4. Connections
This chapter provides information on connecting power and control wiring to the Vacon 50X AC drive.
4.1 General Wiring Information
Pay conscientious attention to ensuring that the installation wiring is installed in conformity with local
standards. Where local codes exceed these requirements, they must be followed.
4.1.1 Wiring Practices
When making power and control connections, observe these precautions:
• Never connect input AC power to the motor output terminals T1/U, T2/V, or T3/W.
Damage to the drive will result.
• Power wiring to the motor must have the maximum possible separation from all
other power wiring. Do not run in the same conduit; this separation reduces the
possibility of coupling electrical noise between circuits.
• Cross conduits at right angles whenever power and control wiring cross.
• Good writing 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.
4.1.2 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 VDE, UL or CUL recognized wire.
2. Wire voltage rating must be a minimum of 300 V for 230 Vac systems and 600 V
(Class 1 wire) for 400 Vac systems.
Danger
HAZARDOUS VOLTAGE
• Read and understand this manual in its entirety before in-
stalling or operating the Vacon 50X AC drive. Installation,
adjustment, repair, and maintenance of these drives must
be performed by qualified personnel.
• Disconnect all power before servicing the drive. WAIT 5
MINUTES until the DC bus capacitors discharge.
• DO NOT short across DC bus capacitors or touch un-
shielded components or terminal strip screw connections
with voltage present.
• Install all covers before applying power or starting and
stopping the drive.
• The user is responsible for conforming to all applicable
code require-ments with respect to grounding all equip-
ment.
• Many parts in this drive, including printed circuit boards,
operate at line voltage. DO NOT TOUCH. Use only electri-
cally-insulated tools.
Before servicing the drive:
• Disconnect all power.
• Place a “DO NOT TURN ON” label on the drive disconnect.
• Lock the disconnect in the open position.
Failure to observe these precautions will cause shock or
burn, resulting in severe personal injury or death.
