Note!
The motor starters are designed for motor powers between 0.75 kW and 3 kW
and rated currents between 1 A and 7 A.
If motors with powers < 0.75 kW or rated currents < 1 A are operated on the
motor starters, please observe the following:
ƒ The internal I 2 xt monitoring cannot be used because of the low current.
– Switch off the internal I 2 xt monitoring (C0121 = 0).
– Use a PTC or thermal contact (NC contact) to monitor the motor
temperature
– Appropriate external motor protection switches can be used in addition.
ƒ The mains phase failure control can respond during operation, although no
main failure has occurred.
–
Deactivate the mains phase failure control (C0122 = 3) to ensure that the
drive will not switch off with an error message.
