What to do if PROLiNK MASTER II is overloaded?
- JJustin ReyesAug 29, 2025
If your PROLiNK UPS displays warning code 09, it means the UPS is overloaded. Remove some of the devices connected to the UPS to reduce the load. If the UPS locks in Bypass mode after repeated overloads, turn off the UPS, remove excess load, and then turn it back on.
