Outline Diagram
Figure 1 illustrates the outline shape and dimensions of the
supply.
Rack Mounting
This supply may be rack mounted in a standard 19-inch rack
panel either by itself or alongside a similar unit. Please see
the ACCESSORY, page 1-4, for available rack mounting
accessory. The rack-mounting kit includes complete installa-
tion instructions.
INPUT POWER REQUIREMENTS
Depending on the line voltage option ordered, the supply is
ready to be operated from one of the power sources listed in
Table 1. A label on the rear heat sink shows the nominal input
voltage set for the supply at the factory.
Power Cable
To protect operating personnel, the supply should be
grounded. This supply is equipped with a three conductor
power cable. The third conductor is the ground conductor and
when the cable is plugged into an appropriate receptacle, the
supply is grounded. The power supply is equipped at the fac-
tory with a power cord plug appropriate for the user's location.
Notify the nearest HP Sales and Service Office if the appro-
priate power cord is not included with the supply.

OPERATING INSTRUCTIONS
INTRODUCTION
This section describes the operating controls and indicators,
turn-on checkout procedures, and other operating consider-
ations for the Model E3620A Dual Output Power Supply.
Before applying power to the supply, check the label on the
heat sink to make certain that the supply's line voltage option
agrees with the line voltage to be used. If the option does not
correspond to your line voltage, refer to paragraph "LINE
VOLTAGE OPTION CONVERSION" in the service section
before applying power.

CONTROLS
Line Switch
The LINE pushbutton switch (
, Figure 2) is pushed-in to
turn the supply ON and released (out position) to turn the
supply OFF.
Voltage and Current Metering
Two meter select pushbutton switches (
and
) permit the
output voltage and current of either output (V1 or V2) to be
monitored on the VOLTS/AMPS meter. The V1 and V2 output
select pushbuttons connect the desired output to the meter-
ing circuit when the applicable button is pushed in.
Be careful that both METER pushbuttons are not released
(out-position) or pushed in simultaneously.
Voltage Controls
The V1 and V2 voltage controls (
and
) set the voltage
level of the corresponding output. The voltage controls are 10
turn potentiometers.
