functions, such as protection against
overcurrent,
overvoltage, undervoltage,
overtemperature, phase loss, and overload.
Speed tracking restart
Used to implement impact-free smooth startup
for rotating motors.

Others
Installation mode
Wall and rail installation for the 1PH 220V
(≤2.2KW) VFD models.
Wall and flange installation for the 1PH 220V
(4kW) VFD model.
EMI filter
1PH 220V (4kW) VFD model can satisfy the
requirements of IEC 61800-3 C3, other models
can satisfy the requirements of IEC 61800-3 C3
by installing optional external filter. The whole
series can satisfy the requirements of IEC
61800-3 C2 by installing optional external filter.
Temperature of running
environment
-10–+50°C; derating is required if the ambient
temperature exceeds 40°C.
Altitude
Below 1000m.
When the altitude exceeds 1000m, derate by 1%
for every increase of 100m.
When the altitude exceeds 3000m, consult the
local Kruger dealer or office for details.
