POTENTIAL EQUALIZATION
There is a risk of electrical interference when the ground potential between the servo system and the machine is different.
-
Install equalizing cables between them. The recommended cable cross-section is 16 mm
EMC INTERFERENCE
Use shielded cables for control wiring and separate cables for power and control wiring. Failure to isolate power and
-
control wiring can result in unintended behavior or reduced performance.
Ensure a minimum clearance of 200 mm between signal and power cables.
-
Only cross cables at 90°.

5.4 Mains Supply Requirements

Ensure that the supply has the following properties:
• TN-S, TN-C, TN-CS, TT (not corner earthed) supply earthing system.
• Prospective short-circuit current: 5 kA.
• Protective class I.
• Grounded 3-phase mains network, 400–480 V AC ±10%.
• 3-phase lines and PE line.
• 3-phase frequency: 44–66 Hz
• Maximum input current for 1 PSM 510 at 30 kW: 55 A

5.4.1 Fuses

Use fuses on the supply side of the Power Supply Module PSM 510 that comply with CE and UL requirements (see
-
When 2 PSM 510 modules are used, each PSM 510 must have its own dedicated set of fuses.
