For all unit types, external pre-fuses must be fitted in
the mains supply to the frequency converter. For UL/
cUL applications with a mains voltage of 200-240 Volt,
use pre-fuses type Bussmann KTN-R (200-240 Volt)
or Ferraz Shawmut type ATMR (max. 30A). For UL/
cUL applications with a mains voltage of 380-480 Volt,
use pre-fuses type Bussmann KTS-R (380-480 Volt).

Mains connection
Please note that at 1 x 220-240 Volt the neutral wire
must be attached to terminal N (L2) and the phase wire
must be connected to terminal L1 (L1).

NB!
Please check that the mains voltage fits
the mains voltage of the frequency con-
50
verter, which can be seen from the nameplate.
400-Volt units with RFI-filters may not be
connected to mains supplies in which the
voltage between phase and earth is more
than 300 Volts. Please note that for the IT
mains and the delta earth the mains voltage can exceed 300 Volts between phase
and earth. Units with type code R5 can be
connected to mains supplies with up to
400 V between phase and earth.
See Technical data for correct dimensioning of cable
cross-section. See also the section entitled Galvanic
isolation for further details.
