DC input monitor
DC input monitor supervises DC input voltage and DC input current.
• The DC input voltage is the voltage measured on the panel side of the DC contactor.
DC input voltage and power can be monitored with parameters 208.01 Input voltage
and 208.03 Input power.
• The measured DC input current is used for detecting DC input overcurrent and
reverse DC input currents. The power module input currents can be monitored with
parameter 208.04 Input current.
See also, DC input specific current monitoring (available with G417 option) on page 40.
DC input voltage monitor
The module monitors that the voltage on the DC input side is larger than the minimum limit
and smaller than the maximum limit when the inverter starts to operate. The DC input
voltage monitor also checks the polarity of the DC input voltage. If a large negative voltage
is detected in the input a warning is displayed to indicate an improper connection of the
DC cables.
