Important Safety Instructions
WARNING: High energy and high voltage
Exercise caution when using a power supply. High energy levels can be stored
at the output voltage terminals on a power supply in normal operation. In
addition, potentially lethal voltages exist in the power circuit and on the output
and sense connectors of a power supply with a rated output greater than 40 V.
Filter capacitors store potentially dangerous energy for some time after power is
removed.
WARNING: Fire hazard
Operate the power supply in an environment free of flammable gases or fumes.
To ensure that the power supply's safety features are not compromised, use the
power supply as specified in this Manual and do not substitute parts or make any
unauthorized modifications. If service is necessary, please return the power
supply to the Authorized Service Center. See the Warranty on page ii.
WARNING: Limitations on use
The XG Family Programmable DC Power Supply is not intended for use in
connection with life support systems or other medical equipment or devices.
CAUTION: For use as a battery charger
When you are using a power supply for battery charging applications, it is
essential to provide an appropriately sized fuse or circuit breaker in series
between the power supply output and the battery.
Installation of a protector (fuse or DC circuit breaker), rated for about 115% of
the maximum current rating of the power supply and designed specifically to
interrupt the DC voltage of the battery, will provide adequate current protection.
Where several power supplies are in parallel, it is best to fuse each power supply
rather than use one fuse at the battery.
