WARNINGS
Internal Electronic Circuits
Parts of the internal electronic circuits of these meters are, due to technical necessity, connected to
PHASE VOLTAGES.
Dangerous voltages are present
A Terminal Cover Plate must always be fitted to the A1120/40 meter to protect the main meter
terminals. If the Terminal Cover Plate is not fitted to the A1120/40 meter, all supplies to the meter
must be isolated before a module, module peripheral equipment or external battery module is installed
or removed.
Failure to do so may result in electric shock.
Caution
Installation of a faulty module or module peripheral equipment may affect the main meter functionality.
Removal of the main cover invalidates the certification of certified meters.
Liquid Crystal Display
Liquid crystals are toxic. If a display is damaged, avoid contact with the liquid. If the liquid makes
contact with the skin it must be washed off immediately with water.
Seek medical advice.
Batteries
The meter contains an internal Lithium manganese dioxide primary cell. This battery is completely safe
under normal conditions. However, it must never be recharged, disassembled, heated above 100° C,
incinerated, or have the contents exposed to water.
Fire, explosion or severe burns may result if these instructions are disregarded.
In the interests of safety, environmental protection and possible legislation, Lithium batteries require
careful disposal. Before arranging for the disposal of these cells, users should satisfy themselves that
the proposed means of disposal is both safe and compliant with local legislation requirements.
Elster Metering Systems would like to draw the user's attention to the International Standard for
Lithium Batteries - IEC 60084-4 - which gives further information about the handling, storage, transport
and disposal of lithium cells.
Elster Metering Systems should be contacted by the user should difficulties arise in arranging proper
disposal. They will if practical help the user identify safe disposal means.
An optional External Battery Module supports the display and optical communications during power
outages. A non-rechargeable "alkaline" (alkaline zinc manganese dioxide) PP3 (IEC 6LR61) battery is
used.
This battery is completely safe under normal conditions. It must not be recharged, disassembled,
short-circuited, overheated or incinerated. It contains corrosive materials.
Used batteries should be disposed of in compliance with local legislation requirements.
