7. Set position 10 to ON. This connects the common lines
(-COM) for slots 4 and 3.
Configure DIP 3:
1. (HSF 300W, 600W only) Set positions 1 and 2, to ON.
This connects +S to +V and –S to –V for slot 3, estab-
lishing local sensing for slot 3.
(HSF 1200W/1500W only) Always set positions 1 and 2,
to OFF. Local/remote sensing not used.
2. (HSF 300W, 600W only) Set positions 3 and 4, to OFF.
This isolates sense lines (±S) between slots 3 and 2.
(HSF 1200W/1500W only) Always set positions 3 and 4,
to OFF. Local/remote sensing not used.
3. Set position 5 to OFF. This isolates the current share
bus (CB) between slots 3 and 2.
4. Set position 6 and 7, to OFF. This isolates the ALARM
(N.O.) and ALARM (COM) lines between slots 3 and 2.
5. Set position 8 to OFF. This position is only set to ON for
open-on-fail alarm circuits.
6. Set position 9 to OFF. Isolates RV (remote voltage) lines
between slot 3 and 2, however RV is not used (output
voltage is controlled by the front panel trimpot).
7. Set position 10 to OFF. This isolates common (-COM)
lines between slots 3 and 2.
SERIES OPERATION. See Operator Manual for
series operation details.
ALARMS. For independent configurations, Close on
Fail contact closure is across I/O connector pins 7 (ALARM
N.O.) and 14 (ALARM COM). Open on Fail circuits are
across I/O connector pins 6 (ALARM N.C.) and 14 (ALARM
COM). Figure 3 shows a parallel close-on-fail circuit for
slots 3 and 4 using the DIP switches to make the connec-
tions. See Operator Manual for other options.
III — INSTALLATION
MOUNTING RACK ADAPTER: The rack adapter
mounts directly to EIA-RS 310D standard 19" racks via the
two mounting ears; two screws are required per mounting
ear for proper support. CAUTION: RACK ADAPTER
SHOULD BE MOUNTED BEFORE INSTALLING POWER
SUPPLIES. Install each HSF power supply in desired slot
and secure using two retaining latches as described by the
applicable HSF Power supply manual. Make sure the two
latches are in the open position before installing HSF mod-
ules.
The rack adapter is supplied with six cable clamps
equipped with release levers that can be snapped into
holes provided in the rear panel (see Figure 1) to support
the weight of the input, output and signal cables.
OPTIONAL PROTECTIVE COVER: A clear plastic
cover (Kepco P/N 137-0145) is available as an accessory
to protect the rear terminals against accidental contact.
See Operator Manual for details.
OPTIONAL BUS BAR: Bus bars which connect output
terminals for parallel or series operation are available as
accessories. See Operator Manual for details.
OPTIONAL KEYING: HSF power supplies are keyed
by voltage at the factory. The keyway is established by
installing screws (4-40 x 0.75 in. thread-forming, Kepco P/
N 101-0480, provided) into the corresponding holes as
indicated in Figure 2 so that the only holes open match the
power supply pins. DO NOT OVERTIGHTEN these screws
(max torque 5 in.-lbs. (0.6 N x m).

OPTIONAL I/O CONNECTOR: Mating Europlugs
(Kepco P/N 142-0544) for the Alarm I/O Euroheaders are
available as accessories for the Sense connections (±S)
and independent Alarm connections.
OPTIONAL A-C CONNECTIONS: Two line cords are
available as accessories. In North America where 115/
230V a-c source power is used, Kepco recommends the
use of a Kepco line cord (P/N 118-1145, North American
style plug, 30A maximum, 6 ft. long). European applica-
tions may require the use of Kepco line cord P/N 118-1146
(250V, 32A maximum).
INSTALLATION/REMOVAL OF HSF POWER SUP-
PLIES: Use two retaining latches on each HSF power
supply to install or remove power supply to/from desired
slot in accordance with the applicable HSF Power supply
manual. Refer to RA 19-4C Operator Manual for keeping
the power supplies secure under severe shock or vibration
conditions.
