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
Comms
Shutdown
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 Setting 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
Inverter Sync
Range
Sets the range of inverter synchronization for bypass frequency operation and availability
Remote
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
Set RS232
Protocol
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
Command
Password
Users can change the command 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.
