Note that the permissible continuous current for devices with a
rated operational current I
mounting and the ambient temperature.
See following Sections.
￫
Currents under the minimum current specified in the table 6will
not be detected by the motor protection. It is therefore not per-
missible to operate the motor 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.
WARNING

The plug-in motor starters are usually used in conjunction with
busbar adapters, where several starters have a mutual external
short-circuit protective element. To protect the individual motor
starters, these contain an internal fuse for each phase.
These fuses are accessible by opening a flap on the left side of
the device.
The fuses must only be replaced with the device not plugged in
(disconnected from the power supply).
The fuses that must be used are listed in ￫ section 9.2,
"Fuses", page 55.
