Description
D.G. ECO BPM
supply
Specifies whether ECO bypass power supply is allowed in D.G.
mode. If this parameter is set to
Enable
, the system can enter ECO
bypass mode when the D.G. supplies power to the bypass and the
ECO function is enabled. If this parameter is set to
Disable
, the
system cannot enter ECO mode when the D.G. supplies power to
the bypass. The default value is
Enable
.

Description
D.G. mode
Set this parameter to
Enable
when a D.G. connects to the input PDC.
The UPS enters the D.G. mode when a D.G. is detected over dry
contacts. The default value is
Disable
.
D.G. power
limiting (kVA)
and
D.G.
charger power
ratio (%)
Set these two parameters to control the valid input current and limiting
input current, which prevents load impact and facilitates better
cooperation between the UPS and the D.G. The value range of
D.G.
power limiting (kVA)
is 0–5000 kVA. The default value is 600 kVA
for the 400 kVA/500 kVA UPS, and the default value is 800 kVA for
the 600 kVA UPS, and the default value is 1000 kVA for the 800 kVA
UPS. The value range of
D.G. charger power ratio (%)
is 0%–100%,
and the default value is 0%.
Intra-rack
power module
start delay (s)
and
Inter-rack
power module
start delay (s)
These 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.
