II — INSTALLATION
KEYING. The units are keyed by voltage at the factory.
Refer to the Operator Manual for details.
MOUNTING THE POWER SUPPLY To insert in a
Kepco Rack Adapter, release the two cap head screw
retaining latches (see Figure 4) by loosening the cap-head
screw approximately 1/2 turn CCW (use 5/32" hex key)
and slide to open (up) position. Insert power supply in the
slot, then retighten the cap-head screws CW until snug.
DO NOT OVERTIGHTEN! To release, follow the same
procedure, except lift the latch to the top of the slot. Be
sure to move the latch completely up or down to ensure
full engagement/disengagement of the latching mecha-
nism. When HSP is not installed in rack adapter, secure
latch in open (up) position to prevent damage.
To use as a fixed, rack-mounted unit, see Operator man-
ual for details and accessories.
For all installations, provide adequate clearance around
air inlet and exhaust locations.
CONNECTIONS: Figure 2 shows proper connection
of one or more loads using either remote or local sensing.
If local or remote sensing is not configured, the unit
will not work properly. Observe polarities: negative
sensing wire must be connected to negative load wire,
and positive sensing wire to positive load wire. When used
with plug-in rack adapters, local sense wires must be con-
nected from the I/O connector to the ± studs of the rack
adapter.
Load connections to the HSP power supply are via bus
bars protruding from the rear panel (see Figure 2) or via
the rack adapter output studs.
Load cable or bus bar attachment should use either the
clearance hole of the HSP bus bar, using a 5/16" UNC
nut, bolt and lockwasher, or the rack adapter studs using
hardware supplied with the rack adapter. The proper hard-
ware is critical to maintaining intimate contact between the
load conductor and output bus bar.

PRELIMINARY ELECTRICAL CHECK A simple
operational check after unpacking and before equipment
installation is advisable to ascertain whether the power
supply has suffered damage resulting from shipping.
1. Power supply will not operate unless remote
sense lines are properly connected to output ter-
minals! Connect remote sense terminals to output
bus bars using mating I/O Connector (Kepco P/N 142-
0422) or other means as shown in Figure 2.
2. Connect power supply to source power. Connection
can be made using either a North American linecord
set (Kepco P/N 118-0776) or using a custom linecord
terminated at one end with an IEC 320/C19 plug
(Kepco P/N 142-0381).
3. Connect a static load, R, across output terminals.
Load value is determined by HSP nominal output volt-
age and must be capable of handling 2% of power
supply output rating (20 watts minimum). R is calcu-
lated as approximately equal to output voltage
2
/20
(R = E 2 /P). For example, for the HSP 48-21, R = 48 2 /
20 = 115.2; use load of 120 ohms, 20W.
4. CAUTION: DO NOT repeatedly toggle circuit
breaker as this may damage unit. Set Power ON/
OFF circuit breaker on front panel to ON. If actuator
