General Safety Considerations

Safety Earth Ground

This is a Safety Class I product (provided with a protective earthing ground

incorporated in the power cord). The mains plug shall only be inserted in a socket

outlet provided with a protective earth contact. Any interruption of the protective

conductor, inside or outside of the instrument, will make the instrument dangerous.

Intentional interruption is prohibited.

Always use the three-prong AC power cord supplied with this product. Failure

to ensure adequate grounding by not using this cord may cause product

damage.

Before Applying Power

If this product is to be energized via an autotransformer make sure the common

terminal is connected to the neutral (grounded side of the mains supply).

This product is designed for use in Installation Category II and Pollution Degree 2.

Servicing

These servicing instructions are for use by qualified personnel only. To avoid

electrical shock, do not perform any servicing unless you are qualified to do so.
