6 Electrical Connection
Requirements:
☐ The technical requirements of the multifunction relay must be met (see Section 10 "Technical
Data", page 62).
☐ All electrical installations must be carried out in accordance with the local standards and the
National Electrical Code
Requirements on･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 56).
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. When using conduits, perform the following steps:
• Remove the M32 cable glands from the enclosure opening. To do so, unscrew the
counter nut from the inside and remove the cable gland from the enclosure opening.
• Insert the conduit fitting into the opening and tighten from the inside using the counter nut.
• Attach the conduit to the conduit fitting.
• Guide the conductors from the conduit into the inverter.
5. When using the cable glands, perform the following steps:
• Remove the swivel nut from the cable gland for the communication cable.
• Thread the swivel nut over the network cable.
• Remove the two-hole cable support sleeve from the cable gland.
• 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.
• Press the two-hole cable support sleeve with the conductors into the cable gland and
guide 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.
6. Strip off the conductor insulation by max. 9 mm (0.35 in).
