III — INSTALLATION
3.1. UNPACKING. The power supply has been thor-
oughly inspected and tested prior to packing and is ready
for operation. After careful unpacking, inspect for shipping
damage before attempting to operate. Perform the Prelim-
inary Checkout (PAR. 3.2). If any indication of damage is
found, file an immediate claim with the responsible trans-
port service
3.2. PRELIMINARY CHECKOUT. A simple operat-
ing check after unpacking and before permanent installa-
tion, is advisable to ascertain whether the BOP has
suffered damage in shipment.
1. Install PC15 (supplied) at rear panel. This is required
for local control of the unit.
2. Refer to Safety instructions (see Section IV) and con-
nect unit to 115V a-c source; see Operator manual
(PAR 1.1) for different source voltage.
3. Set the BOP front panel controls as follows
a. Voltage/Current MODE select switch set to VOLT-
AGE.
b. Voltage Control ON/OFF switch to ON, Voltage
Control to extreme counterclockwise position.
c. A-C POWER circuit breaker/switch to ON.
d. The E
O
Mode indicator will be “on.”
4. Turn the Voltage Control clockwise through its range,
while observing the front panel Voltmeter. The BOP
output voltage should respond smoothly, from the max-
imum negative output voltage, through zero, to the
maximum positive output voltage of the BOP.
5. Set A-C POWER circuit breaker/switch OFF.
6. Connect a short circuit between the OUTPUT and
COMMON front panel output terminals.
7. Set the BOP front panel controls as follows:
a. Voltage/Current MODE select switch set to CUR-
RENT.
b. Current Control ON/OFF switch to ON and Current
Control to its maximum counterclockwise position.
c. A-C POWER circuit breaker/switch to ON.
d. The I
O
Mode indicator will be “on.”
8. Turn the Current Control clockwise through its range,
while observing the front panel Ammeter. The BOP
output current should respond smoothly, from the max-
imum negative output current, through zero, to the
maximum positive output current of the BOP.
9. Set A-C POWER circuit breaker/switch OFF. Remove
the short circuit from the output terminals. This con-
cludes the preliminary check-out of the BOP.
3.3. INSTALLING THE POWER SUPPLY.
3/4 RACK MODELS. These models are shipped with four
plastic feet installed for benchtop operation. The feet must
be removed for rack mounting. Kepco’s RA 24 or RA 37
can be used to install these models in a standard 19-inch
rack (installation instructions supplied with rack adapter).
Four plastic mounting inserts on the bottom of the chassis
can be used to mount the unit on any flat surface.
FULL RACK MODELS. These models are shipped with
fixed angle brackets and chassis slide support bars
installed and are ready for mounting in a 19-inch rack.
3.4. CONNECTIONS. Connections can be made
using either the front or rear panel terminations, but not
both.
LOAD CONNECTIONS. Connect the load between OUT-
PUT and COMMON terminals. Connections may be made
at either the front or rear panel. Sense connections are
required, either local or remote, must be used; other-
wise the unit will not operate.
SENSE CONNECTIONS. For local sensing The OUTPUT
and COMMON terminals are connected to the adjacent
SENSE terminals. The unit is shipped with local sensing
links in place at the rear panel. If load connections are
made at the front panel, remove the installed links from
the rear panel. At the front panel install jumpers between
COMMON and the adjacent SENSE terminal and
between OUTPUT and the adjacent SENSE terminal. If
desired, a link between terminals 5 and 6 at the rear panel
may be installed to enable the Grounding Network.
Remote sensing (connecting the corresponding SENSE
terminals to the OUTPUT and COMMON terminations at
the load instead of at the BOP) can compensate for load
wire losses up to 0.5V per wire. Remote sensing is recom-
mended for minimum load effect for a remote load. Use
twisted pairs: #22 AWG for output sense lines and wires
rated for the nominal output current of the power supply
for power leads. See full Operator Manual (see PAR. 1.1)
for remote sensing requirements.
