3.3 Earthing
Note
· Connect one of the earth terminals of the SFC−LACI at
low impedance (short cable with large cross−section) to
the earth potential.
You can thereby avoid interference from electromagnetic
sources and ensure electromagnetic compatibility in
accordance with EMC directives.
To earth the SFC−LACI, use one of the following terminals
(seeĂTab. 3/3):
ć Earth terminal on the housing of the SFC−LACI, or
ć Earthing strip with cable lug on the plug housing.
Note
Note that
only one of the three earth terminals may be
used (to avoid earth loops).
When using the earth terminal on the housing of the
SFC−LACI:
· Use a suitable earthing cable with an M4 cable lug
together with the accompanying nut and toothed washer.
· Tighten the nut with max. 1.7 Nm.
