Ethernet switch EC2095
7
►
Lay supply and Ethernet cables away from the device using the shortest possi-
ble route.
►
All connected cables must be provided with a strain relief.
5.2 Operating voltage
The supply voltage can be connected to V1 or V2 as option. 2 different
sources have to be connected for redundant operation, however.
Core cross-section: 0.3...1.3 mm.
Cable length for optimum performance: ≤ 10 m
►
To protect the device use fuses for the operating voltages.
Description
Potential
M12 connector (5 poles)
Fuse
Operating voltage V1
10…30 V DC (V1)
Pin 1
max. 2 A T
Operating voltage V2
10…30 V DC (V2)
Pin 4
max. 2 A T
The operating voltage is electrically separated from the functional earth.
5.3 Ground connection
►
To ensure the protection of the device against electrical interference, the hou-
sing must be connected to GND (e.g. to the ground of the vehicle).
►
For permanent installation in a vehicle connect the ground via an M5 fixing
screw.
Core cross-section: ≥ 0.5 mm²
►
Ensure a well-conductive connection.
5.4 Ethernet
►
Use a shielded CAT5 cable.
STP, Shielded Twisted Pair, according to EIA/TIA-568.
Max. length 100 m
►
Use screened connector housings and connect the screen of the Ethernet
cable to the connector housing.
►
Do not lay the Ethernet cable in parallel to live cables.
5.5 Assignment of the ports
Ports 1 ... 5 can be used by the devices as required.
(→ 3 Intended use, application examples)
Connection from one port to another port on the same Ethernet switch is
prohibited. It will cause a failure of the network (broadcast storm).
