VI 2335 Operators

Power Source
This product is intended to operate from a power
source that does not apply more than 250 volts rms
between the supply conductors or between either supply
conductor and ground, A protective ground connection
by way of the grounding conductor in the power cord is
essential for safe operation.
Grounding the Product
This product is grounded through the grounding con
ductor of the power cord. To avoid electrical shock, plug
the power cord into a properly wired receptable before
connecting to the product input or output terminals. A
protective ground connection by way of the grounding
conductor in the power cord is essential for safe operation.
Danger Arising From Loss of Ground
Upon loss of the protective-ground connection, all
accessible conductive parts (including knobs and controls
that may appear to be insulating) can render an electric
shock.
Use the Proper Power Cord
Use only the power cord and connector specified for
your product.
Use only a power cord that is in good condition.
For detailed information on power cords and con
nectors see Figure 2.
Use the Proper Fuse
To avoid fire hazard, use only a fuse of the correct type,
voltage rating and current rating as specified in the parts
list for your product.
Do Not Operate in xplosive Atmospheres
To avoid explosion, do not operate this product in
an explosive atmosphere unless it has been specifically
certified for such operation.
Do Not Remove Covers or Panels
To avoid personal injury, do not remove the product
covers or panels. Do not operate the product without the
covers and panels properly installed.
