1 Notes and safety instructions
1.1 General notes
Please read and take note of these WARNING, Caution and
Note descriptions before carrying out maintenance or repair
work.
Caution
Text with this symbol indicates the risk of damage to your
vehicle.
Note
Text with this symbol contains additional information.
The pages that follow contain all of the information (subject
to technical changes) required to retrofit the “Alpine SPC-400TT"
system. This description corresponds to the status of
the Workshop Manual at the time of going to press.
The “Alpine SPC-400TT” system must be installed by a
qualified workshop. Special tools, testing devices and vehicle-specific literature will be needed to perform the installation. Improper installation can cause damage to the vehicle
or the “Alpine SPC-400TT” system.
Alpine will not accept responsibility in the event of
failure to comply with these installation instructions.
1.2 General safety instructions for pyro-
technical, electrical and mechanical
components of the restraint system
Pyrotechnical components comprise:
Airbag units
Belt tensioners
Seatbelt load limiter (depending on fixtures)
Battery disconnecting elements (depending on fixtures)
In general:
Testing, installation and maintenance tasks must only be
carried out by trained personnel.
Do not check using circuit tester, voltmeter, or ohmmeter under any circumstances.
1
Page 4
Before handling pyrotechnical components of the restraint
system (e.g. before disconnecting the electrical connector),
the person carrying out the task must “discharge any static
electricity”. This can be done by briefly touching the door
latch, for example.
The power supply to the system must always be disconnected when working on the pyrotechnical components of the
restraint system.
Disconnect the battery when the ignition is switched off
The battery negative terminal must subsequently be covered.
No waiting time is necessary after the battery has been disconnected.
Observe the measures that apply after disconnecting the
battery
Pyrotechnical components must neither be opened nor repaired. Strictly use new parts only.
Pyrotechnic components that have fallen onto a hard surface
or that show any sign of damage must not be installed.
Pyrotechnical components of the restraint system must be
installed immediately after they have been taken out of the
transport container.
If work is put on hold, place the pyrotechnic components
back into the transport container.
It is not permissible to leave pyrotechnical components of
the restraint system sitting unsupervised.
“Wash hands” after touching ignited pyrotechnical components of the restraint system.
When connecting pyrotechnical components of the restraint
system, only the person performing the work may be present
inside the vehicle.
Storage and transportation are subject to the applicable national laws.
Pyrotechnical components must not be treated with grease,
cleaners, or similar agents.
In addition, pyrotechnical components must not be exposed
to temperatures above 100 °C, even on a temporary basis.
