Why is the emergency supply period shorter than nominal value on my CertaUPS C400-010-B?
The emergency supply period might be shorter than expected due to two primary reasons: either the batteries are not fully charged, or the batteries are defective. To resolve this, ensure that you charge the batteries fully. If the issue persists, consider replacing the batteries or consulting with your dealer.
What to do if my CertaUPS UPS has no indication and no warning tone?
If your UPS shows no indication and emits no warning tone while connected to the main power supply, it could be due to: 1) No input voltage. Check the building wiring, socket outlet, and input cable. 2) An open breaker. Check the breaker.
