Electrical installation

WARNING! Risk of electric shock.
Work with electric equipment is to be carried out by a qualified electrician.
NOTE!
National and local electric regulations are to be followed.
For electrical data, see Section '5.3.2 Electrical data'. Column F1 gives the
recommended mains fuses (slow) for different supply voltages.
Column S1F gives the settings for the overload relay. These are set when the
unit is tested before delivery but should be verified when installing the unit.
The setting is equivalent to 0.58×the nominal current of the motor.
For the power circuit, control circuit and terminal connection diagrams, see the
following figures:
