Safety clamp
If the galvanic isolation (PELV) between
control terminals and high-voltage termi-
nals is to be maintained, the accompany-
ing safety clamp must be fitted to VLT
2803-2815, 200-240 V, and VLT
2805-2815, 380-480 V.
Pre-fuses
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).

NB!
Please check that the mains voltage fits
the mains voltage of the frequency con-
verter, which can be seen from the name-
plate.
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 volt-
age 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.
