Agreed Product Use

The intended and non-intended use of iTraMS CCU product is discussed in the below sections.

Intended Use

RBEI will be responsible for delivered products being fit for use of purpose intended and/or having a defined level of quality, such responsibilities are subject to the application of the product conforming to the agreed upon environment, installation and stress conditions, as such are referenced in the attached specification.

When the product during the Bosch release procedures has successfully met the testing specifications agreed to the Customer, it is deemed to fully cover all requirements, if any, that the product be fit for the use or purpose intended and/or have a defined level of quality. Customer shall be responsible for the system application, which includes ensuring that the intended product application and all environmental, installation and stress conditions to which the product will be exposed are covered by such testing. Customer shall be responsible for making sure that the product will not be exposed to conditions in excess of those referenced in such testing specifications. The conditions of use (environment, application, installation and loads) contained in this manual and associated agreed documents constitute the scope of the product’s suitability for its contractually required, intended or ordinary use and the scope of the product’s condition/ quality. The customer is responsible for ensuring the product’s usability in the vehicle.

The product is intended for and is undergoing approval for installation and operation in automobiles, commercial vehicles, off-highway vehicles and coaches with a rated voltage of 12(24) volts. It may be necessary to adapt the product’s factory-set state to suit the specific country.

Only connecting cables and external devices that are appropriate for the device in question as regards safety, electromagnetic compatibility and grade of shielding may be used. Compliance with the applicable standards cannot be guaranteed if the device is modified without the agreement of Bosch.

Bosch is only responsible for implementing the device side connector (interface) according to the customer’s specifications. Bosch does not assume any responsibility and does not provide any guarantee for the plug-in connection ­ in particular for its electrical functioning, durability and imperviousness ­ since this is applied by request of the customer.

If, in order to connect the device, ignition and battery are bridged, the device will draw the full operating current even when switched off. In this case, without any further deactivation on the vehicle-side, there is a risk of battery depletion. No liability is assumed for any damage occurring because of this. Do not cover ventilation openings and heat sinks ­ otherwise a build-up of heat may occur in the device that could lead to malfunction. There are no specific ventilation openings or heat sinks in CCU device, but mounting in a thermal capsuled environment should be avoided, as it will lead to an increase of the operating temperature.

Do not insert foreign bodies in the insertion slots or openings of the device ­ otherwise injury or damage to the device may occur.

The device must not be exposed to hot or burning objects (e.g. cigarettes).

To clean the device, never use hard or sharp objects that could damage the protective pane or housing. Do not use aggressive cleaning agents such as thinners, benzene, abrasive cleaners, spray cleaners, acidic or alkaline solutions, or wax. Do not spray any liquids onto the device. To clean the housing moisten a soft cloth with tepid water and wipe off the dirt. Make sure that no liquid enters the inside of the housing. Afterwards, wipe the cleaned surface with a clean, dry cloth.

If the device is to be cleaned before installation in the vehicle, make sure the openings (in particular the connector contact points) are kept sealed so that no liquid can enter the device.

Annexure

Abbreviations Used

EMC Recommendations

• Do not route the sensitive signals in parallel to high tension wires (ignition, Digital I/O).
• Wire from CCU to Vehicle battery should be as short as possible.
• Avoid loops in the routing.
• CCU ground shall be as short as possible fixed to chassis or directly to battery ground
• For CAN wiring, it is recommended to use a twisted pair (Figure 3).

Wiring

• If necessary, wires of type FLR (R = reduced thickness of insulation) must be used.
• It is recommended to use constantly insulator copper strands as per DIN 72551 or the newer automotive norms LV112.
• Mechanically unloaded cables can also be connected as wires with reduced thickness of insulation (FLX or FLKr wiring).
• As per DIN 40621, the cables should be laid in a cable protection sleeve.
• Wiring harness layout in the vehicle – Sharp edges in the wiring layout should be avoided. The wiring and primarily the plug connections must be protected against direct water or spray mist.

Pin-Out details

The different connectors and their pin-out details are discussed in the below sections

BAY1: HSAL Connector
BAY2: Main Connector
BAY3: RF Connector

Best Practice for Wiring Routing

• Due to the effects of gravity passing water through the wires, the CCU should be packaged higher than any wire end or splice in the harness.
• Measures should be taken to prevent water from collecting around the wiring harness. Plastic wire covering/protection should allow water to drain from harness.
• Wiring should be routed away from water drainage areas. Wires that are routed around sharp edges or that can be damaged from stone impingements should be protected.
• Water in the wiring harness can cause interference on various signal wires due to poor wiring insulation.
• Wires splices and ground eyelets must be located away from direct contact with high pressure cleaner.
• Any wire end terminating in a splash water area should be orientated so that the wire end is pointing down.
