2.1 UNPACKING AND INSPECTION
This equipment has been thoroughly inspected and tested prior to packing and is ready for
operation. After careful unpacking, inspect for shipping damage before attempting to operate. If
any indication of damage is found, file an immediate claim with the responsible transport ser-
vice. See Table 2-1 for a list of equipment supplied.
2.2 RACK ADAPTER KEYING INSTRUCTIONS
The RA 59 rack adapter incorporates a keying mechanism to prevent accidental insertion of the
incorrect model HSP power supply into any position. The HSP power supplies are keyed by
voltage at the factory. The keying mechanism will prevent engagement of any of the HSP power
supply’s connectors with those on the rack adapter’s intermediate plate unless the key and key-
way align. The user can configure each power supply position of the rack adapter for the desired
voltage in the desired position; the factory default keying is for the 5 volt HSP module (see Fig-
ure 2-1).
2.2.1 ESTABLISHING KEY POSITIONS
The key pins (Kepco PIN 108-0079) used for module keying are located on the intermediate
plate (see Figure 2-1) and are accessed through the front of the rack adapter. To alter the keying
of any position, simply unscrew the key pin from the intermediate plate using a 1/4” nut driver or
deep socket, reposition key pin at new location and retighten. HSP module keying is identified in
Figure 2-1 and in the HSP operator’s manual. DO NOT ALTER THE KEYING AT THE POWER
SUPPLY!
