Safety

1.1 Safety information
The following symbols are used to draw your attention to the relevant danger level, i.e. the severity and probability of any danger, in the individual sections of this document.
Danger
This symbol is used to indicate a possibly dangerous situation that could result in severe physical injury or death.
Warning
This symbol is used to indicate a possibly dangerous situation that could result in minor physical injury or material damage.

Note
This symbol is used to indicate general details and other useful information.
In addition to the danger level, safety information also describes the type and source of the danger, its possible consequences, and measures for avoiding the danger.

1.2 Meter Operator Code of Practice
The E470 must be installed in accordance with the Meter Operation Code of Practice Agreement (MOCOPA®), defining safety, technical and business interface requirements regarding the provision of meter operation services.
For more information see www.mocopa.org.uk

1.3 Safety regulations
The following safety regulations must be observed at all times:

• Local safety regulations must be observed and shall take precedence over these regulations in the event of a conflict. Only technically qualified and appropriately trained personnel are authorized to install the meters.
• Meters that have been dropped must not be installed, even if no damage is apparent, but must be returned to the service and repair department (or the manufacturer) for testing. Internal damage may result in malfunctions or short-circuits.
• The meters must not be cleaned under running water or with compressed air. Water ingress can cause short-circuits.
• The meter terminal cover should be secured in place before any load is supplied.

Physical description

2.1 Meter construction
This document doesn’t include a description of the internal construction of the meter. Opening the meter after delivery isn’t permitted. If it is opened the meter’s calibration and certification will automatically be rendered void.
The meter case is made of antistatic polycarbonate plastic glass filled 10%.
The top part of the meter houses an intimate communications hub interface (ICHI).
The middle part of the meter – the meter faceplate area – comprises the user interface with the liquid crystal display (LCD), the metrology (measurement) light-emitting diode
(LED) and the display buttons A and B.
The lower part of the meter – the terminal area – is protected by a removable terminal cover. It includes the main electricity ingress and egress terminals and auxiliary connections.
