Intelligent
hibernation
If this parameter is set to
Enable
, the intelligent battery hibernation
function is enabled.
Class 1 grid
hiber. time (d)
and
Class 2
grid hiber.
time (d)
Set the hibernation time based on the power grid type. In hibernation
mode, batteries are not charged or discharged, which extends the battery
lifespan.
The
Class 1 grid hiber. time
value range is 0–30 days, and the
default value is 13 days. The value 0 indicates no hibernation.
The
Class 2 grid hiber. time
value range is 0–15 days, and the
default value is 6 days. The value 0 indicates no hibernation.

are used to check whether
the cells in each battery string have the same charge voltage and
discharge voltage. When a value exceeds the specified range, an alarm is
generated.
The calculation formula is (Charge/Discharge voltage – Average
voltage)/Average voltage x 100%.
Dry Contact Settings
Set only the dry contacts that are needed. Otherwise, the UPS may not run properly.
When a dry contact card is disabled, its dry contact signals are disabled.
After a dry contact card is enabled, its dry contact signals can be displayed on the LCD.
Disable all the dry contacts for a dry contact card that is not connected and all the dry
contacts that are not used to prevent false alarms.
( ) encloses a unit, and [ ] encloses silk screen.
Specify dry contact settings on the following cards:
Dry contact card (MUE05A): provides dry contact signals for the battery grounding
failure detector, D.G., BCB box, and PDCs.
Backfeed protection board (MUE06A): provides backfeed protection signals. This board
can be enabled or disabled.
Monitoring interface card (MUS05A): provides four routes of configurable output dry
contact signals.
Dry contact extended card (MUE07A): provides two routes of input signals and one
route of output signals.
Set the dry contact parameters, as shown in
to
