Connection with Festo CAN bus plug
Note
· Use protective caps or blanking plugs to seal unused
connections.
You will then comply with protection class IP65/IP67.
· Note the fitting instructions for the CAN bus plug. Tighten
the two fastening screws at first by hand and then with
max. 0.4 Nm.
You can connect the CPX−CEC−C1 easily to the CAN bus
with the CAN bus plug from Festo,
type FBS−SUB−9−BU−2x5POL−B. You can disconnect
the plug from the node without interrupting
the bus line
(T−Tap function).
Note
The clamp strap in the Festo CAN bus plug is connected
only capacitively internally with the metal housing of the
sub−D socket. This prevents equalising currents from
flowing via the screening of the CAN bus line (Fig.2/4).
· Clamp the screening of the CAN bus line under the clamp
strap in the CAN bus plug.
