13. Mounting, installation rules
13.1. Mounting instructions
Router can be mounted in any position. To ensure proper cooling and access to
router we recommend to keep a free space of minimum 70 mm sidewise and
100 mm from the upper surface of the radiator. Alternatively, cooling can be
arranged by additional means (fans, another measures). Free space of at least
10 cm must be left on the side of the connectors for cable connection and
fastening.
It is very important to ensure that ambient temperature does not exceed the
allowed limits. Moreover, it is necessary to ensure that heat radiation equipment
located nearby does not cause exceeding of temperature limits.
Due to its weight, router must be mounted on sufficiently dimensioned wall of
vehicle body. Sufficient dimensioning of fixtures/brackets and screws is also
needed.
13.2. Cabling
PE terminal of power supply connector must be connected with local installation
earthing terminal.
Minimum cross-section of supplying conductors must be at least 0.75 mm
2
.
The cables or individual wires being connected to the device must be protected
against mechanical stress. Cables or individual wires must be protected against
mechanical stress by binding to solid installation parts. Length of cable or
individual wire between last binding point and the control unit connector should
not exceed 15 cm.
Ethernet line connection must be carried out using shielded cables of category
CAT. 6 and higher.
Data communications and I/O signals interconnections must be done with
shielded cables. Shielding must be connected either to metal connector caps or
to router PE terminal.
All PE connections must be realized with as low as possible impedance.
