2. If you are not using a shield clamp, proceed as follows:
– Insert the cable into the enclosure through the cable gland.
– Strip the cable sleeve to match the length of the
cable route (A). The length of the cable route
depends on the inverter model (see images in
Section 4.1 "Overview of Interface Port and
Cable Route" on Page 8).
– Shorten the unused insulated conductors down
to the cable sleeve (C).
– Shorten the cable shield to reach the PE
connector (connector tab) (B) in the inverter and
twist it. The length to the PE connector depends
on the inverter model (see images in Section 4.1
"Overview of Interface Port and Cable Route"
on Page 8).
– Connect the flat cable connector to the cable
shield.
– Connect the flat cable connector with the PE
connector tab.
– Strip 6 mm off the insulated conductors (D).
3. Tighten the nut of the cable gland to secure the cable.
4. Installing the insulating tube:
5. For simplification the two cables can be bound together with a cable tie.
6. Install the cable with an insulating tube along the cable route to the screw terminals.
☑ The cable is installed in the inverter.
DANGER!
Danger to life through high voltage if there is a fault with the communication
cable.
• Pull an insulating tube over the wires of the used cables that
reaches up to the inverter enclosure opening. The insulating
tube must completely cover the wires inside the enclosure.
• If necessary, cut the insulating tube back to the required
length.
