2. Connect wires 1 to 3 and the protective conductor
(GN/YE) of the connection cable 1 684 465 810 in
the motor terminal box (see Fig. 115).
3. Attach the cover of the motor terminal box.
4. Tighten the union nut of the cable gland
(Fig. 114, item 2).
5. Insert the connection cable 1 684 465 810 through
the sealing gasket and the gasket opening into the
electric compartment
(see cable installation in Fig. 105, item 4).
! If cables U/T1, V/T2 and W/T3 are attached at the
wrong points, the three-phase motor will run in-
correctly, and the pump will accumulate little to no
pressure.
6. Attach connecting cable 1 684 465 810 of the
three-phase motor M1 to the power terminals of the
frequency converter A13 as follows:
$ Wire 1 to terminal U

1 684 465 810 to the adapter plate of the frequency
converter A13. To do this, attach the securing clip
(Fig. 116, item 1)to the adapter plate in the area
where the sheathing of the connectingcable
1 684 465 810has been stripped.
