9.7.6 Network set up
Data transfer cable
For setting up the MATRIX.Net use only data transfer cable certified according to DIN
19245 T3 and EN 50170 with twisted pair cores and braided shield.
Line length
Regadless of the cross section and the number of participants the maximum line length
including stub lines to the control panel may amount to a maximum of 600 m.
The stub line may not exceed 25 m. The total length of all stub lines may not exceed a
maximum 150 m.
The cross-section of the bus cable must be changed depending on the MATRIX.net
cable length!
Shielding / Earthing
•
Install the data transfer cable (MATRIX.Net)
on one side
in the unit using shielding
clips to ensure the best possible electrical contact
•
Connect the shielding with the shielding clip to a large earth surface area!
•
In systems with a large network extent, or if large scale EMC impairment is likely,
the shielding should be applied on both sides. Before this operation make sure that
no potential differentials occur.
RECOMMENDATION
We recommend the following data transfer cable:
Producer: HELUKABEL
Type: CAN-BUS flexible 2 x 2 x ... mm²
RECOMMENDATION
Repeaters must be used in the network if there are more than 110 users and
the cable length is long. To increase the line length, special jumpers are neces-
sary to decouple running times of telegrams between the netwokr participants
