4.4.3 Replacing the socket with earthing contact
See item BU1 in Fig. 4 - 2, page 112.
Å Remove the cover flap over the socket with earthing contact.
Å Remove the socket insert.
Å Detach the wires.
Å Attach the wires to the US standard socket.
Å In particular, make sure that the yellow-green PE conductor is correctly connected to the
earthing contact (PE).
Å Fix the socket insert and cover flap in place.
4.4.4 Replacing the main power cable
The main power cable is connected to the U, V, W, N and PE terminals on terminal strip X1 (see
item X1 in Fig 4 - 2
, page 112).
Å Detach the wires of the main power cable from the U, V, W, N and PE terminals.
Å Detach the cable clamp from the cable holder.
Å Pull the cable out of the cable holder.
Å Push the main power cable (6 mm²) through the cable holder as far as the terminals on X1.
PLEASE NOTE: 4
Make sure that the cable bending radius is sufficient to prevent the wires being bent. 4
Å Connect the main power cable to the terminals on X1:
Wire 1 to U on X1,
Wire 2 to V on X1,
Wire 3 to W on X1,
Wire 4 to N on X1 and
Wire 1 to PE on X1.
(See circuit diagram 00119085-010101LD4, page 2)
Å Tighten the cable clamp.
