Connecting the bus coupler as a final station
1. Set up the correct pin assignments (see Table 5 on page 64)
on the plug connections if you do not use pre-assembled
cables.
2. Connect the incoming bus line to one of the two X71/X72
plugs.
3. Close the unused socket with an M12 protective cap to
ensure IP protection (see the chapter "Spare parts and
accessories" on page 84).
4. Connect the shield on both sides of the bus cable directly to
the plug housing (EMC housing), if non-pre-assembled
cables and plugs with metal housing are used. This protects
data lines from terminal interference.
A potential equalization line of at least 10 mm
between the devices to avoid compensating currents from
flowing over the shield of the bus coupler.
The bus coupler cable must at least fulfil the requirements
for category CAT5e and should be a cable with double
shielding (S/STP) with a maximum length of 100 m.
5. Ensure that the plug housing is securely fitted to the bus
coupler housing.
