All Premise Owners: Commercials or Industrial

PURPOSEThis booklet is intended to enforce the method of installing the electric fence

in order to improve the safety level of the installation according to MS IEC

60335-2-76 standard. This booklet is also to inform of the procedures that

must be complied with by the applicant in order to obtain approval from the

Energy Commission on the installation of electric fence.

BACKGROUND

Previously the Energy Commission had issued a directive and a circular

pertaining to the needs and method of installing the electric fence. In line

with the current technology, the existing directive and previous circular of

installing the electric fence need to be revised. Therefore, a conducive and

comprehensive method of installing the electric fence concurrent to the

international standards needs to be prepared.

Generally the installation of electric fence installed by some parties is toprevent their properties from being trespassed by intruders either animal or

human. The types of premises involved in the installation of electric fence are

those that involve activities related to agriculture and security control such

as military, power utility, water and others. Therefore, these installations of

electric fence need to be installed in a control manner and safe in accordance

to the Electricity Supply Act 1990, Electricity Regulations 1994 and other

relevant standards so as to prevent the occurrence of on the part of the

intruder/trespasser.

COMPLIANCE WITH LEGISLATION

The proper and safe method of installing the electric fence shall begin

from the stage of design until the stages of construction, supervision,

maintenance and monitoring. It needs to be implemented in accordance

with the requirements of the Electricity Regulations 1994. The respective

regulations that need to be complied with are as follows:-

Regulation 15 : Requirement of any conductor for the purpose

of connection to an installation which shall be constructed, installed,

arranged, protected, worked and maintained shall be sufficient in size,

power and number as to prevent danger.

Regulation 65 : Requirement of competent persons (Part VI of the

Second Schedule) who shall prepare and submit plans, drawings and

specifications for voltage/ampere limit of an installation.

Regulation 68 : Requirement to appoint competent person either an

Electrical Services Engineer, Competent Electrical Engineer or Electrical

Supervisor to inspect the electric fence installation.

Regulation 75 : Requirement to appoint a registered electrical

contractor with Energy Commission which hold a valid Certificate of

Registration to perform or carry out the installation of electric fence.

Regulation 110 : Electric fence installation shall be maintained in

good, working order and safety precautions shall be observed at all times

to prevent danger.

Regulation 111 : Requirement to appoint a competent person or

a person acting under the control of a competent person who shall

undertake to carry out any repair, replacement, servicing or cleaning of

the installation.

METHODS OF ELECTRIC FENCE INSTALLATION

To ensure the installation of electric fence is continuously carried out in a

proper and safe manner, the Energy Commission has provided the method of

installing the electric fence which complies with standard of MS IEC 60335-

2-76 Particular requirements for electric fence energizers.

(Note: MS IEC 60335-2-76 standard can be purchased from SIRIM Berhad)

Some of the main priorities that need to be emphasized during the construction

stage of electric fence either of energizer type A, B, C, or D are as stated in

the clauses and Annexes of MS IEC 60335-2-76 standard as follows:-

i. Clause 22.108 - Energizer output characteristics shall be such that

- the impulse repetition rate shall not exceed 1 Hz

- the impulse duration of the impulse in the 500 component of the

standard load shall not exceed 10 ms

- for energy limited energizers the energy/impulse in the 500

component of the standard load shall not exceed 5 Joule(J)

Figure 1 : Measurement of voltage value at electric fence (pulse conductor) beingdone using Voltmeter.

ii. Clause 22.109 -If the energizer is provided with more than one fence

circuit (sometimes it defines zone), the output characteristics shall

be within limits in 22.108 for any possible connection of the fence

circuits. The impulses for the individual sets of output terminals shall

be synchronized .

Figure 2 : The use of panel for synchronizing supply system if more than one

energizer applies.

Figure 3 : Area which is supplied by more than one different sources of energizershas been synchronized for supply to the electric fence.

iii. Annex BB Instructions for installation and connection of electric

fences.

Annex BB1 & BB2 Requirements for electric animal/securityfences:-

- Any electric animal/security fence shall not be supplied from two

separate energizers or from independent fence circuits of the same

energizer.

- For any two separate electric animal/security fences, each supplied

from a separate energizer independently timed, the distances between

the wires of the two electric animal/security fences shall be at least

2.0/2.5 m. If this gap is to be closed, this shall be effected by means

of electrically non-conductive material or an isolated metal barrier.

Figure 5 : Earthing system for the installation of electric fence

Figure 6 : Distance of physical barrier shall be at least 2.0 / 2.5 meters if

receives two supplies from different energizers and both suppliesnot synchronised. (Note: 2.0 m for animal while 2.5 m for security)

Figure 4 : Lightning protection system and component used

iv. Annex CC Installation of electric security fences

Annex CC.2 Location of electric security fence

- The electric fence should be separated from the public access area

by means of a physical barrier.

- Where an electric fence is installed in an elevated position, such as on

the inner side of a window or skylight, the physical barrier may be less

than 1.5 m high where it covers the whole of the electric fences. If the

bottom of the window or skylight is within a distance of 1.5 mfrom the

floor or access level then the physical barrier need only extend up to

a height of 1.5 m above the floor or access level.

(Note: Refer to figures 7, 8 & 9 for examples of physical barrier)

REMINDER!

A Competent Electrical Engineer must ensure the installation of electric

fence under his responsibility is installed in compliance with the standard of

MS IEC 60335-2-76.

(Note: The latest version of the standard MS IEC 60335-2-76 needs to be referred to from

time to time).
