COIL CHANGING
1. Remove Overlaod Relay/Contactor assembly from enclosure, after loosening the two mounting plate screws.
2. Slacken off screws at L3 and 13 and withdraw wiring.
3. Slacken off screws at T1, T2 and T3.
4. Tilt overload away from contactor and unclip mouldings to release Overload Relay from Contactor.
5. Slacken off screws at 14, L1, A1 and A2 to remove wires.
6. Undo slotted screws located below terminals L3 and T2.
7. Seperate top and bottom halves of Contactor and withdraw coil assembly.
8. Fit new coil assembly noting that the printing on the moulding is positioned at the top of the Contactor.
9. Re assemble in the reverse order ensuring that all wires are re attached to their correct terminals. See table on
front page. For slotted contactor assembly screws (item 6) re tighten to 1.2 Nm.
