SECTION 2 - INSTALLATION
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
CONFIGURING THE RACK ADAPTER
Prior to installation the rack adapter must be configured by the user. Configuration consists of
the following:
• For configurations that use multiple output voltages it is possible to key the rack adapter
to accept only a power supply with corresponding keying (see PAR 2.3).
• Configuring slots for independent, parallel, or series operation. This can be done by
means of DIP switches mounted on the rear panel, or externally by wiring the associated
I/O mating connector or mating Euro plug and (+) and (–) OUTPUT terminals (see PAR.
2.4).
2.3
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. The key pins are on the HSF power supply and are set at the factory. DO NOT ALTER
THE KEYING AT THE POWER SUPPLY. The keyway is established by installing screws (pro-
vided) so that the only open holes match the power supply pins; maximum torque is 5 in.-lbs.
The user can configure each power supply slot for the desired voltage in the desired position.
Figure 1-4 shows the location of key positions for each slot and Figure 2-1 shows the configura-
tion required for voltage selection.
