The EQ meter product is designed to be connected and to communicate
information and data via a network interface, which should be connected to an
internal secure network. It is the users sole responsibility to provide and
continuously ensure a secure connection between the product and the users
network or any other network (as the case may be) and to establish and maintain
appropriate measures (such as but not limited to the installation of firewalls,
application of authentication measures, encryption of data, installation of
antivirus programs, etc.) to protect the EQ meter product, the network, its
system and interfaces against any kind of security breaches, unauthorized
access, interference, intrusion, leakage and/or theft of data or information. ABB
Ltd and its affiliates are not liable for damages and/or losses related to such
security breaches, unauthorized access, interference, intrusion, leakage and/or
theft of data or information.
Although ABB provides functionality testing on the products and software
updates that we release, you should institute your own testing program for any
product updates or other major system updates (to include but not limited to
code changes, configuration file changes, third party software updates or
patches, hardware change out, etc.) to ensure that the security measures that you
have implemented have not been compromised and system functionality in your
environment is as expected.
For maximum security the EQ meter should be installed and sealed in a secure
environment to prevent any unauthorized access. All cables and sealing must be
checked on a regular basis, if any sealing is broken the security and safety can
no longer be ensured and ABB Ltd and its affiliates are not liable for damages
and/or losses related to such disturbances, security breaches, unauthorized
access, interference, intrusion, leakage and/or theft of data or information.

2.1 Mounting the Meter
General
This section describes different ways to mount the A43/A44 meters. For some
methods of mounting additional accessories are needed. For further information
about accessories, refer to the Main Catalog (2CMC480001C0201).
DIN-rail mounted
The A43/A44 meters are intended to be mounted on a DIN-rail (DIN 50022). If
this method of mounting is used no extra accessories are needed and the meter is
fastened by snapping the DIN-rail lock onto the rail.
DIN-rail
The following picture shows a DIN-rail.
Wall mounted The recommended way to mount the meter on a wall is to mount a separate DIN-
rail on the wall and then mount the meter on the rail.

2.3 Installing the Meter
Warning –Electrical equipment should only be installed, accessed, serviced
and maintained by qualified electrical personnel.
Working with high voltage is potentially lethal. Persons subjected to high voltage
may suffer cardiac arrest, burn injuries, or other severe injuries. To avoid such
injuries, make sure to disconnect the power supply before you start the installation.
Warning –For safety reasons it is recommended that the equipment is installed in a
way that makes it impossible to reach or touch the terminal blocks by accident.
The best way to make a safe installation is to install the unit in an enclosure. Further,
access to the equipment should be limited through use of lock and key, controlled by
qualified electrical personnel.
Warning –The meters must always be protected by fuses on the incoming side.
In order to allow for maintenance of transformer rated meters, it is recommended that
there should be a short circuiting device installed near the meter. Alternatively a CT with
short circuiting terminals is used to short circuiting the secondary current during
maintenance. The reason for short circuit the secondary current during maintenance is
that a very high voltage will be induced across the terminals if current is flowing through
the CT primary and any secondary terminal is disconnected. This high voltage can be
potentially lethal and can damage the CT or other equipment.
Cable type Cable type connected to the voltage/current terminals shall be solid or stranded copper
cable. When using stranded cable end ferrules can be used.
Install the meter Follow the steps in the table below to install and verify the installation of the
meter:
Step
Action
1
Switch off the mains power.
2
Place the meter on the DIN-rail and make sure it snaps onto it.
3
Strip the cable insulation to the length that is indicated on the meter.
4
Connect the cables according to the wiring diagram that is printed on the meter
and tighten the screws (3.0 Nm for direct connected meters and 1.5 Nm for
transformer connected meters).
5
Install the circuit protection. See table 2:1 below for the correct fuse.
6
If inputs/outputs are used, connect the cables according to the wiring diagram
that is printed on the meter and tighten the screws (0.25 Nm). Then connect to
an external power supply (max 240V).
7
If communication is used, connect the cables according to the wiring diagram
that is printed on the meter and tighten the screws (0.25 Nm).
Verify the installation

A43/A44 20 2CMC48001M0201
User Manual Revision: C
Step
Action
8
Check that the meter is connected to the specified voltage and that voltage
phase connections and the neutral (if used) are connected to the correct termi-
nals.
9
For a transformer connected meter, check that the current direction of the pri-
mary and secondary current of the external transformers is correct. Also check
that the transformers are connected to the correct meter terminals.
10
Switch on the power. If a warning symbol is displayed, refer to the error codes
in Troubleshooting.
11
Under the menu item "Instantaneous Values" on the meter, check that the volt-
ages, currents, power and power factors are reasonable and that the power
direction is what to be expected (the total power should be positive for a load
that consumes energy). When doing the check the meter should be connected
to the intended load, preferably a load with a current above zero on all phases
to make the check as complete as possible.
Circuit protection Use the information in this table to select the correct fuse for the circuit protec-tion.
