V2.20 –English 2/179 1. SAFETY INFORMATION

Technical description

ME382 and MT382

1.2. Safety instructions

1.2.1. Handling and mounting

At the beginning of installation at the metering point, the meter should be carefully taken out of the box

where it was packed. This should prevent the meter from falling as well as any other external or internal

damage to the device and personal injuries. Should such an incident occur despite all precautions the meter

may not be installed at the metering point as such damage may result in different hazards. In such case, the

meter needs to be sent back to the manufacturer for examination and testing.

CAUTION: The edges of the seals, sealing wires as well as some edges under (removed) terminal cover are

sharp!

CAUTION: The temperature of the terminal block of the connected and operating meter may rise, therefore

the temperature of the terminal cover may rise as well.

DANGER: In case of any damage inside the meter (fire, explosion...) do not open the meter.

CAUTION: The meter may be used only for the purpose of measurement for which it was produced.

Any misuse of the meter will lead to potential hazards.

WARNING: Safety measures should be observed at all times. Do not break the seals or open the meter at

any time!

It must be consulted in all cases where symbol is marked in order to find out the nature of the

potential hazards and any actions, which have to be taken to avoid them.

The meter installation procedure is described in the Installation and maintenance manual. For safety reasons

the following instructions should be followed.

See the complete Technical description for detailed technical features of ME382 and MT382 meters

and its intended use.

V2.20 –English 3/179 1. SAFETY INFORMATION

Technical description

ME382 and MT382

Only a properly connected meter can measure correctly! Every connection error could result in a

financial loss for the power company!

1.2.2. Meter installation procedure

DANGER: The ME382/MT382 electricity meter is a device connected into the electricity network. Any

unauthorized manipulation of the device is dangerous for life and prohibited according to the

applicable legislation. Any attempt to damage the seals as well as any unauthorized opening of the

terminal or meter cover is strictly forbidden.

Installation companies shall implement a training policy that ensures that all installers are adequately trained,

understand risk and safety issues and possess the relevant skills before they commence operational duties.

The installer will need to recognise and understand different metering installations, meter types and various

equipment associated with those installations applicable to the successful installation of the electricity meter.

The installer must consult and comply with local regulations and read the installation instructions

written in the Installation and maintenance manual before installation.

The Installation and maintenance manual provides the instructions for installing ME382/MT382 meters.

The document provides a short overview of the meter, details of device installation and set-up, installation

considerations, and health and safety considerations.

The installer will be considered as a public face by both the power company and its customers. The installer

shall adopt the highest standards of behaviour and be respectful to clients and members of the public.

Before the beginning of the installation procedure, check if the metering point is correctly prepared for meter

installation. The metering point must always be left clean and in order.

The work location shall be defined and clearly marked. Adequate working space as well as means of access

and lighting shall be provided at all parts of an electrical installation on, with, or near which any work activity

is to be carried out.

Where necessary, safe access to the work location shall be clearly marked.

The metering point must not be exposed to running water or fire.

Meter installation may not be performed by unauthorised and untrained personnel. Such persons are not

allowed to cut the seals and open the terminal or meter cover as contact with the live parts of the meter is

dangerous for life.

Opening the terminal or meter cover is dangerous for life because there are live parts inside.

Installation personnel must possess the required electrical knowledge and skills, and must be authorised by

the utility to perform the installation procedure.

The installer is obligated to perform the installation procedure in accordance with the national legislation and

internal norms of the utility.

National legislation can set out the minimum age and the competence criteria for installers. In case there are

no national requirements defined, the following criteria shall be used by assessing the competence of

installers: knowledge of electricity, experiences on electrical work, understanding of the installation

V2.20 –English 4/179 1. SAFETY INFORMATION

Technical description

ME382 and MT382

procedures, practical experience of that work, understanding the hazards which can arise during the work

and the precautions to be observed, ability to recognize at all times whether it is safe to continue working.

According to the basic principles, either the nominated person in control of the electrical installation or the

nominated person in control of the work activity shall ensure that specific and detailed instructions are given

to the personnel carrying out the work before starting and on completion of the work.

Before starting work, the nominated person in control of the work activity shall give notification to the

nominated person in control of the electrical installation, of the nature, place and consequences to the

electrical installation of the intended work.

CAUTION: The installer is expected to fully understand the risks and safety issues involved in

electrical installations. The installer shall be aware at all times of the potential hazard of electrical

shock and shall exercise due caution in completing the task!

Tools, equipment and devices shall comply with the requirements of relevant National or International

Standards where these exist. Tools, equipment and devices shall be used in accordance with the

instructions and/or guidance provided by the manufacturer or supplier.

Any tools, equipment and devices provided for the purpose of safe operation of, or work on, with, or near

electrical installations shall be suitable for that use, be maintained and be properly used.

Personnel shall wear clothing suitable for the locations and conditions where they are working. This could

include the use of close-fitting clothing or additional PPE (personal protective equipment).

CAUTION: The installer must be correctly equipped with personal protection equipment (PPE) and

use the appropriate tools at all times during the installation.

Working procedures are divided into three different procedures: dead working, live working, and working in

the vicinity of live parts. All these procedures are based on the use of protective measures against electric

shock and/or the effects of short-circuits and arcing.

The installer must be informed if the national legislation permits the work on the installation under

voltage –live work, and must follow the rules of legislation.

Depending on the kind of work, the personnel working in such conditions shall be instructed or

skilled. Live working requires the use of specific procedures. Instructions shall be given how to

maintain tools, equipment and devices in good working order and how to verify them before working.

This subclause deals with the essential requirements (“the five safety or golden rules”) for ensuring that the

electrical installation at the work location is dead and secure for the duration of the work.

This shall require clear identification of the work location. After the respective electrical installations have

been identified, the following five essential requirements shall be undertaken in the specified order unless

there are essential reasons for doing otherwise: disconnect completely (1.), secure against re-connection

(2.), verify that the installation is dead (3.), carry out earthing and short-circuiting (4.) and provide protection

against adjacent live parts (5.).

V2.20 –English 5/179 1. SAFETY INFORMATION

Technical description

ME382 and MT382

CAUTION: Do not attempt to install the meter before you have isolated the installation site from the

network!

DANGER: The relevant preliminary fuses must be removed before making any modifications to the

installation, and kept safe until completing the work to prevent the unnoticed reinsertion.

DANGER: Secondary circuit of current transformer must not be opened when current is flowing in the

primary circuit. This would produce a dangerous voltage of several thousand volts at the terminals and the

insulation of the transformer would be destroyed.

DANGER: Connecting the meter into the network under voltage is dangerous for life so the conductors at the

metering point must not be connected to any voltage source during the connection procedure. The meter

connection procedure may only be performed by well-trained and adequately authorized personnel.

CAUTION: Only one wire or ferrule may be connected in one terminal. Otherwise, the terminal could be

damaged or the contact could not be made properly.

CAUTION: Use only prescribed types of cables for the installation!

DANGER: The insulation of the connecting cable must extend over the whole visible part of the cable.

There must be no further bare part of the cable visible above the terminal edge. Touching live parts is

dangerous for life. The stripped part of the connecting wire should be shortened if necessary.

CAUTION: At the end of installation at the metering point, no cable should stay unconnected or hanging

freely from the metering point.

The meter has to be mounted on a smooth vertical surface and fixed at 2 or 3 points with screws using the

proper torque (the meter has two attachment holes and, optionally, a top hanger).
