1. Introduction
Only trained personnel authorised by the customer and/or FREQUENTIS
may handle the system.
Always read this manual carefully before starting to install or service the
system.
For easy access, keep the Safety Guidelines at hand on site.
1.1. Purpose
These Safety Guidelines explain the precautions and basic information required
for correct handling of a system from the range of released products of
FREQUENTIS (e.g. VCS 3020 Series, VCX, DICORA). For details of the actual
configuration, please refer to the System Configuration document.
These Safety Guidelines are concerned with workplace and equipment safety not
including the reliability of the system.
1.2. Target Group
The Safety Guidelines contain precautions to be taken by the trained installation
and/or maintenance staff when servicing the system. They are intended for
everyone involved in preparing for the infrastructure, installing the system and/or
maintaining its components. Moreover, this manual is aimed at anyone who deals
physically with the system.
The staff is expected to be aware of obvious hazards. Furthermore, they have to
be appropriately trained for and experienced enough to recognise hazards in
their daily work, and to minimise risks to themselves and others.
The staff must be trained and observe, among others, appropriate ESD-practices
and procedures for handling the cabinets, boards and cabling. A FREQUENTIS
training course covering the technical part (basics and maintenance) of the
system is essential to achieve the correct handling of the system.
1.3. Requirements Concerning Warranty
Only trained personnel authorised by the customer and/or FREQUENTIS may
prepare the site, install, put into operation and maintain the system.
All warnings and instructions contained in the applicable documents supplied
must be observed. The meaning of the warning symbols used is described in
chapter 1.4. Major warnings e.g. concerning risks of injuries or damage to the
equipment are listed in chapter 1.6.
Violation or non-observance of the Safety Guidelines in this document cancels or
restricts the warranty provided by FREQUENTIS. In particular, FREQUENTIS
shall not be responsible for any resultant operational errors or any damages
caused to persons, properties or whatsoever.

2. Safety Instructions
Above all, basic prerequisites must be considered concerning safety instructions,
protection against electrostatic discharge, overvoltage caused by electrical
transients or lightning, electromagnetic compatibility, infrastructure planning, site
survey and area identification.
This section covers the safety-critical service phases: personal safety, fire
hazards, electrical shocks, injuries, handling safety and equipment safety.
2.1. Safety-Critical Phases of Installation and Maintenance
Only a fully trained technical crew may service the system as the crewmembers
may be exposed to potential hazards of various types while performing their
duties. These hazards must be eliminated or reduced to ensure that the staff is at
minimum risk.
All installation personnel shall be briefed on the potential hazards involved in
installing the system. Awareness of these hazards shall be promoted by the site
safety officer (person responsible for safety at the site), who shall be present
during all safety-critical phases of installation:
1) Unloading of equipment on site
2) Transport of equipment to final location
3) Installation of heavy system parts
4) Initial power application to fully-installed system
5) Changing of boards
The service life cycle consists of the following phases:
1) (Trans)shipment to site
2) Unloading on-site
3) Transport to final location
4) Erection and mechanical assembly at the final location
5) Cabling at the final location
6) Initial equipment power-up
7) Test and integration of fully powered system
8) Adding, changing or removing components
Each of these phases contains some or all of the hazards identified in the
following chapters. Detailed countermeasures are described for each type of
hazard.
The staff have to be aware of the typical hazards already identified and the action
required. The list is in no way conclusive and unforeseen hazards may occur at
any time. Each crewmember is responsible for identifying further hazards and
reporting them to the site safety officer.

