Notices
FCC Part 15 notice
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 generates, 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 to an outlet on a circuit different from that to which the receiver is
connected.
• Consult the dealer or an experienced radio/TV technician for help.
This Class B digital apparatus complies with Canadian ICES-003.

Chapter 1 Safety precautions
Installation, wiring, testing and service must be performed in accordance with all local and national
electrical codes.
Carefully read and follow the safety precautions outlined below.
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
• Apply appropriate personal protective equipment (PPE) and follow safe electrical work practices.
See NFPA 70E in the USA or applicable local standards.
• This equipment must only be installed and serviced by qualified electrical personnel.
• Turn off all power supplying this device and the equipment in which it is installed before working
on the device or equipment.
• Always use a properly rated voltage sensing device to confirm power is off.
• Before performing visual inspections, tests, or maintenance on this equipment, disconnect all
sources of electric power. Assume that all circuits are live until they have been completely
de-energized, tested and tagged. Pay particular attention to the design of the power system.
Consider all power supply sources, particularly the potential for backfeed.
• Replace all devices, doors and covers before turning on power to this equipment.
• Do not exceed the device’s ratings for maximum limits.
Failure to follow these instructions will result in death or serious injury.
WARNING
UNINTENDED OPERATION
Do not use the meter for critical control or protection applications where human or equipment safety
relies on the operation of the control circuit.
Failure to follow these instructions can result in death, serious injury or equipment damage.
WARNING
INACCURATE DATA RESULTS
• Do not rely solely on data displayed on the front panel or in software to determine if the device is
functioning correctly or compliant with all applicable standards.
• Do not use data displayed on the front panel or in software as a substitute for proper workplace
practices or equipment maintenance.
Failure to follow these instructions can result in death, serious injury or equipment damage.

Overview of meter functions
The meters provide the essential measurement capabilities (for example, current, voltage, and
energy) required to monitor a 1- or 3-phase electrical installation.
The key features of the meters are:
• measurement of active and reactive energy,
• Multi Tariffs (up to 4) controlled by internal clock, digital inputs or communication,
• MID compliance for many of the meters,
• pulse outputs,
• display (current, voltage, and energy measurements),
• communications via Modbus, LonWorks, M-Bus or BACnet protocols.

Functions Advantages Applications Meter
M-Bus communications
Modbus communications
BACnet communications
LonWorks communications
Four quadrant calculation
Measurement of active, reactive
and apparent energy.
Programmable digital input
Programmable digital output
Communicate advanced parameters using
M-Bus protocol
Communicate advanced parameters using Modbus
protocol
Communicate advanced parameters using BACnet
MS/TP protocol
Communicate advanced parameters using LonWorks
communications
Identification of imported and exported active and
reactive energy allows you to monitor energy flow in
both directions: delivered from the utility and
produced on-site
Allows you to monitor energy consumption and
production
Can be programmed to:
Count pulses from other meters (gas, water, etc.)
Monitor an external status
Reset the partial energy accumulation and start a
new period of accumulation
Can be programmed to:
be an active energy (kWh) pulse output, with a
configurable pulse weight
Alarm on a power overload at a configurable pickup
setpoint
M-Bus network integration
Modbus network integration
BACnet network integration
LonWorks network integration
Ideal for facilities with back-up generators or
green power capabilities (for example, solar
panels or wind turbines)
Manage energy consumption and make
informed investment to reduce your energy bill
or penalties (for example, installing capacitor
banks)
This allows for monitoring of:
WAGES
Intrusion (for example, doors opening) or
equipment status
Energy usage
This allows you to:
Collect pulses from the meter with a Smartlink
system, PLC or any basic acquisition system
Monitor power levels at a detailed level and to
help detect an overload before the circuit

HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
• Apply appropriate personal protective equipment (PPE) and follow safe electrical work practices.
See NFPA 70E in the USA or applicable local standards.
• This equipment must only be installed and serviced by qualified electrical personnel.
• Turn off all power supplying this device and the equipment in which it is installed before working
on the device or equipment.
• Always use a properly rated voltage sensing device to confirm power is off.
• Replace all devices, doors and covers before turning on power to this equipment.
• Do not exceed the device’s ratings for maximum limits.
Failure to follow these instructions will result in death or serious injury.
Mounting the meter on a DIN rail
1. Position the 2 upper slots on the rear of the meter onto the DIN rail.
DANGER
2. Press the meter against the DIN rail until the locking mechanism engages. The meter is now
attached to the rail. Make sure that the device is not tilted following installation.

DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
• Apply appropriate personal protective equipment (PPE) and follow safe electrical work practices.
See NFPA 70E in the USA or applicable local standards.
• This equipment must only be installed and serviced by qualified electrical personnel.
• Turn off all power supplying this device and the equipment in which it is installed before working
on the device or equipment.
• Always use a properly rated voltage sensing device to confirm power is off.
• Replace all devices, doors and covers before turning on power to this equipment.
• Do not exceed the device’s ratings for maximum limits.
Failure to follow these instructions will result in death or serious injury.
Voltage input protection
The meter’s voltage inputs must be wired to fuses/breakers and a disconnect switch. If using a voltage
transformer (VT), both primary and secondary sides of the VT must be fused and switched.
• Clearly label the device’s disconnect circuit mechanism and install it within easy reach of the
operator.
• Fuses / circuit breakers must be:
— installed in accordance with all local and national electrical codes and standards, and
— rated for the installation voltage, available fault current, and sized for connected loads.
• Fuse for neutral is required if the source neutral connection is not grounded.
Current input protection for 1 A and 5 A meters
For all connected current inputs on 1 A and 5 A meters with external CTs, use a CT shorting block to
short-circuit the secondary leads of the CTs before removing the current input connections to the
meter.
NOTE: Ground any unused current inputs on 1 A and 5 A meters.
