A key component installed within the control panel at all stations is a UPS (Uninterruptible Power Supply). In case of power outage, the UPS provides reserve power to keep the control equipment running until power is restored or until the battery depletes — whichever occurs first.

NRI’s preferred UPS for water towers and small pump/lift stations is presently the 3S Series by Eaton. Like many UPS manufacturers, Eaton ships its 3S-series units from the factory with the internal battery disconnected.  Why?  Because if the battery were connected, and the UPS inadvertently switched ON during bumpy transit, then the UPS would start beeping — and delivery drivers don’t like packages that start beeping, for obvious reasons!

Therefore, when your new UPS arrives, you will need to connect the battery terminals.  The following photos illustrate the sequential steps required to connect the battery:

Are you interested in implementing or upgrading a battery-backed power system at one or more of your critical pumping or water treatment stations?  We offer experience in this area — and much more. Give us a call, and we’ll be glad to discuss this with you in further detail.
