6 Electrical Connection
☐ All electrical installations must be carried out in accordance with the local standards and the
National Electrical Code
Requirements for the conductors:
☐ Conductor cross-section: 0.2 mm² to 1.5 mm² (24 AWG to 16 AWG)
☐ The conductor type and wiring method must be appropriate for the application and location.
Procedure:
1.
Danger to life due to high voltages
• Disconnect the inverter from all voltage sources (see Section 8, page 58).
2. If the enclosure lid of the DC-Connection Unit is
closed, remove it as follows: Unscrew all ten screws
(TX25) and remove the enclosure lid towards the
front.
3. Set the screws and the enclosure lid aside and store safely.
4. If cable conduits are used: remove the M32 cable glands from the enclosure opening. To do
so, unscrew the counter nut from inside and remove the cable glad from the enclosure
opening.
5. If cable conduits are used: insert the conduit fitting into the opening and tighten it from the
inside using the counter nut.
6. If cable conduits are used: attach the conduit to the conduit fitting.
7. If cable conduits are used: guide the conductors out of the conduit into the inverter.
8. If the cable glands are used: remove the swivel nut from the cable gland for the
communication cable.
9. If the cable glands are used: thread the swivel nut over the network cable.
10. If the cable glands are used: remove the two-hole cable support sleeve from the cable gland.
11. If the cable glands are used: remove the sealing plug from one of the enclosure openings of
the two-hole cable support sleeve and insert the conductor into the enclosure opening.
12. If the cable glands are used: press the two-hole cable support sleeve with the conductors into
the cable gland and route the conductor to the communication assembly in the DC connection
unit. Ensure that any unused enclosure openings of the two-hole cable support sleeve are
sealed with sealing plugs.
13. Strip off the conductor insulation by max. 9 mm (0.35 in).
