• Good wiring practice also requires separation of control circuit wiring from all power wiring.
Since power delivered from the drive contains high frequencies which may cause interference
with other equipment, do not run control wires in the same conduit or raceway with power or
motor wiring.
4.2.2 Considerations for Power Wiring
Power wiring refers to the line and load connections made to terminals L1/R, L2/S, L3/T, and T1/U, T2/V,
T3/W respectively. Select power wiring as follows:
1. Use only UL-recognized wire.
2. Wire voltage rating must be a minimum of 300 V for 230 Vac systems and 600 V (Class 1 wire) for 460 or
575 Vac systems.
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 rating, and must be of copper construction.
The 230 V 5.5 kW/7.5 HP and 11 kW/15 HP models, and the 460 V 22 kW/30 HP 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 NEC and CEC. If multiple Vacon 500x drives are installed near each
other, each must be connected to ground. Take care not to form a ground loop.
See Table 1 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.
4.2.3 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 causing improper operation
or nuisance tripping.
2. Use only UL 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 systems.
See Table 2 below for a summary of power terminal control wiring specifications.
4.3 Input Line Requirements
4.3.1 Line Voltage
See “Power and Current Ratings” on page 14 for the allowable fluctuation of AC line voltage for your
particular Vacon 500x model. A supply voltage above or below the limits given in the table will cause the
drive to trip with either an overvoltage or undervoltage fault.
