66 Planning the electrical installation
Planning the installation of equipment connected to the
rotor cable
Safety switches, contactors, connection boxes, etc.
To minimize the emission level when safety switches, contactors, connection boxes or
similar equipment are installed in the rotor cable between the converter and the generator:
• EU: Install the equipment in a metal enclosure with 360° grounding for the shields of
both the incoming and outgoing cables, or connect the shields of the cables otherwise
together.
• US: Install the equipment in a metal enclosure in a way that the conduit or rotor cable
shielding runs consistently without breaks from the converter to the generator.
Bypass connection
WARNING! Never connect the power supply to the converter rotor-side terminals
U2, V2 and W2. Input voltage applied to the U2, V2 and W2 terminals can result in
permanent damage to the unit.
