UL STANDARDS ON CABLINGTo obey the UL (Underwriters Laboratories)regulations, use a UL-approved Class 1copper wire with a minimum heatresistance of +158 or +167 °F (+70 or +75°C).You can use the drive on a circuit that givesa maximum of 50 000 rms symmetricalamperes, and a maximum of 500 V AC,when the drive is protected by Class T andJ fuses.CABLE AND FUSE SIZES,NORTH AMERICAThe recommended fuse types are classT (UL & CSA). The fuse voltage ratingshould be selected according to the supplynetwork. The final selection should bemade according to local regulations,cable installation conditions and cablespecifications. Bigger fuses than thoserecommended below shall not be used.Check that the fuse operating time is lessthan 0.4 seconds. Operating time dependson used fuse type and impedance of thesupply circuit. Consult the factory aboutfaster fuses. VACON® also recommendsfor high speed J (UL & CSA) fuse ranges.THE TECHNICAL DATA OF THE VACON® 20 X AC DRIVEVACON® 20 X AC DRIVESINSTALLATIONIN US AND CANADADownload and read VACON® 20 X Installation Manual,wall-mounted drives at:http://drives.danfoss.com/knowledge-center/technical-documentation/The dimensions of the cables must agreewith the requirements of the UL508C.• The cables must be PVC-isolated.• The maximum ambient temperatureis +104 °F (+40°C).• The maximum temperature of thecable surface is +158 or +167 °F(+70 or +75°C).• Use only cables with a concentriccopper shield.• The maximum number of parallelcables is 9.When you use parallel cables, make surethat you obey the requirements of thecross-sectional area and the maximumnumber of cables.For important information on therequirements of the grounding conductor,see the UL508C.For the correction factors for eachtemperature, see the instructions of theUL508C.QUICK GUIDEDPD01821BTechnical item or function Technical dataMainsconnectionInput voltage Uin3AC 208…240V1AC 208...240V3AC 380...480VInput voltage tolerance -15%…+10% continuouslyInput frequency 50/60 HzInput frequency tolerance 45…66 HzProtection class IConnection to mains Once per minute or lessStarting delay 4 sSupply networkIT and TN-networks(cannot be used with corner earthednetworks)Short-circuit current Maximum short-circuit currenthas to be <50kADC connection Available as standard inMU2 single-phase frames and MU3MotorconnectionOutput voltage 3AC 0…UinRated output current IN: Ambient temperature max. +40°COverload output current 1.5 x IN (1 min/10 min)Starting current IS for 2 s every 20 s (IS = 2.0 * IN)Output frequency 0…320 HzFrequency resolution 0.01 HzProtection class IMotor characteristics AC squirrel cage motorsPermanent magnet motorsCable type Screened motor cableCable maximum length 30 mControlcharacteristicsSwitching frequencyProgrammable 2…16 kHz;Default 6 kHz.Automatic switching frequencyderating in case of overheatingFrequency reference:Analogue inputPanel referenceResolution ±0.05% (11-bit),accuracy ±1% Resolution 0.01 HzField weakening point 8…320 HzAcceleration time 0.1…3000 secDeceleration time 0.1…3000 secBraking Brake chopper standard in all three-phaseframes.
