II — SAFETY.
Exercise care in making all connections to and from the
BOP terminals.
WARNINGS
1. Remove a-c power from the BOP before making any
connections.
2. Wires and/or cables, connected from the BOP termi-
nals to external components or programming devices
must be properly insulated and securely terminated on
both sides to make accidental touch impossible. DO
NOT USE BANANA PLUGS WITH EXPOSED
SCREWS OR OTHER EXPOSED METAL PARTS AT
THE FRONT PANEL OUTPUT TERMINALS!
3. The BOP chassis and cover must be safety-grounded
to a reliable a-c source ground. A safety-ground may
be established by using a grounded a-c power outlet
or, if the latter is not available, by means of a separate
wire, from the provided GROUND terminal to a reliable
a-c source ground point.
4. THE COMMON OUTPUT TERMINAL OF THE BOP
MAY EITHER FLOAT OR BE GROUNDED. Leave the
output terminal floating when an external, grounded
programming device is used. For noise/ripple reduc-
tion ground a single return terminal on either the pro-
gramming device, the BOP or the load configuration.
See PAR 3.4 for the maximum allowable floating volt-
age for the COMMON output terminal.
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 oper-
ating check after unpacking and before permanent instal-
lation, 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. For BOP 5-20DL only: apply voltage (+3.5 to +24V) to
pin 2 referenced to pin 3 of ON-OFF PORT at rear
panel (enables the output).
3. Refer to Safety instructions (see Section II) and con-
nect unit to 115V a-c source; see Operator Manual
(PAR 1.1) for different source voltage.
4. 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. For BOP 5-20DL
the REMOTE OUTPUT ON-OFF indicator will also
be on.
5. 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.
6. For BOP 5-20DL only: disconnect voltage applied to
rear panel ON-OFF PORT. Verify that front panel
VOLTAGE and CURRENT meters show 0V and 0A,
respectively, and REMOTE OUTPUT ON-OFF indica-
tor goes off.
7. Set A-C POWER circuit breaker/switch OFF.
8. Connect a short circuit between the OUTPUT and
COMMON front panel output terminals.
9. 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. For BOP 5-20DL only: apply voltage (+3.5 to +24V)
to pin 2 referenced to pin 3 of ON-OFF PORT at
rear panel (enables the output).
d. A-C POWER circuit breaker/switch to ON.
e. The I
O
Mode indicator will be “on.”
