Product identification labels (ratings) can be found on the tops and sides of the cabinets, the rear of monitors, and other exterior surfaces on the equipment. Such product labels alert you to specific hazards and the level of hazard importance. The labels may also contain messages that communicate the specific hazard, the probable consequence of involvement with the hazard, and how the hazard can be avoided. In the event you are unable to identify these labels, contact your service personnel.
One or more of the product identification labels in the tables below may be on your system or peripheral equipment. Please familiarize yourself with the labels that apply to your particular system.
