ON-BYPASS
This mimic indicates that the load is being
supplied via the bypass line, and it is the
normal indication if the system is operating
in 'ECO' mode.
When the system is normally operating in
'on-inverter' mode, this state usually
indicates that the load has either been
manually transferred, transferred due to an
output overload that has caused the
inverter to shut down, or transferred due
the loss of module redundancy.
If the transfer to bypass is due to an
inverter fault, the inverter icon will be red.
1. The rectifier is working normally.
2. The battery is charging.
3. The inverter is turned off or shut down.
4. The parallel switch is closed and
connecting the UPS output to the
bypass supply
mains).
ON MAINTENANCE BYPASS
This mimic indicates that the (optional)
maintenance bypass isolator is closed and
the load is connected to the bypass supply
through both the 'maintenance' and 'static'
bypass lines in parallel.
1. The rectifier is working normally.
2. The battery is charging.
3. The Inverter is turned OFF.
4. The parallel switch is shown closed. At
the module level, if the module's output
isolator is now opened, the UPS
module is totally isolated from the UPS
output and can be replaced or serviced
without affecting the rest of the UPS
system.
