UPS Maintenance
(OP)
Hi all,
What are the recommended UPS maintenance? Here i am referring to Inverters and Chargers only.
We are using AEG Saft Protect Inverters and Profitec Chargers. They consists of mainly electronics cards, capacitors and the usual. I am not too sure how to maintain a system that depend mainly on electronic cards.
I heard before that harmonic measurement is one sapect of UPS maintenance, but how important is it?
Please help, thanks!

RE: UPS Maintenance
Otherwise, some of the following may help:
1. Perform a general visual inspection to look for the obvious such as: smoky deposits, odor, charred parts, arcing contacts or connections, loose connections, noisy cooling fan motor, or leaky blistered capacitors.
2. Yearly do a infrared scan.
3. Monthly check the ac ripple on the dc voltage output of the battery charger (will give indication of capacitor breakdown and/or firing circuit problems).
4. Clean units to keep dust build up to a minimum. (heat is an enemy of electronics)
that's a start.

RE: UPS Maintenance
is the supplier or manufacturer offers maintenance agreement?...sometimes it is worth getting it aside from the regular maintenance work you can see on the manual..

One thing more,
usage of Termo cam as a conditmonitoring action can be usefull.

Checking the semi conductors for leakage current ( scr or xistors) is one way to find components that may need replacing before a compleate failour.
