3.3 Earthing
Please note
·
Connect one of the earth cables of the SFC−DC with low
impedance (short cable with large cross−sectional area)
to the earth potential.
You can thereby avoid faults due to electromagnetic
influences and ensure electromagnetic compatibility in
accordance with EMC guidelines.
To connect the SFC−DC to the earth potential, use
one
of the
following earth connections:
earthing strip at the free end of the power supply cable,
see assembly instructions for cable type
KPWR−MC−1−SUB−15HC−..., or
earth connection on the housing of the SFC−DC,
see Tab.3/3.
Please note
Note that only one of the two earth connections may be
used at the same time (to avoid earth loops).
When using the earth connection on the housing of the
SFC−DC:
·
Use a suitable earthing cable with an M4 cable lug and
the supplied nut with toothed lock washer.
·
Tighten the nut with max. 1.7 Nm.
