User Manual
Input Parameter Settings
Set input parameters, as shown in
Figure 4-36 Input Param. screen
Issue 02 (2016-01-20)
Limit the input current to protect the D.G. The value can be 50%–200%, 200% by
default.
No-load output shows zero
If this parameter is set to Enable, the output current and load ratio will be displayed as 0
in the case of zero load. If this parameter is set to Disable, the output current and load
ratio will not be displayed as 0 in the case of zero load.
It is recommended that you retain the default input parameter settings.
D.G. mode
Enable or disable D.G. mode. Set this parameter when a D.G connects to the input PDC.
Select Enable when a D.G. is detected over dry contacts.
D.G. power limiting (kVA) and D.G. charger power ratio (%)
Control the input current and current limiting value to address instantaneous load impact
and to enhance the work with the D.G. The D.G. power limiting value range is 0–5000
kVA, and the default value is 800 kVA for the UPS5000-E-600 kVA and 1000 kVA for
the UPS5000-E-800 kVA. The D.G. charger power ratio value range is 0%–100%, and
the default value is 0%.
Intra-rack power module start delay (s) and Inter-rack power module start delay (s)
The two parameters enable the UPS to control the interval that each rack (or module)
transfers from battery mode to normal mode, which reduces the impact on the generator
or power grid. In the case of battery undervoltage, the system automatically shortens the
delay for transferring to normal mode to 1/8 of the normal delay to accelerate the transfer
and prevent battery overdischarge. Intra-rack power module start delay (s) can be set
to a value ranging from 0.5 to 120. The preset value of Intra-rack power module start
delay (s) depends on the preset number of power modules. The preset value is 2.0, 1.0,
and 0.5 for 1–5, 6–10, and 10–20 power modules respectively. Inter-rack power
module start delay (s) can be set to a value ranging from 2 to 120. The preset value of
Inter-rack power module start delay (s) is 5.0. The start delay of a module in a rack
