Some Standard Requirements For Electric Security Fences; Definitions; Installation, Operation And Maintenance - JVA Z14 Installation And User Manual

11. SOME STANDARD REQUIREMENTS
The JVA range of energizers has been extensively tested and certified in
accordance with international standards. JVA does not take responsibility for the
erection standards of the fence. It is the responsibility of the erector to consult and
comply with the Standards and Codes of Practice for the installation and erection
of electric security fences. For the user's convenience, we include some Standard
Requirements here but the installer also needs to consult standards such as SABS
1063, 0142, SABS IEC 60335-2-76.

11.1 Definitions

Physical Barrier
A barrier of not less than 1.5m in height and intended to prevent inadvertent contact
of persons with the conductors of the electric fence.
NOTE: Physical barriers are typically constructed from vertical sheeting, rigid
vertical bars, rigid mesh or rods of chain wire mesh.
Public Access Area
Any area where persons are protected from inadvertent contact with pulsed
conductors by a physical barrier (see above).
Pulsed Conductors
Conductors that are subjected to high voltage pulses by the energizer.
Secure Area
An area where a person is not separated by a physical barrier (see above) from
pulsed conductors (see above) below 1.5m.

11.2 Installation, Operation and Maintenance

11.2.1 Electric security fences and their ancillary equipment shall be installed,
operated and maintained in a way that minimises danger to persons, and
reduces the risk of persons receiving an electric shock unless they attempt
to penetrate the physical barrier, or are unauthorised to be in the secure
area.
11.2.2 A space of 2.5m shall be maintained between uninsulated electric fence
conductors or uninsulated connecting leads that are supplied from different
energizers. This space can be less where the conductors or the connecting
leads are covered by insulating sleeving, or consist of insulated cables that
are rated to at least 10kV.
