When running turn on the fan, after stop for 30 seconds
turn off the fan.

When power on turn on the fan, after power off turn off the
fan.
2
When running and the heat sink temperature exceeds
60℃ turn on the fan, under 40℃ turn off the fan.
3
When the heat sink temperature exceeds 60℃ turn on
the fan, under 40℃ turn off the fan.
Note: According to the environmental conditions of the inverter installation, if the fan can be set reasonably to run as
little as possible, the life of the fan can be extended.
5.7.6 Maintenance alarm function

Maintenance alarm function

When the multi-function digital output terminal function selection (03-11 (P.85)) is equal to 18, it is the maintenance
alarm function. That is, when the number of operating days of the inverter reaches the setting value of the
maintenance alarm function 06-17 (P.261) value, the inverter multi-function relay will output a signal.

Short circuit to ground protection
 The short circuit to ground detection when start is only implemented after the start signal is input to the inverter.
 06-18 (P.280) is used to set short circuit to ground protection function when start or not, the ground leakage
current detection during operation is set by 06-19 (P.282)
 If short circuit to ground detection when start is selected, and the output short-circuit current to ground is detected,
and the percentage of the short-circuit current corresponding to the rated current exceeds 06-19 (P.282), the
inverter stops output and alarm GF.
