5.3 Installation instructions
5.3.1 Permitted voltage systems
Information on voltage systems Information on permissibility
TN and TT systems – voltage sys-
tems with directly grounded star point
Use is possible without restrictions.
IT systems – voltage systems with
non-grounded star point
Use is only permitted with electronics cover in
IT system design (...-513-....).
For use in IT systems, SEW‑EURODRIVE
recommends using insulation monitors
with pulse-code measurement. Using
such devices prevents false tripping of the
insulation monitor due to the earth capa-
citance of the inverter.
No EMC limits are specified for interfer-
ence emission in IT systems. The EMC
limits for interference emission specified
in chapter "Technical data" do not apply to
IT system designs.
Voltage systems with grounded
outer conductor
Not permitted.
5.3.2 Connecting supply system cables
The nominal voltage and frequency of the device must correspond with the data of
the supply system.
Dimension the cable cross section according to the input current I
line
for nominal
power (see chapter "Technical data and dimension sheets").
Install safety equipment F11/F12/F13 for line fuses at the beginning of the power
supply cable behind the supply bus junction, see chapter "Connection diagram".
Dimension the safety features according to the cable cross section.
Use only copper conductors with a minimum temperature range of 90°C as con-
nection cable.
