Settings
Redundancy
Disabled/ Enabled. If ‘Enabled,’ the system operational parameters will
assume there is a redundant power module in the frame; if ‘Disabled’, the
system operational parameters will assume that all power modules in the
frame are not redundant.
Note: This item is closely related to the ‘Redundant alarm’ setting
Remote Shutdown
Through Comms
Ports
Disabled/ Enabled. If ‘Enabled,’ this allows the UPS output power to be
shutdown through remote communication, including the dry contacts and
Liebert IntelliSlot communication cards.
Note: This item is closely related to ‘Remote shutdown delay’
Bypass Set Enables the bypass to supply power or not
Output Frequency Sets the output frequency to allow frequency conversion operation
Output Voltage Sets the output voltage level to match the mains input voltage
Sync Range
Sets the range of inverter synchronization for bypass frequency operation
and availability
Shutdown Delay Sets the shutdown delay time for the remote signal operation
Bypass Upper
Limit
Sets the upper limit of bypass voltage operation and availability
Bypass Lower
Limit
Sets the lower limit of bypass voltage operation and availability
Guaranteed
Shutdown
Disabled/ Enabled. If ‘Enabled,’ once a low battery alarm is generated
during a battery discharge, the UPS will continue battery mode operation
until it reaches the end of discharge (EOD) setpoint, then will shutdown
output power, whether the AC mains recovers or not.
Bypass Alarm
Mode
Allows an alarm to be generated when the bypass is abnormal
Serial Comm.
Select
Because the slot 2 and the serial port on the rear panel cannot work at the
same time, you must select one of them to work. If ‘INTERFACE2’ is
selected, the slot 2 can communicate; if ‘RS232’ is selected, the serial
port can communicate.
Auto Restart Mode Allows auto restart after a EOD shutdown and AC mains returns
Auto Restart
Capacity
Sets the battery capacity limit of auto restart feature. When AC mains
power returns, the UPS will charge the battery to the specified battery
capacity before enabling output power.
Auto Restart Delay
Sets the delay time of auto restart feature. When AC mains power returns,
the UPS will start a countdown timer based upon the setting before
enabling output power.
Display Contrast Adjusts the contrast of LCD backlighting
Date and Time Sets date and time
Control Password
Users can change the control password to prevent unauthorized user
from changing any user configurable settings. The default password is
1234567. Once the password is changed, the default password is no
longer operational and users are then required to enter the new password
to enter/change any ‘Settings’ or ‘Battery settings’. If the new password is
forgotten, contact your local customer service center for steps to reset the
password back to the factory default.
Max Load Alarm
Sets a maximum load alarm. This item is closely related to ‘Max load
threshold.’
Max Load
Threshold
Sets the threshold of maximum load alarm. When the UPS loads exceed
the threshold, and the maximum load alarm is enabled, an alarm will be
generated.This item is closely related to ‘Max load alarm,’ for example, set
this item to 5.0kVA, when the UPS loads exceed 5.0kVA, an alarm will be
generated.
Redundant Alarm
Mode Allows alarm to be generated when the system loses redundant power
