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

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.
