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.

2.3 Maintenance
No maintenance is required during the meter’s life-time. The implemented metering
technique, built-in components and manufacturing procedures ensure high long-term stability
of meters. Therefore, no recalibration is required during entire meters life-time.
•In case the service of the meter is needed, the requirements from the meter installation
procedure must be observed and followed.
•Cleaning of the meter is allowed only with a soft dry cloth. Cleaning is forbidden in the
region of terminal cover, where cables are connected to the meter. Cleaning can be
performed only by the personnel responsible for meter maintenance.
CAUTION: Never clean soiled meters under running water or with high pressure
devices. Penetrating water can cause short circuits. A damp cleaning cloth is sufficient
to remove normal dirt such as dust.
•The quality of seals and the state of the terminals and connecting cables must be
regularly checked.
DANGER: Breaking the seals and removing the terminal cover or meter cover will lead
to potential hazards because there are live electrical parts inside.
•After the end of the meter’s lifetime, the meter should be treated according to the
Waste Electric and Electronic (WEEE) Directive!
2.4 Disposal
The components used in the MCS301 are largely recyclable according to the requirements of
the environmental management standard ISO14001. Specialized disposal and recycling
companies are responsible for material separation, disposal and recycling. The following
table identifies the components and their treatment at the end of the life cycle.
Components
Waste collection and disposal
Circuit boards Electronic waste disposal according to local regulations
LED’s, LCD Special waste: Dispose of according to local regulations.
Metal parts Recyclable material: Collect separately in metal containers.
Plastic parts To be recycle separately. If necessary, Of waste incineration.
Batteries
Prior to disposal of unused or used Li-Batteries, safety precautions
must be taken against short circuits. Batteries can leak or ignite.
Do not dispose of used or defective lithium batteries in the household
waste but observe the local waste and environmental regulations.

3 Basic functionality
The basic functionality of the meter is described below:
•High accuracy
Digital measured data processing with a digital signal processor (DSP) and high
sample rate for accurate, flexible measured-value processing the energy and
demand in all 4 quadrants. Additionally, Power Quality data are provided
•Configuration
User-friendly readout and configuration tool Blue
2
Link, enabling users to define their
own different function variants.
•Load profile for billing and power quality purpose
Providing an extended load profile functionality all billing data as well as the Power
quality data, like voltage, current, harmonics and THD can be stored over a longer
time period and can be readout by the connected HES system.
•Anti-Tampering features
The meter supports a lot of Anti tampering features like
•terminal and main cover detection
•communication module removal detection
•magnetic field detection
•Communication modules for AMI application
The MCS301 meter is prepared for AMI application by using communication
modules (GSM / GPRS / LTE, Ethernet …), which can be exchanged in the field.
•Power supply
The meter's power supply is available for 2 different application
•Transformer rated power supply for dedicated nominal voltage level, like
3x220/380V–3x240/415V or 3x58/100V-3x63/110V
•Wide range power supply working from 3x58/100V – 3x277/480V
i.e. if two phases fail, or one phase and the neutral, the meter will remain fully
functional. If phase and neutral conductor will be connected in a wrong way the
meter displays an alarm. All meter types of the MCS301 are earth fault protected; in
that case the meter can handle a voltage of 1.9Un for more than 12h.
•Readout during power outage (only with external battery support)
The behavior during power outage is described below.
•After pressing the alternate button the LCD will be switched ON.
oAll data can be displayed on the LCD.
oAll data can be readout through the optical interface.
•The LCD will be switched OFF after the following events:
oWithout pressing the push button within 10s.
oAt reaching the end of the data readout list
•Auxiliary power supply
The CT meter can be supported with an auxiliary power supply from 48 – 230V
AC/DC. In case the auxiliary power supply is connected, the meter is powered from
the aux.power supply, otherwise the meter power supply is used
