MOUNTING EAR INSTALLATION
If mounting ears are removed, or optional mounting ears are purchased to allow installation in a
different size rack (see Table 1-2), install each standard (flush) mounting ear on the rack adapter
cover as shown in Figure 2-5). Attach mounting ear to cover using the four screws provided.
Installation of the setback mounting ears is similar to the above procedure, except the setback
flange is first inserted in the slot on the rack adapter cover, then rotated 90 degrees as shown in
Figure 2-5).

WIRING INSTRUCTIONS
Interconnections between an a-c power source and a stabilized power supply, and between the
power supply and its load are as critical as the interface between other types of electronic equip-
ment. If optimum performance is expected, certain rules for the interconnection of source,
power supply and load must be observed by the user. These rules are described in detail in the
following paragraphs and in the operating instructions for HSP Series power supplies.
2.6.1
SAFETY GROUNDING
Local, national and international safety rules dictate the grounding of the metal cover and case
of any instrument connected to the a-c power source, when such grounding is an intrinsic part of
the safety aspect of the instrument. The instructions below suggest wiring methods which com-
ply with these safety requirements; however, in the event that the specific installation for the
power system involves differences with the recommended wiring, it is the customer's responsi-
bility to ensure that all applicable electric codes for safety grounding requirements are met.
2.6.2
SOURCE POWER CONNECTIONS
When used in conjunction with Kepco HSP series power supplies, these rack adapters can be
operated from either single-phase or three-phase a-c source power without adjustment or modi-
fication. Voltage and frequency limits are determined by the source power rating of the HSP
power supplies. Operation from d-c power is also available; please contact factory for limitations
imposed when using d-c source power.
