2 Safety and maintenance information

2.1

Responsibilities

The owner of the meter is responsible to assure that all authorized persons who work with
the meter read and understand the relevant sections of the User manual that explains the
installation, maintenance and safe handling with the meter.
The installation personnel must possess the required electrical knowledge and skills, and
must be authorised by the utility to perform the installation procedure.
The personnel must strictly follow the safety regulations and operating instructions, written in
the individual chapters of the User Manual.
The owner of the meter responds specially for the protection of the persons, for prevention of
material damage and for training of personnel.
MetCom Solutions provides training courses related to the above mentioned items.
2.2

Safety instructions

The following safety regulations must be observed:
• The conductors to which the meter will be connected must not be under voltage during
installation or change of the meter. Contact with live parts is dangerous to life. The
relevant preliminary fuses should therefore be removed and kept in a safe place until
the work is completed, so that other persons cannot replace them unnoticed.
• Local safety regulations must be observed. Installation of the meters must be
performed exclusively by technically qualified and suitably trained personnel.
• Secondary circuits of current transformers must be short-circuited (at the test terminal
block) without fail before opening. The high voltage produced by the interrupted current
transformer is dangerous to life and destroys the transformer.
• Transformers in medium or high voltage Solutions must be earthed on one side or at
the neutral point on the secondary side. Otherwise they can be statically charged to a
voltage which exceeds the insulation strength of the meter and is also dangerous to
life.
• Meters which have fallen must not be installed, even if no damage is apparent. They
must be returned for testing to the service and repair department responsible (or the
manufacturer). Internal damage can result in functional disorders or short-circuits.
• The meter must on no account be cleaned with running water or with high pressure
devices. Water penetrating can cause short-circuits.
