Important Safety Instructions
WARNING: High energy and high voltage
Exercise caution when using and calibrating 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: Limitations on use
The XDC is not intended for use in connection with life support systems or other medical
equipment or devices.
CAUTION
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. Contact the service technician for service and repair help. Repairs must be
made by experienced service technicians only.
CAUTION: For use as a battery charger
When you are using any of these power supplies 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 reverse polarity current protection. Where
several power supplies are in parallel, it is best to fuse each one, rather than one large fuse
for all.
