Uninterruptible Power Supply (UPS) maker, Alliance Power Conversion (APC), has recalled some of its Back-UPS CS systems after half a dozen melted. The recall potentially affects 2.1 million units sold worldwide.
Specifically, two models have been recalled: the Back-UPS CS 350 and the Back-UPS CS 500, both in 120 and 230 volt capacities. Both models were made between November, 2000 and December, 2002. If you have one of these units, check the serial numbers. Units affected by the recall include those with the following serial number ranges: AB0048 through AB0251; BB0104 through BB0251; JB0125 through JB0251
If the serial number ends in "R", it's not part of the recall, APC said. Users whose power supplies have been recalled are encouraged to call log onto the APC website at http://www.apcc.com/rely/index.cfm and register the unit or call 1800 652 725.
The units were sold primarily through computer and electrical distribution, catalogue and retail outlets.
APC has received eight reports worldwide of units overheating. The company said the problem causing this recall results in the outer case of the UPS melting. Nobody has been hurt by the problem, although it has caused minor property damage in three recorded incidents.
