Intelligent Parallel Minimum Redundancy
This is the minimum Number of Redundant Modules that the system will
allow before bringing one or more modules back to normal operation and
terminating Intelligent Paralleling.
Intelligent Parallel Mode
This setting gives the user the ability to choose between different energy
consumption modes while Intelligent Paralleling is active and module is in
standby.
Intelligent Parallel Operation State This setting is used to enable or disable Intelligent Paralleling.
Intelligent Paralleling Shutdown Delay
This is the length of time the conditions for module standby must remain
satisfied before the module goes into standby.
Internal Bypass Breaker (CB3) Internal bypass breaker (CB3)
Internal Communications Failure
The control has detected a communication failure of a component on the
internal communication bus
Inverter Failure Inverter failure - inverter output is off
Inverter Inhibit - External Restart of the inverter is inhibited by an external signal
Inverter Off - External Inverter is off (operation is inhibited) due to external signal state
Inverter On/Off State inverter on/off state
Inverter Output Qualification Status inverter output qualification status
Inverter Overload Phase A Inverter is operating with an overload on phase A
Inverter Overload Phase B Inverter is operating with an overload on phase B
Inverter Overload Phase C Inverter is operating with an overload on phase C
Inverter Overload Time Remaining The calculated time remaining before inverter shutdown
Inverter Shutdown - Overload The inverter has shutdown due to a sustained overload
Inverter Static Switch SCR Short
The system has detected a short across one or more inverter static switch

LBS Active - Master
This UPS system has been selected as the functional Master Load Bus
Synchronization (LBS) system.
LBS Active - Slave
This UPS system is synchronized to the output bus of the UPS system that
has been selected as the Master Load Bus Synchronization (LBS) system.
LBS Active The Load Bus Sync option is active
LBS Inhibited
The system has detected that conditions to perform Load Bus Sync are not
satisfied
Leading Power Factor The leading output Power Factor has fallen below a specified value
Loss of Redundancy
The multi-module collection doesn't have enough modules to redundantly
support the load
