Security Classification Unrestricted Version - Siemens ST950 Handbook

To isolate the equipment, the Master Switch must be in the "Off"
position.
Removal of the Electricity Board Fuse or Switching the Controller switch or the Manual
Panel Signals On/Off switch to "Off" does not guarantee isolation of the equipment.
Controller Configuration
Controllers require specific configuration to enable them to function correctly when
installed.
The configuration process is a complex activity and should only be carried out by
persons who are adequately trained, have a full understanding of the needs of the
county or region were the controller is to be used and are experienced in the tasks to
be undertaken.
Safety of Road Users
It is important that all personnel are aware of the dangers to road users that could arise
during repair and maintenance of traffic control equipment.
Ensure that the junction area is coned and signed as necessary to warn motorists and
pedestrians of any dangers and to help protect the personnel working on the site.
Whilst repairing signals which are in an "all-out" condition, care must be taken to
ensure that no spurious signals are lit during testing which could mislead drivers or
pedestrians. Particular care is required where pedestrian audible devices are installed,
to ensure that no false indications are given during, for example, cable testing.
Personnel should also ensure the safety of pedestrians, especially children, who may
come into contact with parts of the controller or signal poles.
Safety Warning - Lithium Battery
This equipment may contain a Lithium coin cell (battery) if the optional RTC battery
backup kit is installed.
Do not short circuit, recharge, puncture, take apart, incinerate, crush, immerse, force
discharge, ingest or expose to temperatures above the declared operating temperature
range of the product, otherwise there is a risk of fire or explosion.
Batteries should be handled and stored carefully to avoid short circuits. Do not store in
disorderly fashion, or allow metal objects to be mixed with stored batteries. Keep
batteries between -30°C and 35°C for prolonged storage.
The battery is a sealed unit which is not hazardous when used according to these
recommendations. Do not breathe vapours or touch any internal material with bare
hands should the cell become damaged in any way.
Battery disposal method should be in accordance with local, state and government
regulations. In many countries, batteries should not be disposed of into ordinary
household waste. They must be recycled properly to protect the environment and to cut
down on the waste of precious resources.
