NOTICE
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
2
.
NOTICE
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

•
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
•

5.4.1 Fuses
NOTICE
-
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.
