ST950S Plus+ Installation and Commissioning Manual

Safety Information

CAUTION:

General Hazard

IT IS RECOMMENDED THAT DUE TO THE MAINS PRESENT WITHIN THE CONTROLLER

CABINET ALL POWER TO THE CABINET IS DISCONNECTED BEFORE REMOVING OR

INSTALLING ANY MAINS POWERED EQUIPMENT INTO THE CABINET. WHERE A RISK

ASSESSMENT AND METHOD STATEMENT FOR THE WORKS TO BE COMPLETED AND /

OR THE INSTRUCTIONS FOR THE EQUIPMENT BEING INSTALLED OR REMOVED

ALLOWS, LIVE WORKING MAY BE CONSIDERED.

CAUTION:

Safety of Installation and Maintenance Personnel

In the interests of health and safety, when installing, using or servicing this equipment the

following instructions must be noted and adhered to:

1. Only skilled or instructed personnel, with relevant technical knowledge and experience,

who are also familiar with the safety procedures required when dealing with modern

electrical/electronic equipment, are to be allowed to use and/or work on this equipment.

All work shall be performed in accordance with the local regulations1.

2. Such personnel must take heed of all relevant notes, cautions and warnings in this

Handbook and any other Document or Handbook associated with the equipment

including, but not restricted to, the following:

a. The equipment must be correctly connected to the specified incoming power

supply.

b. Only trained / competent persons should work on this equipment.

c. Any power tools must be regularly inspected and tested.

d. Any personnel working on site must wear the appropriate protective clothing, e.g.

reflective vests, etc.

1. For UK this refers to Electricity at Work Regulations 1989.

iii

CAUTION:

Re-Commissioning the Installation

When re-commissioning signals, the following sequence is recommended to ensure that the

correct signal start-up sequence is followed:

•Switch OFF the controller at the main switch

•Switch ON the lamps at the Manual Panel on/off switch

•Switch ON the controller at the main switch

More specific safety information is given in the text of the handbook, where it relates to specific

activities or situations.

CAUTION:

RJ45 Connections

There are various RJ45 connectors used to connect to peripheral cards within the ST950

family of controllers. Most are not Ethernet ports and should not be connected to other

equipment, including PCs.

CAUTION:

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.

CAUTION:

Equipment Compatability

Do not connect any device that has not been specifically designed or evaluated for

compatibility with the ST950S Plus+

system. If in doubt, contact Siemens Mobility Limited for

further information.

ST950S Plus+

compatible equipment such as Helios Plus+

traffic signals, near-side pedestrian

signals and Plus+

LED regulatory signs are all clearly marked “Plus+”. If equipment is not

marked “Plus+” then additional care should be taken to ensure that it is suitable for use in a

Plus+

system.

DANGER:

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 appropriate traffic management and is signed at the junction area 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.

DANGER:

Safety of 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.

DANGER:

Important Plus+

Considerations

To provide the most reliable operation, the Siemens ST950S Plus+

controllers use a DC supply.

To maintain all street voltages within ELV limits, equipment outside the cabinet must

be supplied with voltages within the band 0 to +48V DC with respect to earth. Voltages

beyond that will result in overall voltages within the system being in excess of the ELV

limit as defined by BS7671.

Care should be taken to ensure that no LV (Mains Voltage) equipment is installed within the

ST950S Plus+ street furniture as this will result in risks to personnel and risk of catastrophic

failure of equipment.

The Siemens ST950S Plus+

controller has been designed and proven to meet the following

requirements for Protective Extra Low Voltage (PELV) and the operation of a signal compliance

monitoring system with ELV voltages:

1) The Siemens ST950S Plus+

system is PELV and the earth is connected all the way through,

as allowed for in BS7671 414.4.1. The source is a safety isolating PSU as allowed in BS7671

414.3 (iv). Protective Isolation within the controller cabinet is achieved between the PELV

circuits and those higher than band I by ALL conductors having insulation rated for the highest

voltage 250V, as mandated for in BS7671 414.4.2 (iii), and where the parts of the circuits are

not wires / conductors, then physical isolation as allowed for in BS7671 414.4.2 (v) may be

used.

Important:

Disposal

As with all modern equipment, there are a number of security artefacts that exist within the

hardware. When replacing equipment, the swapped-out CIC and Nodes must be disposed of in

a secure way.
