4. Thread the AC cable through the cable gland of the AC connection:
• If the external diameter of the cable is
5mm to 7mm, thread the AC cable
through the cable gland directly.
• If the external diameter of the AC cable is
8mm to 13mm, first remove the inner
sealing ring from the cable gland and then
thread the AC cable through the cable
gland. When doing so, ensure that the
outer sealing ring is positioned correctly in
the cable gland.
5. Dismantle 70mm of the AC cable.
6. Shorten L and N by 5mm each. Thus, the grounding conductor will be released from the
connecting terminal plate last when tensile load is applied.
7. Strip 15mm of the insulation of L, N and the grounding conductor.
8. Connect L, N and the grounding conductor to
the connecting terminal plate for the AC
connection in accordance with the labeling.
When doing so, ensure that the conductors are
plugged completely into the terminals up to the
insulation.
Useful hint: To release the conductors from the
terminals, the terminals must be opened. To do
this, stick a flat-blade screwdriver (blade width:
3mm) as far as it can go into the rectangular
opening behind the terminal.
9. Ensure that all terminals are allocated to the correct conductors.
10. Make sure that all conductors are securely in place.
