Frequently Asked Questions - EN350 Minuteman
How do I connect devices to the EN350 UPS?
Plug your devices into the battery backup outlets (marked with a battery icon). The remaining outlets provide surge protection only. Ensure total load does not exceed 210W.
What is the typical backup time for this UPS?
At full load (210W), the EN350 provides approximately 10-15 minutes of backup. At half load, runtime extends to 20-30 minutes.
How long does it take to fully recharge the battery?
After a full discharge, the battery recharges completely in about 6-8 hours.
What does the audible alarm mean?
A beep every few seconds indicates the UPS is on battery. A rapid beep signals low battery. Continuous beeping indicates an overload or fault.
Can I replace the battery myself?
Yes, the battery is user-replaceable. Open the front panel, disconnect the terminals, and replace with a standard 12V 7Ah battery. Please recycle the old battery.
Is the EN350 compatible with generators?
It is not recommended to connect the UPS directly to a generator. Use a generator with stable output and allow it to run for a few minutes before connecting the UPS.
What should I do if the UPS does not turn on?
Check that the UPS is plugged into a working wall outlet and the power switch is on. If still off, try a different outlet. If no response, the battery may be dead.
How often should I test the UPS?
Perform a self-test every 3 months by unplugging the UPS from AC power while loads are connected. Verify that devices continue running and alarms sound.
Can I plug a power strip into the UPS?
No, do not plug power strips into the UPS. Connect devices directly to the UPS outlets to avoid overloading and reduce fire risk.
What is the warranty period?
Minuteman typically offers a 2-year warranty on the UPS and a 2-year warranty on connected equipment. Check your specific model confirmation.
