·
Observe the fitting instructions for the field bus plug.
Tighten the two fastening screws at first by hand and then
with max. 0.4 Nm.
Note
The clamp strap in the field bus plug from Festo is
connected internally only capacitively with the metallic
housing of the Sub−D plug. This is to prevent equalizing
currents flowing through the screening of the field bus
cable.
·
Clamp the screening of the field bus cable under the
clamp strap in the field bus plug. The SLD" terminal in
the field bus plug is optional.
