1.  Before installing and using the XG and XTR Family Programmable 
DC Power Supply, read all instructions and cautionary markings on 
the instrument and all appropriate sections of this Manual. 
2.  This instrument is for indoor use only. Do not expose the instrument 
to moisture. To reduce risk of fire hazard, do not cover or obstruct 
the ventilation openings. Be sure to install the instrument 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 instrument with damaged or substandard wiring. 
4.  Do not operate the instrument if it has received a sharp blow, been 
dropped, or otherwise damaged in any way. If the instrument is 
damaged, see the Warranty on page ii. 
5.  Do not disassemble the instrument. It contains no user-serviceable 
parts. See the Warranty on page ii for instructions on obtaining 
service. Attempting to service the  instrument 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 instrument before attempting any maintenance or cleaning or 
working on any circuits connected to the instrument. Turning off 
controls will not reduce this risk.