No: 00A46 E500.12 Author: S. Meisel COPYRIGHT FREQUENTIS 2000
2.2. Personal Safety
It is of utmost importance not to expose the personnel to unnecessary risks
during their work. Where essential activities involve a safety risk of any kind, the
site safety officer has to be informed. The site safety officer has to take measures
to provide adequate precautions against the hazard, such as fire extinguishers or
medical supervision. The following hazards are predictable:
● Fire hazard Chapter 2.2.1
● Electrical shock Chapter 2.2.2
● Injuries (e.g. tripping over cables or cuts from sharp objects) Chapter 2.2.3
2.2.1. Fire Hazard
Fire hazards can never be totally eliminated, but preventive measures should
ensure that any damage or injury is avoided.
● In particular, the correct type of fire extinguisher always has to be available in
the vicinity of current activities. The personnel shall be instructed by the
person responsible for site safety on the correct use of an extinguisher in an
emergency, the various types and their physical location.
● Burns and/or inhalation of fumes caused by fire must be reported immediately
for treatment by the medical staff.
● Smoking in the facility during the service period is not permitted.
To reduce the risk of fire, use only No. 26 AWG (>0.4 mm ∅) or larger wires
for telecommunication lines.
2.2.2. Electric Shock
Despite the care taken by skilled personnel at work, exposure to electric shock
due to unpredictable events can, however, never be excluded. Line driving and
ringing voltage are health hazards to the personnel. They therefore have to work
with special care during and after the initial power-up, particularly at the
backplanes of the core and interface racks.
Though the following safety precautions should prevent such potential hazards,
the power may be turned on inadvertently by third parties or electrical power may
already be available in other parts of the system.
● Each system component must be correctly connected to ground to minimise
personnel exposure to shock hazards. This must be completed before power of
any voltage is applied. The facility power engineer must ensure that all
grounding points are properly connected to the central bonding rail (the
building’s earth).
● Service activities after connection of the system to the main facility power shall
be co-ordinated by means of mobile communication between the
crewmembers and the facility power engineer, who is responsible for ensuring
that power application at a particular location does not affect other locations.
SAFETY GUIDELINES FREQUENTIS File: SGL REV.1.2.DOC 8
COPYRIGHT FREQUENTIS 2000 Author: S. Meisel No: 00A46 E500.12
● Medical supervision should be provided, but first-aid counter-measurements
will provide the most effective treatment for electrical shock victims. Artificial
respiration is the prime recognised means of resuscitating an electrical shock
victim. All crewmembers must be trained in this method.
● A victim must be separated from live power contacts before resuscitation
measures are employed. If the source of power cannot be accessed or turned
off, a dry, insulated object, such as a broom, must be used to minimise the
risk that the person providing aid is not similarly exposed to the same hazard.
● Qualified medical attention must be sought in all cases of electrical shock
exposure to ensure that no symptoms remain. The site safety officer must be
immediately informed of an accident to notify the appropriate authorities.
● Provision must be made in the grounding system to protect the personnel
from live circuitry due to carelessness or equipment failure. A survey must be
performed of the available voltage sources that could be encountered at the
equipment area to provide adequate protection from electrical hazards.
The equipment may have more than one power supply cord! To avoid
electric shock, disconnect all power supplies before servicing the system.
2.2.2.1. Causes and Prevention of Electric Shock
Causes of Electric Shock Prevention
Contact with parts normally
at hazardous voltage.
Prevent access to parts at hazardous voltage
by fixed or locked covers, interlocks, etc.
Discharge capacitors at hazardous voltages.
Breakdown of insulation between
parts normally at hazardous
voltage and accessible conductive
parts.
● Connect the accessible conductive parts to
earth to limit the voltage to safe values and
the circuit breaker will disconnect the parts
having low impedance faults.
● Use double or reinforced insulation between
accessible conductive parts and parts which
are at hazardous voltages in normal use.
Breakdown of insulation between
parts at hazardous voltages,
applying it to accessible parts.
Segregate hazardous voltage circuits.
Separate by earthed metal screens or
reinforced insulation. Earth any circuits capable
of carrying fault currents.
Breakdown of insulation guarding
parts at hazardous voltage.
Insulation for parts at hazardous voltage accessible to the authorised representative must
have adequate mechanical/electrical strength
Leakage current from parts at
hazardous voltage to the casing.
Failure of PE-connection.
Limit leakage current to body to a safe value,
or provide high integrity protective earth
connection.

2.2.2.2. Inspection to Prevent Electric Shock
Check, that
1) Protective devices comply with the site-specific requirements in accordance
with the (inter)national regulations.
• Protective earthing (PE) and equipotential bonding conductors meet the
required minimum cross-sections.
• PE- and neutral(N)-conductors are marked suitably and unmistakably.
• PE-conductors contain no switches, fuses or circuit breakers.
• Protective contacts of all plug-and-socket connections work efficiently.
• PE or neutral connection and disconnect points are identified.
2) Cross-sections of cords and cabling are appropriate to current consumption
at maximum load.
3) Connections are made in accordance with to the regulations.
4) Disconnect devices are implemented and suitably placed.
5) Inspection of the appliances shows no obvious lapse from safety provisions.
• All appliances meet the site specific environmental conditions and safety
requirements.
• All appliances are easily accessible for operation and maintenance.
• Warning labels for multiple supplies and/or multiple disconnection are
applied according to the respective appliances.
6) Personnel must be prevented from accessing
• bare parts normally operating at ELV or hazardous voltages and
• operational or basic insulation of such parts or wiring.
7) Generally, between an unearthed accessible conductive part and a primary
circuit double or reinforced insulation must be applied.
8) Conductive handles or their shafts, which are manually moved and earthed
only through a pivot or bearing must be separated from hazardous voltages
• by creepage distances and clearances of double or reinforced insulation,
• by supplementary insulation over accessible parts.
9) Insulation of internal wiring at hazardous voltages accessible to personnel
must not be
• subject to damage or stress,
• needed to be handled in normal operation routines,
• routed or fixed in such a way that unearthed metal parts are touchable.
10) Conductive parts of the equipment exposed to hazardous voltage in the event
of a single insulation fault must be reliably connected to a PE-terminal
resistant to significant corrosion.
11) Fire enclosures and fire prevention sheets are applied according to the
regulations.
12) Documentation for installation and maintenance is available at site.
