4.4 Network configuration: cables, hubs, switches - Recommendations
Cables and connectors comply with the POWERLINK specifications. Cables are
CAT-5 shielded cables.
Standard POWERLINK cables commercially available can be used.
For complete information please refer to IEC 61918, IEC 61784-5-13 and IEC
61076-2-101.
To increase noise immunity only S/FTP or SF/FTP cables must be used (CAT-5).
The maximum cable length (100 meters) predefined by Ethernet 100Base-TX
must be compulsorily fulfilled.
EPL recommends the use of hubs to fit POWERLINK jitter requirements.
Switches may be used to build a POWERLINK network.
It has to be considered that any POWERLINK network constructed with anything
but Class 2 Repeater Devices does not conform to the POWERLINK standard.
Regarding wiring and EMC measures, the IEC 61918 and IEC 61784-5-13 must
be considered.
For a complete list of the available cordsets and connection kits please refer to
the product datasheet (“Accessories” list).
4.5 Ground connection
To minimize noise connect properly the shield and/or the connector housing
and/or the frame to ground. Connect properly the cable shield to ground on
user's side. Lika's EC- pre-assembled cables are fitted with shield connection to
the connector ring nut in order to allow grounding through the body of the
device. Lika's E- connectors have a plastic gland, thus grounding is not possible.
If metal connectors are used, connect the cable shield properly as recommended
by the manufacturer. Anyway make sure that ground is not affected by noise. It
is recommended to provide the ground connection as close as possible to the
device. We suggest using the ground point provided in the cap (see Figure 2, use
1 TCEI M3 x 6 cylindrical head screw with 2 tooth lock washers).
4.6 Connection of the shield
Disentangle and shorten the shielding
1
and then bend it over the part
2
; finally
place the ring nut
3
of the connector. Be sure that the shielding
1
is in tight
contact with the ring nut
