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.
