Planning the electrical installation65ConduitWhere conduits must be coupled together, bridge the joint with a ground conductorbonded to the conduit on each side of the joint. Bond the conduits also to theconverter enclosure. Use separate conduits for input power, generator, brakeresistors, and control wiring. When conduit is employed, type MC continuouscorrugated aluminium armor cable or shielded cable is not required. A dedicatedground cable is always required. Do not run generator wiring from more than oneconverter in the same conduit.Armored cable / shielded power cableSix conductor (3 phases and 3 ground) type MC continuous corrugated aluminiumarmor cable with symmetrical grounds is available from the following suppliers (tradenames in parentheses):• Anixter Wire & Cable (Philsheath)• BICC General Corp (Philsheath)• Rockbestos Co. (Gardex)• Oaknite (CLX).Shielded power cables are available from Belden, LAPPKABEL (ÖLFLEX) andPirelli, among others.Power factor compensation capacitorsDo not connect power factor compensation capacitors or surge absorbers to thegenerator cables (between the converter and the generator). They are not designedto be used with converters, and will degrade generator control accuracy. They cancause permanent damage to the converter or themselves due to the rapid changesin the converter output voltage.If there are power factor compensation capacitors in parallel with the three phaseinput of the converter, ensure that the capacitors and the converter are not chargedsimultaneously to avoid voltage surges which might damage the unit.Equipment connected to the rotor cableInstallation of safety switches, contactors, connection boxes, etc.To minimize the emission level when safety switches, contactors, connection boxesor similar equipment are installed in the rotor cable (i.e. between the converter andthe rotor):• EU: Install the equipment in a metal enclosure with 360 degrees grounding for theshields of both the incoming and outgoing cables, or in another way connect theshields of the cables together.Bypass connection
