> The ECC 320 may only be installed, started up and serviced by quali-
ed electricians in accordance with the applicable national regulations.
See: „3.2 Qualifikation des Personals“ auf Seite 7.
> Before connecting the ECC 320, ensure that no voltage is present or take
suitable protective measures (see „7.1 De-Energizing the Supply Line“ on page 22
and „7.5 Disconnect the ECC 320 from the Power Supply“).
> For the correct dimensioning of the AC supply line, see:
„7.4.1 Cable Cross-Sections of Main AC Supply Line“ on page 23.
> See section „7.6.2 Connection Data for Cable Entry Plate“ for the available outer
cable diameters.
> Connect L1/L2/L3 according to the terminal labeling.
• Tighten screws with tightening torque = 28 Nm.
• Additionally observe the manual of the manufacturer Siemens:
see „7.4.2 Installation Manual for Fuse Switch Disconnector“ on page 23.
• For maximum cable cross section see 7.7.2 on page 28.
> The dimensioning of the protective conductor of the AC supply line (PEN)
is based on ÖVE/ÖNORM E8001-1:2010, Table 20-2. When using a copper
strip, a minimum cross-section of 50 mm2 is prescribed.
• See section 7.3 on page 22 for 4- or 5-pole connection.
• Observe the specifications in sections 7.4.4 on page 25 and 7.4.5 on page 25.
> Check that L1/L2/L3/PE-N are tightened to the correct torque.
> AC main supply line (400 V) successfully connected.
