14Power ConnectionsMake all power connections with 75o C rated copper wiring.Conduit entry must be from the bottom on all drives. Conduit entries areprovided on smaller drives. For drives with auxiliary enclosures, referto the dimensional drawings provided for conduit entry locations.To meet UL requirements, install the metal grounding plate in all drivesthat have a plastic bottom. Install the grounding plate just above theplastic bottom. Ground the metal plate to the chassis and ground theconduit to the metal plate.The conduit entries provide strain relief for the wires in drives mountedin NEMA 1 or NEMA 12 enclosures. With chassis mounted drives, thepower and control wires must have strain relief supplied by the installer.DO NOT rely on the terminal blocks to provide strain relief.Input Power ConnectionFor drives with no auxiliary enclosure, connect input power to driveterminals L1, L2, and L3, (terminal numbers 91, 92, and 93). If an auxiliaryenclosure is provided, input power connections are made in the auxiliaryenclosure. Refer to the connection diagrams shipped with the drive.Size wiring to the input current of the drive as shown in the tablesbelow. Maximum AWG wire size is also provided.Enclosures for larger drives and auxiliary en-closures are made of metal. To avoid gettingmetal chips into electronics, do not drill anyholes after unit has been installed in a verticalposition. 460 VAC Input Current/Wire Gage208 VAC Input Current/Wire GageAll current ratings are in amps.Drive InputCurrentMaximumAWG Model2.5 10 H2.12.5 10 H3.03.4 10 H3.44.8 10 H4.88.3 10 H8.210.6 10 H1114 10 H1421 6 H2127.6 6 H2734 6 H3441 6 H4053 2 H5264 2 H6577 2 H77103 1/0 H106145 2/0 H130174 3/0 H160206 2x1/0 H190256 2x1/0 H240317 2x3/0 H302366 2x4/0 H361443 3x1/0 H443540 3x3/0 H540590 3x3/0 H590678 3x4/0 H678Connecting input power to motor terminals willresult in drive failure when power is applied.Motor Wiring ConnectionFor drives with no auxiliary enclosure, connect the motor to driveterminals U, V, and W (terminal numbers 96, 97, and 98). Terminal 99is earth ground. If an auxiliary enclosure is provided, refer to theconnection diagrams shipped with the drive. Ground the shield on themotor wire, if used, at both the drive and the motor.GroundingGround the drive properly. Use a ground wire at least 7 AWG (10mm2 ).Connect the ground wire directly to a reliable earth ground. Do not usethe conduit connecting to the drive as a replacement for a ground wire. Donot ground one drive to another in a “daisy chain” fashion.Electronic Thermal ProtectionThe electronic thermal relay is UL approved for single motor thermalprotection as long as the following is complied with:1. Parameter 117, Thermal Protection, is set to ETR TRIP.2. Parameter 105, Motor Current, is set for the full-load nameplatemotor current.CAUTION!DANGER!For operator safety, it is important to grounddrive properly.WARNING!575 VAC Input Current/Wire GageDrive InputCurrentMaximumAWG Model5.0 10 C4.66.0 10 C6.67.0 10 C7.510.0 10 C1116.0 10 C1723.0 6 C2430.0 6 C3146.0 6 C4659.2 2 C5974.8 2 C7588.0 0 C88101.3 1/0 C114126.6 3/0 C143149.9 4/0 C169Drive InputCurrentMaximumAW G Model2.5 6 J2.73.0 6 J3.96.0 6 J6.19.0 6 J9.010.0 6 J1116.7 6 J1721.6 6 J2226.6 6 J2731.5 6 J3240.3 2 J4151.2 2 J5261.0 0 J62
