Exercise caution when applying the Vacon 500x AC drive on low-line conditions.
For example, an Vacon 500x 2000 series unit will operate properly on a 208 Vac line, but the maximum
output voltage will be limited to 208 Vac. If a motor rated for 230 Vac line voltage is controlled by this drive,
higher motor currents and increased heating will result.
Therefore, ensure that the voltage rating of the motor matches the applied line voltage.
4.3.2 Line Capacity
If the source of AC power to the Vacon 500x AC drive is greater than 10 times the kVA rating shown in Table
3 below, an isolation transformer or line reactor is recommended. Consult the factory for assistance in
sizing the reactor.
Note: Vacon 500x AC drive devices are suitable for use on a circuit capable of delivering not more than
65,000 rms symmetrical amperes at 10% above the maximum rated voltage.
4.3.3 Phase Imbalance
Phase voltage imbalance of the input AC source can cause unbalanced currents and excessive heat in the
drive’s input rectifier diodes and DC bus capacitors. Phase imbalance can also damage motors running
directly across the line. The phase imbalance should not exceed 2% of the voltage rating; if it does, the
drive should be derated as a single-phase drive.
4.3.4 Single-phase Operation
Vacon 500x AC drive 230 Vac, 4-kW/5-HP models are designed for both three-phase and single-phase input
power. If one of these models is operated with single-phase power, use any two line input terminals. The
output of the device will always be three-phase.
The safe derating of the Vacon 500x series of drives is 50% of the nominal current (kW/HP) rating. Consult
the factory with the particular application details for exact derating by model.
4.3.5 Ground Fault Circuit Interrupters (GFCI)
The GFCI breakers are designed for residential use to protect personnel from stray currents to ground.
Most GFCI breakers will shut off at 5 mA of leakage. It is not uncommon for an AC drive to have 30 to 60
mA of leakage.

CAUTION
ATTENTION
EQUIPMENT DAMAGE HAZARD
Never use power-factor correction capacitors on motor terminals T1/U, T2/V, or T3/W of the
Vacon 500x AC drive. Doing so will damage the semiconductors.
Failure to follow this instruction can result in injury or equipment damage.
RISQUE DE DOMMAGES MATÉRIELS
Ne raccordez jamais de condensateurs de correction du facteur de puissance aux bornes T1/
U, T2/V, ou T3/W du moteur du variateur de vitesse Vacon 500x. Car cela endommagera les
semiconducteurs.
Si cette directive n’est pas respectée, cela peut entraîner des blessures corporelles ou des
dommages matériels.
