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.
