(2) “Protection Parameter” menu configured with system protection parameters
There are 9 pages under the protection parameter menu, which correspond to the following
parameter types as grid voltage protection parameter, grid frequency protection parameter, startup
& shutdown protection parameter, power grid ride-through protection parameter, active power
control, reactive power control (I), reactive power control (II), rated parameter and other
protection parameters. Click the value of each parameter name to modify.
Figure 9-5 Protection parameters
Click the "System" button, find the parameters to be changed, then click and modify the parameter
values, and then click on the "Enter" key. The protection parameters and the values that can be set
are as shown in the following table.

NOTICE:
CPS SCH1500K has 2 modules. The number of on-line modules of the inverter is
correct or not should be confirmed before inverter startup. If startup is executed when
modules are lost from the system, the danger of inverter damage might be caused.
