Installation instructions
5.1.1
Supply system connection
• The rated voltage and frequency of the MOVIMOT
®
inverter must correspond to the
data for the power supply system.
• Install line fuses at the beginning of the power supply cable behind the supply bus
junction, see F11/F12/F13 in chapter "Connection of MOVIMOT
®
drive".
Use only D, D0 or NH fuses, or circuit breakers for F11/F12/F13. Select the fuse size
according to the cable cross section.
• SEW-EURODRIVE recommends using earth-leakage monitors with pulse code
measuring in voltage supply systems with a non-grounded star point (IT systems).
The use of such devices prevents the earth-leakage monitor mis-tripping due to the
earth capacitance of the inverter.
• Cable cross section: according to input current I
line
for rated power (see chapter
"Technical Data" in the operating instructions).
