Question about Newpoint (200897) (DHN200897) UPS System
Posted by Anonymous on
I just bought a battery (readily available) for $16 and here is how I replaced it, but first, make sure UPS is disconnected from 120 Volt service. (Old battery number SW1233 with F connectors.)
Turn the UPS over and look for 1 tiny screw (even with the "in" telephone wire socket). Remove the screw (turn CCW). Push the button marked push, then slip a steak knife or sharp putty knife into the joint in front of the screw hole. Twist the tool enough to start the battery cover moving backward (to your left).
The battery is upside down. Lift it high enough to grab wires and pull them off the postst.
Verify battery you bought fits the housing. With UPS upside down, place battery on right side with lugs toward the power cable. Push red wire onto red post. Hold the battery upside over UPS. Push black wire onto black post.
Visually ensure the wires both run in their channels (otherwise the battery will not seat and the cover won't slide on.) Push battery into slot until it bottoms.
When the battery is bottomed properly, hold the cover about 2/3's over the battery housing, push it down, then push it toward the screw hole (to your right). If this operation, or the cover jams near the screw hole, check the battery. It must be absolutely bottomed in the slot. The cover won't go on easily even when everything is perfectly aligned.
After the cover is closed and the screw replaced, plug the UPS into a wall socket. The on/off button has a mind of its own, so ignore it. The green light may light and there is one beep. The backup yellow light may blink. The green light may stay solidly on. Pull the cord plug out of the wall. Now the UPS green light may go out and you will hear a ratcheting sound (the UPS is making AC from the 12 Volt battery current). Because you have no device plugged into a "battery-backup" plug, the UPS will shut off automatically in a few minutes.
The last test is to reconnect the plug to the wall service, then plug a monitor, a music system, or something similar into a Battery B/U connector. The green light should light. When the UPS is again unplugged, the yellow light (Backup) flashes and there is a repeating beep. Plug UPS back in. Only the green light will be on. That's it, all done.
I use Newpoint UPS to back up my telephone/modem. During a brownout, SPS powers those units almost 2 hours.
Note: This UPS is not suitable for powering or charging Laptops because the power output is too dirty.
