ATTENTION:
1)
, strictly follow safety rules of car repair
works as well as local safety rules of the customer
’
company.
2)
Before starting DUT-E S7 Radiobox RS connection operations, study carefully the
electric equipment diagram and the operation documentation of the
to be equipped.
It is required to conduct DUT-E S7 Radiobox RS exterior inspection for the presence of the
possible defects arisen during transportation, storage or careless use. Contact the product
supplier if there any defects.
IMPORTANT:
DUT-E S7 Radiobox RS should not be mounted near heating and
cooling devices (e.g. the climate control system). Also, it is not recommended to
mount DUT-E S7 Radiobox RS close to the vehicle electrical circuits.
You need to make sure that there are no sources of electromagnetic interference near
mounting place (radio telephones, video signal transmission units and other wireless
devices operating within 2.4 or 5.0 GHz frequency bands.
DUT-E S7 Radiobox RS installation should be done in a dry location protected from aggressive
impact of the environment. A suitable location to mount DUT-E S7 Radiobox RS is inside
driver’s cabin
.
For uninterrupted data transmission in conditions of the Vehicle, it is recommended that the
distance between DUT-E S7 Radiobox RS and DUT-E S7 sensors should not exceed 20 m.
To fix DUT-E S7 Radiobox RS, make use of the self-adhesive clasps that are contained in the
DUT-E S7 Radiobox RS is powered from the external source (e.g. Vehicle onboard circuit). The
power supply, service and output interfaces of DUT-E S7 Radiobox RS are to be connected, in
accordance with the designation of wires of
OUT
wire bundle
(see table 8 and
figure 29).
IMPORTANT:
1)
Before mounting and connecting DUT-E S7 Radiobox RS switch off power supply
of the Vehicle electrical circuits. To do this switch off the battery switch or release
the terminals of the wires connected to the battery. To eliminate the electric
equipment damaging, the accumulator battery is allowed to be switched on only
after the completion of the electric equipment connection.
2)
Prior to electrical connection of the sensor pay special attention to checking
chassis ground. Resistance between any point of vehicle chassis and
“
-
” terminal of the battery or between terminals of the chassis ground switch
should not exceed 1 Ohm.
3)
When connecting DUT-E S7 Radiobox RS to onboard electrical network of Vehicle,
use fuse (2 A) from delivery set in accordance to scheme of connection.
We recommend to purchase and use connectors for connecting
OUT
wire bundle to the
respective wires of the Vehicle onboard circuit.
DUT-E S7 Radiobox RS starts operating from the moment the power supply is ON;
it is switched off, as soon as the power supply (onboard circuit) is OFF.
