Safety Instructions
IV Planning and Installation - Rev. 0 / 04.2002
CAUTION!
Opening the mainframe door or the panel desk may give access to live parts.
In such cases, the unit has to be disconnected completely from the mains.
CAUTION!
This equipment has more than one power supply cord. To reduce the risk of
electric shock disconnect two power supply cords before servicing.
If, however, working on the opened mainframe or opened panel is inevitable, this
has only to be done by qualified service personnel being informed about the dan-
gers involved.
Attention! Capacitors may still carry a residual charge!
If, for example, due to a failure, safe operation of the switcher is no longer ensured,
put the switcher out of operation and secure it against further use.
Do not insert or remove plug-in cards during operation.
Make sure that no parts protrude into the air conditioning holes. This might lead to
contact with dangerous voltages or to damages of sensitive circuit parts.
To prevent damages in the control panel gear no drinks in top of the desk. Pene-
trated liquids can lead to destroying the control panel boards. Make sure that no
small parts (e.g. office parenthesis) fall into the opening under the levers. This can
lead to short-circuits and damages.
The EMC regulations are only applicable when correctly shielded cables are used
for the installation of the equipment. This applies to video cables as well as control
cables. Corresponding cables can be obtained from Thomson.
Run all connection cables in covered cable ducts (risk of stumbling).
For main connection, only use the supplied connection cable or a checked cable of
the same type (three wire cord with earthed protective conductor).
The controller boards of the mainframe and panel contains a lithium battery, which
has to be exchanged every five years. The backup battery in the PC motherboard
has to be exchanged every three years. Perform the exchange of the motherboard
battery during operation to save the CMOS setup data.
Detailed information you can find in the section
Exchange of the lithium battery in
the service manual.
Used batteries must be disposed of carefully to avoid environmental damage.
Caution!
Danger of explosion if battery is incorrectly replaced.
Replace only with the
same or equivalent type recommended by the manufactuerer. Dispose of
used batteries according to the manufacturer’s instructions.
