one I/O connector.

    2.4.3 SERIES CONNECTION HSF power supplies may be connected in series to obtain higher output voltages. The RA 19-4C rack adapter is designed to safely handle a maximum output voltage of 500 Volts; contact Kepco Applications Engineering for additional information. The power supply with the lowest rated value of maximum current establishes the maximum load current allowed.

  • Page 50: Installing Optional Locking Bracket

    Use of this bracket will increase the time required to remove and replace a module, and there is a possibility the rack adapter may be scratched during the process; contact Kepco applications engineering to be sure this bracket is the right solution.

  • Page 51: Installing Hsf Power Supplies

    NOTE: If optional locking bracket is in use, refer to PAR. 2.8.3 for power supply installation. Refer to Figure 1-1, for proper slot positions applicable to the RA 19-4C Rack Adapter. With the retaining latches disengaged (at the top of the slot) as described above, insert HSF power sup- ply in selected slot until power supply front panel is flush with rack adapter chassis, then secure the retaining latches as described above.

    2.11.2 SOURCE POWER CONNECTIONS The RA 19-4C rack adapter is designed to be used in conjunction with Kepco HSF series power supplies. Source power requirements are determined by the HSF power supply (see HSF power supply Instruction Manual); no adjustment or modification of the rack adapter is required.

    FCC Class B. It may be necessary to add external source power filtering, such as installing snap-on ferrite beads on the line cord wires of the RA 19-4C as close to the input a-c terminal block as possible. Another option is to add an in-line cabinet-mounted EMI filter (available from a number of manufacturers) between the source power and the RA 19-4C line cord.

    2.11.4.4 MIXED OPERATION The design of the RA 19-4C rack adapters permits the user to configure HSF power supplies for almost any combination of independent, series and parallel operation, both within a single rack adapter and between different RA 19-4C rack adapters, within the limits of the HSF operation envelope and the current and voltage ratings specified in PAR.s 2.11.4.2 and 2.11.4.3.
