3. Wire gauge must be selected based on 125% of the continuous input current rating
of the drive. 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 the
460 V 22 kW models require 90 °C wire to meet UL requirements. See Chapter 2 for
the continuous output ratings for the drive.
4. Grounding must be in accordance with VDE, NEC and CEC. If multiple Vacon 50X
drives are installed near each other, each must be connected to ground. A central
earthing point should be used for interference suppression (e.g. equipotential
bonding strip or centrally at an interference suppression filter). The earthing lines
are routed to the respective terminals radially from this point. Conductor loops of
the 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 the
constraints of the conduit entry and bend radius inside the drive.
4.1.3 Considerations for Control Wiring
Control 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 least
600 V for 460 Vac systems.
See Table 5 below for a summary of power terminal control wiring specifications.
