AC cabling connection
WARNING! Do not do electrical work on the unit unless you are a qualified
electrician. Obey the instructions in Chapter Safety on page 11 . Failure to obey
the safety instructions can cause injury or death, electromagnetic interference and
equipment malfunction.
For information on the AC output specifications, refer to Technical data on page 123 .
To connect the AC cable:
1. Isolate the inverter from all power sources. Refer to Inverter isolation on page 16 .
2. Put the AC cable through the AC connector housing. If the outer diameter of the cable is
14...26 mm, use a suitable reducer seal. Refer to Recommended AC output cable types
on page 37 .
Note that with aluminium cables, you must remove the non-conductive oxide film from the
end of the conductors with a blade, and then immediately dip the conductors into a non-
acid and non-alkali, that is, neutral vaseline. You must repeat this procedure, if you
connect the conductors again.
3. Remove 90 mm of the outer insulation jacket
from the AC cable.
4. Remove 19 mm of the insulation jacket of each
conductor.
5. Align the conductors with approximately 15 mm
between them. This makes it easier to install the
conductors into the AC terminals.
6. Attach non-insulated wire-end sleeves. Insulated
sleeves can cause damage to the AC connector.
7. If the cable shield is the PE conductor, mark it
with insulation tape.
8. Install the conductors into the L3, L2, L1, N and
PE terminals. You can install the phase
conductors in any order.
9. Tighten the terminal screws to 4…4.5 N·m.
