II — SAFETY.
Exercise care in making all connections to and from the
ATE terminals.
WARNINGS
1. Remove a-c power from the ATE before making any
connections.
2. Wires and/or cables, connected from the ATE terminals
to external components or programming devices must
be properly insulated and securely terminated on both
sides to make accidental touch impossible.
3. The ATE 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 (at the rear barrier
strip) to a reliable a-c source ground point.
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 Prelimi-
nary 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 ATE has suffered
damage in shipment.
1. Install Programming Connector (supplied) at rear panel.
This is required for local control of the unit.
2. Refer to Safety instructions (see Section II) and connect
unit to 115V a-c source; refer to Operator manual (see
PAR 1.1) for different source voltage.
3. Set the ATE front panel controls (Figure 1) as follows:
a. Turn CURRENT control fully clockwise.
b. Turn VOLTAGE control fully counterclockwise.
c. Set a-c power ON/OFF switch/circuit breaker to ON.
d. Verify that Voltage MODE indicator is on.
4. Slowly turn VOLTAGE control clockwise and observe a
gradual increase of output voltage. Verify that the
VOLTMETER reads full scale when control is fully
clockwise.
5. Check the overvoltage “crowbar” circuit as follows:
a. Turn the VOLTAGE control to about one-half of its
range.
b. Depress the DISARM pushbutton and turn the
(recessed) LEVEL control slowly counterclockwise
until the CROWBAR indicator lights.
c. Turn VOLTAGE control slightly counterclockwise
and release DISARM button. Now when the VOLT-
AGE control is increased to the overvoltage set-
point, the input circuit breaker trips off.
d. To set overvoltage to a different value repeating
steps a, b, and c, except at step a set the VOLTAGE
control to the desired overvoltage setting.
e. Turn A-C POWER switch/circuit breaker to OFF.
6. Place a short circuit across the ATE output terminals.
Turn CURRENT control counterclockwise. Turn the ATE
power to ON. THE CURRENT MODE indicator should
now be on. Slowly turn CURRENT control clockwise
and observe the gradual increase in output current. Ver-
ify that the AMMETER reads full scale when the control
is fully clockwise.
7. 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 ATE.
3.3. INSTALLING THE POWER SUPPLY.
ATE models are shipped with four plastic feet installed for
benchtop operation. The feet must be removed for rack
mounting. Kepco’s RA 24, RA 32 or RA 37 Rack Adapters
can be used to install these models in a standard 19-inch
rack (installation instructions supplied with rack adapter).
