Purpose
This technical manual contains the following information:
•Installation instructions, construction, characteristics and maintenance information
•Performance and technical data
Target Group
The contents of this technical manual are intended for technically qualified personnel of energy
supply companies responsible for the system planning, installation, commissioning, operation,
maintenance, decommissioning and disposal of the meters.

Conditions
This technical manual is for personnel who are qualified and have received instructions in basic
electrical principles, including safety procedures for installation of energy meters.
Safety Warnings
The following safety precautions must be observed during all phases of operation, service, and
repair of this device. Failure to comply with these precautions or with specific warnings elsewhere
in this manual violates safety standards of design, manufacture, and the intended use of the
metering instrument. Landis+Gyr, Inc. assumes no liability for the customer's failure to comply
with these requirements.
WarningAll applicable electrical codes and standards must be followed.
Failure to use sufficient insulation on option or I/O cables connecting to the
meter through the mounting device could cause serious personal injury, property
damage, and/or death.
!
Any work on, or near, energized meters, meter sockets, or other metering equipment can
present a danger of electrical shock. All work on this product should be performed only by
qualified electricians and metering specialists in accordance with local utility safety practices,
utility requirements, and procedures outlined in Chapter 14 of The Handbook for Electricity
Metering (9th Edition). The information contained within this manual is intended to be an aid
to qualified metering personnel. It is not intended to replace the extensive training necessary
to handle metering equipment in a safe manner.
Use care when servicing with the power on.
!
Warning
The use of I/O cables in ungrounded services could cause serious personal injury,
property damage, and/or death
The
FOCUS does not have an auto-ranging power supply. Care should be taken to ensure
that meters are installed correctly, matching meter form and voltage with the installation.

FCC Information:
This device complies with part 15 of the FCC rules. Operation is subject to the following two
conditions:
(1) This device may not cause harmful interference, and
(2) This device must accept any interference received, including interference that may
cause undesired operation.

(3) For RF exposure, service personnel are to maintain a minimum of 20cm from the
RF communications transmitter once installed.
Changes or modifications not expressly approved by Landis+Gyr could void
the user’s authority to operate the equipment.
Do not change the original antenna without pre-approval from the original
meter manufacturer. This will violate the FCC regulations of using the
radio.
Note:
Some Focus meters may contain AMR modules with RF communications. This equipment
has been tested and found to comply with the limits for a class B digital device, pursuant to
part 15 of the FCC Rules. These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment uses and can radiate radio
frequency energy and, if not installed and used in accordance with the instructions, may cause
harmful interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by turning the
equipment off and on, the user is encouraged to try to correct the interference by one or more
of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to
which the receiver is connected.
- Consult Landis+Gyr or an authorized technician for help.
Following are FCC identification numbers for radio systems currently used on FOCUS:

1. Introduction To The FOCUS
The FOCUS meter was designed to be a low-cost, solid-state, kWh-only meter as an alternative
metering and AMR platform to the induction meter. The meter is based on reliable, field proven digital
multiplication measurement technique. The meter platform will measure energy accurately over
varying environmental conditions. It is designed to be stable over its long expected life. A diagram of
basic operation is noted below.
