Safety Summary
The following safety precautions apply to both operating and
maintenance personnel and must be observed during all phases
of operation, service, and repair of this instrument. Before applying
power, follow the installation instructions and become familiar with
the operating instructions for this instrument.
GROUND THE INSTRUMENT
To minimize shock hazard, the instrument chassis and cabinet must
be connected to an electrical ground. This instrument is grounded
through the ground conductor of the supplied, three-conductor ac
power cable. The power cable must be plugged into an approved
three-conductor electrical outlet. Do not alter the ground connection.
Without the protective ground connection, all accessible conductive
parts (including control knobs) can render an electric shock. The
power jack and mating plug of the power cable meet IEC safety
standards.
DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE

removing the instrument covers and replacing components. Under
certain conditions, even with the power cable removed, dangerous
voltages may exist. To avoid injuries, always disconnect power and
discharge circuits before touching them.

WARNINGS AND CAUTIONS
WARNING and CAUTION statements, such as the following
examples, denote a hazard and appear throughout this manual.
Follow all instructions contained in these statements.
A WARNING statement calls attention to an operating procedure,
practice, or condition, which, if not followed correctly, could result in
injury or death to personnel.
A CAUTION statement calls attention to an operating procedure,
practice, or condition, which, if not followed correctly, could result in
damage to or destruction of parts or the entire product.
WARNING
Do not alter the ground connection. Without the protective ground
connection, all accessible conductive parts (including control knobs)
can render an electric shock. The power jack and mating plug of the
power cable meet IEC safety standards.
WARNING
To avoid electrical shock hazard, disconnect power cord before

2 FEATURES
zConstant voltage / constant current power supply which
features excellent line and load regulations, low ripple and
noise characteristics.
zThe unit features separate voltage and current meters
so that output voltage and current can be monitored
simultaneously.
zOutput voltage and current can be adjusted continuously in
full range to any desired values. Adjustment can be done
easily and precisely by using separate coarse and fine
adjust knobs.
zThe constant current circuit operates to protect against
overload and output short circuit. The limiting current values
can be preset in the full range of the rated values.
zMultiple units of the 1410 can be connected in series to
provide higher output voltage.
zMultiple of the 1410 can be connected in parallel (Master/
Slave configuration) to achieve higher output current.

temperature range listed in the specification table.
zBecause the unit is cooled by natural convection, do not
place objects on top to block the convection. Also user must
avoid to place the unit on or rear any heat emitting devices
or use multiple units in stacked configuration. For best
result, use the unit in an environment that is as well cross-
ventilated as possible.

Two or more units of the 1410 can be connected in parallel to give
an increase in output current capacity. The total output current
capacity will be the sum of the output currents of the individual units.
In this mode of operation, one supply will act as the master and all
settings are from the master unit.

When connecting the supplies in
