How to Test and Tag a UPS

We've found that a UPS (Uninterrupted Power Supply) is an item that's often not tested correctly to Australian Standards.

The most common reasons for this: either having trouble finding the earthing point, or incorrectly thinking that a UPS only requires one earthing point checked, instead of testing all of them.

Although it can be difficult to test under some circumstances, it's important to remember:

• Every single outlet of the UPS needs to be tested using a Class I Test
• You can use a Flat Tipped Probe that'll fit within the earth socket (they can be used with most interchangeable test leads)
• Alternatively, you can test the earth through the appliance while it's plugged into the UPS
• We suggest you turn the Insulation Resistance down to 250V (or if the UPS is surge protected)
• We suggest you perform an additional Leakage Current test
• If you attempt an extension lead test, the polarity will fail
