UPS5000-E-(20 kVA-80 kVA)
User Manual (Integrated UPS, 208 V)
Issue 04 (2020-03-12)
If a top outlet fan is configured, check the fan running status after enabling this
parameter.
EOD restart
The UPS transfers to battery mode when the mains becomes abnormal. When batteries
reach the EOD threshold and the bypass is disabled and EOD restart is enabled, the
UPS will restart as soon as the mains resumes.
If EOD restart is disabled, clear the alarm manually or enable the function to restart the
UPS.
EOD restart delay (min)
If EOD restart is set to Enable, the UPS starts working after EOD restart delay when
the mains recovers from an EOD power failure. The value range is 1-1440 min, and the
default value is 10 min.
Inverter async. alarm
Specifies whether the Inverter async. alarm is displayed when the inverter does not
track the bypass input. The normal power supply is not affected no matter whether you
set the parameter to Enable or Disable.
Bus overvoltage recovery
Specifies whether to automatically clear the alarm and restart the power module when
the rectifier or inverter shuts down due to a bus overvoltage alarm. If Bus overvoltage
recovery is set to Enable, the bus overvoltage alarm is automatically cleared, and the
rectifier and inverter automatically start when the bus voltage recovers (less than 420 V)
within Bus overvolt. recovery time. When Bus overvoltage recovery is set to Disable,
the bus overvoltage alarm cannot be automatically cleared, and the rectifier and inverter
cannot automatically start. The default value is Enable.
Bus overvolt. recovery time
If Bus overvoltage recovery is set to Enable, the bus overvoltage alarm is automatically
cleared, and the rectifier and inverter automatically start when the bus voltage recovers
(less than 420 V) within Bus overvolt. recovery time. The default value is 5s.
Capacitor failure detection
The default value is Enable. When Capacitor failure detection is set to Enable, the
power module performs inverter capacitor fault detection based on the settings of
Capacitor failure detection upper limit and Capacitor failure detection lower limit.
If the power module determines that the inverter capacitor is faulty, it shuts down the
inverter to prevent the fault from expanding.
Capacitor failure detection upper limit (A)
The value range of Capacitor failure detection upper limit is 10–13 A and the default
value is 13 A. When the inverter capacitor current exceeds the current specified by this
parameter, the power module determines that the inverter capacitor is faulty and shuts
down the inverter.
Capacitor failure detection lower limit (A)
The value range of Capacitor failure detection lower limit is 0–2.5 A and the default
value is 2.5 A. When the inverter capacitor current is lower than the current specified by
this parameter, the power module determines that the inverter capacitor is faulty and
shuts down the inverter. If Capacitor failure detection lower limit is set to 0 A, the
power module does not perform inverter capacitor fault detection.
Input cur. limiting
This parameter specifies whether the UPS controls input current limiting. When this
parameter is set to Enable, electric generator overload due to excessively large input
current can be prevented. The default value is Disable.
