Select the components to connect, according to the descriptions below, from the association tables on pages 60525/2 to 60525/11.<br />
(1) For type 2 coordination (according to IEC 60947-4-2), install fast-acting fuses to ensure that the starter will be protected in the event of a short-circuit.<br />
(2) Insert a transformer if the line voltage is different to that defined for the control circuit (see page 60521/2).<br />
(3) Assign logic input LI3 to "activate the adjustment functions of the 2 nd motor".<br />
(4) Assign relay R1 as the "isolating relay". Beware of the operating limits of the contacts (see Characteristics page 60521/2), for example when connecting to high<br />
rating contactors.<br />
