Danfoss VLT 2800 Design Guide

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

WARNING
Ensure that the mains voltage fits the mains voltage of
the frequency converter, which can be seen from the
nameplate.
WARNING
Do not connect 400 V units with RFI-filters to mains
supplies in which the voltage between phase and
ground is more than 300 V. For the IT mains and the
delta ground, the mains voltage can exceed 300 V
between phase and ground. Units with type code R5 can
be connected to mains supplies with up to 400 V
between phase and ground.
See chapter 5.1.1 Galvanic Isolation (PELV) for details on
correct dimensioning of cable cross-section.

Motor Connection
Connect the motor to terminals 96, 97, 98. Connect ground
to terminal 99.
See chapter 5.3 General Technical Data for correct
dimensioning of cable cross-section.
