AUXILIARY SUPPLY +24Vdc
Note:
• Always insert a power relay or a thermal magnet on every phase of the products power
supply.
• If a power supply between 380V and 480V is utilized and ground protection is not present, or there
is an asymmetrical grounding system, an isolation transformer is required.
The nominal power of the transformer is calculated by adding the various wattage of each mo-
tor:
Pt = Pn+Pn+Pn+...
Pt= nominal power of the transformer (VA)
Pn= nominal power of each motor (VA), which can be calculated in this way:
Pn = n x Cn / 9,55
Pn=nominal motor power (W)
n= motor speed (rpm)
Cn= motor nominal torque (Nm)
• For single phase power supply use L1 and L2.
