Wire gauge must be selected from wire tables for 75 °C insulation rat-ing, and must be of copper construction. The 230 V 5.5 and 11 kW models, and the460 V 22 kW models require 90 °C wire to meet UL requirements. See Chapter 2 forthe continuous output ratings for the drive.4. Grounding must be in accordance with VDE, NEC and CEC. If multiple Vacon 50Xdrives are installed near each other, each must be connected to ground. A centralearthing point should be used for interference suppression (e.g. equipotentialbonding strip or centrally at an interference suppression filter). The earthing linesare routed to the respective terminals radially from this point. Conductor loops ofthe earthing lines are impermissible and can lead to unnecessary interference.See Table 4 below for a summary of power terminal wiring specifications.NOTE: Wire type not specified by the manufacturer. Some types of wire may not fit within theconstraints of the conduit entry and bend radius inside the drive.4.1.3 Considerations for Control WiringControl wiring refers to the wires connected to the control terminal strip. Select control wiring as follows:1. Shielded wire is recommended to prevent electrical noise interference from caus-ing improper operation or nuisance tripping.2. Use only VDE, UL or CUL recognized wire.3. Wire voltage rating must be at least 300 V for 230 Vac systems. It must be at least600 V for 460 Vac systems.See Table 5 below for a summary of power terminal control wiring specifications.Vacon 50X Size /Models SpecificationsSize 01.36 Nm (12 in-lbs) nominal torque or1.47 Nm (13 in-lbs) maximum torque1.5–4 mm 2 (11–15 awg wire)Size 11.8 Nm (16 in-lbs) nominal torque or2.0 Nm (18 in-lbs) maximum torque1.5–10 mm 2 (7–15 awg wire)Size 2 3.4 Nm (30 in-lbs) nominal torque10–16 mm 2 (5–7 awg wire)Size 3 4.0 Nm (35 in-lbs) nominal torque25 mm 2 (3 awg wire)Size 4 7.3 Nm (64 in-lbs) nominal torque25 mm 2 (3 awg wire max)Size 5 14.9 Nm (131 in-lbs) nominal torque120 mm 2 (250MCM wire max)Table 4:Vacon 50X Power Terminal Wiring SpecificationsVacon 50X Size / Models SpecificationsAll Sizes / Models 0.5 Nm (4.4 in-lbs) maximum torque0.2–4 mm 2 (12–24 awg wire)Table 5:Vacon 50X Control Wiring Specifications
