￫
Note that the permissible continuous current for devices with a
rated operational current I
e
of 9 A depends on the type of
mounting and the ambient temperature, ￫ section 2.5, “Lay-
out of devices with I
e
= 9 A”, page 17.
￫
Currents under the minimum current specified in table 2 will not
be detected by the motor protection. The motor must not be
operated under this value.
The motor starter itself also works if the current is under this
minimum value. This state is displayed by the flashing of both
LEDs PWR and ERR. The relay output also signals an alarm.
