Danger!
To ensure explosion-proof operation, the motor-protective
relay may only be reset/switched on manually, or
automatically via a control interlock circuit for the motor
or electrical machinery, after the bimetallic release has
cooled down.
Resets may be carried out at the installation or by trained
personnel in the control room.
j
Danger!
Particularly in Ex e applications, an automatic restart must
be prevented after an interruption of the control voltage.
This is prevented safely by means of the latching function
of the power relay.
