2.3. End-of-life disposal
SL7000 meters comply with the requirements of WEEE regulations for recycling or reuse of materials.
At the end of their service life, meters should be uninstalled and then passed to a licenced/certified contractor for
disposal in accordance with these regulations and with all applicable local regulations.
Before passing the meters to the contractor the legal certification stamps or marks must be removed or defaced.

11
Meters must be installed and maintained only by suitably-qualified personnel. Observe the following safety advice
when performing installation or service work on meters.
Meter handling
Before installing or removing a meter, or removing the terminal cover for any reason, isolate the
meter from the mains supply by removing the supply-side fuses or using alternative local
arrangements. Take appropriate measures to ensure that the isolation cannot be overridden by
another person. For example, keep physical possession of the supply fuses.
•Adhere strictly to all relevant national regulations for the avoidance of electrical accidents.
•Always disconnect all measurement and auxiliary circuit connections from the meter before
attempting to open the meter housing.
•Use only tools that have been approved for electrical installations.
•Clean meters only with a damp cloth or sponge. Do not use excessive or running water.
Installation
Install meters in accordance with the voltage and current specifications printed on the front panel and
the wire and environmental specifications given in the installation information.
•The meter measuring and auxiliary circuits must be galvanically isolated.
•All voltage paths (measurement and auxiliary) must be fused.
•The meter voltage connections must be physically separated from the communication lines in
accordance with local laws and regulations.
•Do not install meters that are obviously damaged.
•Do not install meters that have been dropped or otherwise subjected to significant impact even if
no damage can be seen.
•Do not HIPOT/Dielectric test the auxiliary or communication circuit connections.
•Do not use any meter functions or features for primary protection purposes.
•Do not install meters where failure of the device could cause death, injury or release sufficient
energy to start a fire.
•Following installation, ensure that the meter terminal covers are correctly fitted and sealed to
prevent user access.
Transformer connections
Observe all industry guidelines and safety precautions when performing any installation or service
work on meters connected to Voltage (VT) and/or Current Transformers (CT).
Contact with transformer connections while current is flowing in the primary will result in severe
personal injury or death.
Transformers that do not have a ground connection on the secondary may reach dangerously high
output voltages.
•Always isolate voltage transformers by removing their fuses.
•Always short-out current transformer secondary circuits.
•Always ensure the transformer secondary circuit is connected to ground unless a special wiring
arrangement is required.
•Always exercise extreme caution when handling transformer connections, especially if the
transformer secondary does not have a ground connection.

4.3. Meter support tools
The SL7000 meters have an extensive range of optional facilities and settings, enabling them to be configured to
suit individual requirements. In general, a meter is fully configured and programmed for its intended application
prior to despatch from the factory.
However, some aspects of the configuration may be changed at any time using dedicated Windows™-based
support tools that typically communicate via the optical port on the front of the meter.
Support tool applications provide the following main features:
•metering point management
•configuration creation and editing
•configuration programming and reading
•meter data reading
•meter firmware upgrading
The following support tool is currently available:
