Inspecting for unsafe conditions
Use this information to help you identify potential unsafe conditions in an IBM product that you are working
on.
Each IBM product, as it was designed and manufactured, has required safety items to protect users and
service technicians from injury. The information in this section addresses only those items. Use good
judgment to identify potential unsafe conditions that might be caused by non-IBM alterations or attachment
of non-IBM features or optional devices that are not addressed in this section. If you identify an unsafe
condition, you must determine how serious the hazard is and whether you must correct the problem before
you work on the product.
Consider the following conditions and the safety hazards that they present:
• Electrical hazards, especially primary power. Primary voltage on the frame can cause serious or fatal
electrical shock.
• Explosive hazards, such as a damaged CRT face or a bulging capacitor.
• Mechanical hazards, such as loose or missing hardware.
To inspect the product for potential unsafe conditions, complete the following steps:
1. Make sure that the power is off and the power cords are disconnected.
2. Make sure that the exterior cover is not damaged, loose, or broken, and observe any sharp edges.
3. Check the power cords:
• Make sure that the third-wire ground connector is in good condition. Use a meter to measure third-
wire ground continuity for 0.1 ohm or less between the external ground pin and the frame ground.
• Make sure that the power cords are the correct type.
• Make sure that the insulation is not frayed or worn.
