General information
Observe the following information on electrical installation:
• Observe the general safety notes.
• Comply with all instructions referring to the technical data and the permissible con-
ditions where the unit is operated.

Installation instructions
5.2.1
Connecting power supply cables
• The nominal voltage and frequency of the MOVIMOT
®
inverter must correspond to
the data for the power supply system.
• Install safety features F11/F12/F13 for line fuses at the beginning of the power sup-
ply cable behind the supply bus junction, see chapter "Connection of MOVIMOT
®
MM..AVSK".
The following safety features are permitted for F11/F12/F13:
– Fuses in utilization category gG
– Miniature circuit breakers with characteristic B or C
– Motor overload circuit breaker
Size the safety features according to the cable cross section.
• SEW
‑
EURODRIVE recommends using insulation monitors with pulse-code meas-
urement in voltage supply systems with a non-earthed star point (IT systems). Use
of such devices prevents the insulation monitor false tripping due to the earth ca-
pacitance of the inverter.
• Size the cable cross section according to the input current I
mains
for rated power
(see operating instructions, "Technical data" chapter).
