3.5.3 Insert the socket guard into the X102 service socket.
See item X102 in Fig. 3 - 2, page 157.
For the USA version, insert the socket guard into the X102 service socket.
3.5.4 Replacing the main power cable
CAUTION
The electrical cables to each individual placement machine must be clearly identified and easy to
allocate without doubt. The regulations of the country in which the machine is operated apply.

Crimp a ferrule onto each end of the wire.
Loosen the nuts on the angled cable gland (item 2 in Fig. 3 - 8).
Fold up the angled cable gland.
Feed the power supply cable through the angled cable gland to the terminal panel X100 (see
X100 in Fig. 3 - 9
).
Connect the cable to the terminal and ensure that it has a sufficient bending radius. The wires
must not be kinked.
Fold up the angled cable gland (item 2 in Fig. 3 - 8) and tighten the nuts hand-tight.
