Description
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.
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.
Specifies whether to enable or
disable input current limiting to
protect generators.
Limits the input current to protect
the D.G.
Description
If this parameter is set to Enable,
the output current is displayed as
0 when no load is output. The
output load rate is displayed as
3%. When this parameter is set to
Disable, the output current and
output load rate are not adjusted
to zero.
The interruption for the UPS to
transfer from normal mode to
bypass mode is 1–2 ms, and from
bypass mode to normal mode is
0–20 ms. Set this parameter
based on the output interruption
time acceptable to loads.
Cross currents occur during the
transfer between bypass mode
and normal mode, which impacts
the system. This parameter
specifies the number of transfers
between bypass mode and
normal mode within 1 hour,
which ensures system security.
