Chapter 2 — WiringBulletin No. 50006-519-01BGeneral Wiring Practices December 1996WIRINGGeneral Wiring PracticesBranch Circuit ConnectionsGood wiring practice requires the separation of control circuit wiring from allpower (line and load) wiring. Power wiring to the motor must have the maximumpossible separation from all other power wiring, whether from the same drive orother drives; do not run in the same conduit. This separation reduces thepossibility of coupling electrical noise between circuits.When wiring ALTIVAR TM 56 drive controllers, follow the wiring practicesrequired by national and local electrical codes in addition to the following:• When metallic conduit is used with ATV56U41N4 to D23N4 andATV56U41M2 to D16M2 drive controllers, a metal conduit entry plate, kitVY1A66201, must be used. It mounts in place of the existing plastic plate andis held in place with two screws. A bond wire is included, which must beconnected to ground (GND) on the J2 terminal strip.• Use metallic conduit for all drive controller wiring. Do not run control andpower wiring in the same conduit.• Metallic conduits carrying power wiring or low-level control wiring must beseparated by at least 3 in (8 cm).• Non-metallic conduits or cable trays used to carry power wiring must beseparated from metallic conduit carrying low-level control wiring by at least12 in (30.5 cm).• Whenever power and control wiring cross, the metallic conduits and nonmetallicconduits or trays must cross at right angles.• In some installations, conducted emissions to the line from the drive controllermust be attenuated to prevent interference with telecommunication, radio andsensitive electronic equipment. In these instances, attenuating filters may berequired. Consult catalog for selection and application of these filters.All branch circuit components and equipment (such as transformers, feeder cables,disconnect devices and protective devices) must be rated for the maximum inputcurrent of the ALTIVAR 56 drive controller, not the motor full load current. Thedrive controller input current is stamped on the nameplate. Since maximum inputcurrent depends on the impedance of the power system, several nameplate valuesare listed. The input current values listed are based on available fault current at thedrive input terminals. Select the input current corresponding to the available faultcurrent capability. If current limiting fuses or circuit breakers are used to reduce theavailable fault current, use the maximum input current listed. On theATV56U41N4 to D79N4 and ATV56U41M2 to D46M2 drive controllers, thenameplate is located in the bottom right corner of the right side of the drivecontroller.WARNINGOVERCURRENT PROTECTIVE DEVICES MUST BE PROPERLY COORDINATED• To achieve published fault withstand current ratings, install the specified fuses listedon drive controller nameplate and in Table 11 on page 30.• Do not connect drive controller to power feeder whose short circuit capacityexceeds drive controller withstand fault rating listed on drive controller nameplate.Failure to follow these instructions can result in death, serious injury, orequipment damage.All ALTIVAR 56 drive controllers require fuse protection. ATV56U41N4 to D79N4and ATV56U41M2 to D46M2 drive controllers require user-supplied external fusesas indicated on the nameplate and in Table 11 on page 30 and Table 13 on page 31.16 © 1996 Square D All Rights Reservedηττπ://νιχοντρολσ.χοm
