Safety Earth Ground

This is a Safety Class I product (provided with a protective earthing terminal). An uninterruptible safety earth ground must be provided from the main power source to the product input wiring terminals, power cord, or supplied power cord set. Whenever it is likely that the protection has been impaired, the product must be made inoperative and secured against any unintended operation.

Before Applying Power Verify that the product is configured to match the available main power source as described in the input power configuration instructions in this manual. If this product is to be powered by auto-transformer, make sure the common terminal is connected to the neutral (grounded) side of the ac power supply.
