3.2. Mains supply
The PSU series is designed for fixed connection to TN networks (TN-C, TN-C-S or TN-S).
Please note that the line-earth voltage may not exceed 300VAC.
•
When grounding the neutral conductor, mains voltages
of up to 480VAC are permitted.
•
When grounding an external conductor (delta mains,
two-phase mains), mains voltages (external conductor
voltages) of up to 300VAC are permitted.
Servo controllers which are to be connected to an IT network must be provided with a
separating transformer. Then the PSU device is operated locally like in a TN network. The
secondary sided center of the separating transformer must be grounded and connected to the
PE connector of the PSU.
4.Parameters set-up
N.B.: This operation must be executed only by the first axis connected to the PSU.
4.1.1. Voltage supply
The default status of the drive is configured to 400VAC (=560V DC). For all other cases, it’s
necessary to set the correct value of the voltage [3-phase VAC
supply

230V AC 3-phase Æ Pr206 = 325

To activate the new configuration, it’s necessary to save the parameter and restart the PSU
unit.
