1Safety
 
Application of the wrong supply voltage, connection of the instrument 
to an incorrectly wired supply outlet, or lack of proper electrical 
grounding can create a fire hazard or a potentially serious shock hazard 
and could seriously damage the instrument and any attached ancillary 
equipment.
Always use a three-wire outlet with ground connection which is 
adequately rated for the load. The installation must comply with local, 
state, and federal safety regulations.
Do not connect the instrument to the main power supply until you have 
made sure that the operating voltage is correctly set for the main power 
supply in the specific outlet in your laboratory to which the equipment 
will be connected.
