FANUC auxillary battery module IC693ACC302

Operating Notes

This unit should not be serviced by the user. If it requires maintenance or testing, it should be conducted by a trained professional who is competent in electrical safety practices. PDF Electric and Supply does offer repair services. There is a 1-Amp fuse sealed inside the battery pack. This fuse will open in the case of short-circuit or severe overload. If you think the fuse has opened, the unit will need to be tested as follows:

Turn off the PLC power.Unplug the battery.

Use a volt meter to check the connector pins on the battery cable for any voltage.

If there is power, the fuse is not open. If there is no voltage, the fuse is most likely open. In this case, the unit will need replacement.

Date Codes

On the front of the auxiliary battery module you can find the date code. This consists of three digits. The first number is the year of manufacture whereas the last two digits are the fiscal week of manufacture.

For example, a date code of 315 would indicate the battery was manufactured in fiscal week 15 of 2003.

These units have a relatively short shelf life of approximately seven years. For this reason, any battery packs that have been in storage for a long type should be disposed of.

Safe Disposal

At the end of its life, ensure that all battery packs are disposed of safely. Follow the guidelines for this in the Material Safety Data Sheet (MSDS) that was included with the product.
