Minuteman UPS E1500RM1U, E1000RM1U, E700RM1U user manual Overload

English

OVERLOAD

When the amount of load attached to the UPS exceeds its power rating, the Overload LED will illuminate and the UPS will sound a constant alarm. This alarm will remain on until the excess load is removed or the UPS’s self protec- tion circuit shuts the UPS down.

WEAK/BAD BATTERY

The UPS automatically tests the battery’s condition and will illuminate the Weak/ Bad Battery LED and sound the alarm. This alarm will be repeated until the batteries pass a self test. If the battery is weak, bad or disconnected, the Weak/Bad Battery LED will illuminate and the alarm will beep three times every five-minutes until the battery is reconnected or replaced. It is recommended that the UPS be allowed to charge overnight before performing a battery test to confirm a Weak/Bad Battery condition.

NOTE: If the UPS has a Weak/Bad Battery Alarm after reconnecting or replac- ing the batteries, the user must initiate a self test to clear the Weak/Bad Bat- tery Alarm. To initiate a self test see section 4 "SELF TEST".

COMMUNICATIONS PORTS (RS232 and USB)
