Connection without terminal box

If the machine was ordered without terminal box (where the cables are simply brought out of
the motor), then the proper connection must be made in an external terminal box.
Incorrect dimensioning
Faults can occur if the appropriate technical data is not complied with when connecting up.
For instance, degree of protection, minimum air and creepage distances. These faults can
result in eventual or immediate death, serious injury or material damage.
● Ensure that the external terminal box is dimensioned according to the data on the rating
If the motor has been ordered with brought-out leads, in this case you must comply with the
relevant conditions for Zone 2. It is assumed that the buyer, the installer and users of the
installation are familiar with these conditions and will carefully observe them.
