Important Safety Instructions
Power Supply Safety Markings
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. F i l t e r
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 “Return Material Authorization
Policy” on page WA – 3.
WARNING: Limitations on use
The XG 850 Watt Series 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.

Safety
viii M370078-01
Standard Warnings
1. Before installing and using the XG 850 Watt Series Programmable
DC Power Supply, read all instructions and cautionary markings on
the XG and all appropriate sections of this Manual.
2. The XG is for indoor use only. Do not expose the XG to moisture. To
reduce risk of fire hazard, do not cover or obstruct the ventilation
openings. Be sure to install the XG in a compartment which allows air
to reach the ventilation inlets on the front and rear of the unit to
prevent overheating. For more information, see “Ventilation” on
page 2–4.
3. To avoid a risk of fire and electric shock, make sure that the existing
wiring is in good condition and the wire is not undersized. Do not
operate the XG with damaged or substandard wiring.
4. Do not operate the XG if it has received a sharp blow, been dropped,
or otherwise damaged in any way. If the XG is damaged, see
“Warranty and Product Information” on page WA – 1 .
5. Do not disassemble the XG. It contains no user-serviceable parts. See
the “Warranty and Product Information” on page WA –1 for
instructions on obtaining service. Attempting to service the XG
yourself may result in a risk of electrical shock or fire. Internal
capacitors remain charged after all power is disconnected.
6. To reduce the risk of electrical shock, disconnect AC power from the
XG before attempting any maintenance or cleaning or working on
any circuits connected to the XG. Turning off controls will not reduce
this risk.
WARNING: Keep these instructions
This chapter contains important safety and operating instructions. Read and keep
this Operating Manual for future reference.
