Installation Guide
Revision 12
1 Safety
This document gives details of safe installation and operation of the MultiCube electricity meter. Labels on each meter
give details of equipment ratings for safe operation. Take time to examine all labels before commencing installation.
Safety symbols on the meter have specific meanings as:
Caution Risk of Danger
Refer to Instructions
Danger
Risk of Electric Shock
Safety may be impaired if the instructions are not followed or the meter is used in a manner not
specified by the manufacturer.
Contains no user serviceable parts. Field wiring and commissioning should only be carried out
by qualified personnel, in compliance with applicable national regulations.
e.g. National Electrical Code (NEC) for US; Canadian Electrical Code for Canada
For further Information contact the manufacturer:
Address: Northern Design (Electronics) Ltd: 228 Bolton Road, Bradford, West Yorkshire, BD3 0QW. (UK)
Web: http://www.ndmeter.co.uk
2 Maintenance
The equipment should be maintained in good working order. Damaged equipment must be sent to the manufacturer (or
his authorised agent) for repair. The meter may be cleaned by wiping lightly with a soft cloth. No solvents or cleaning
agents should be used. All inputs and supplies must be isolated before cleaning any part of the equipment.
3 Intended Use
The MultiCube is a precision multi-function electricity monitor which measures system power parameters, including kW,
Volts and Amps and displays them on an LCD. Measured parameters may be sent to remote systems for storage or
display using an optional communications interface (e.g. ModbusRTU RS485, Ethernet or M-Bus).
The MultiCube is intended for indoor use, mounting in the faceplate (panel) of an electrical enclosure with only the front
keypad/display panel remaining accessible to an operator after installation. Panels should be 1mm to 4mm (0.04” to
0.16”) thick with a square cut-out of 92mm (+0.8/-0.0mm) (3.62” +0.03” -0”). Insert the meter from the front of the panel,
slide the panel clips from the rear of the case and push firmly against the panel ensuring even pressure on each clip.
The safety of any system containing the meter as a component remains the responsibility of
the system manufacturer. After installation in a system, the ratings of the overall system, which
reflect the ratings of the meter, must be visible to the user.
A suitably located and easily reached switch or circuit breaker must be included as part of the
installation. This could, for example, be a safety-interlocking device on the door/front panel of
the electrical enclosure. This switch/circuit breaker must be marked as the disconnecting
device for the equipment and must comply with the relevant requirements of IEC 60947-1 and
IEC 60947-3.
Disconnect / Isolate all supplies before commencing installation.

4 Standard Connections
4.1 Current Transducers
Only current transducers which meet the manufacturer’s specifications should be used.
Current Transducer (CT) connections are not galvanically isolated from the voltage inputs and
must therefore not be accessible to the operator after installation. Installed CT cables and any
extensions to these, must not be accessible to the operator.
Minimum Current Transducer Specification:
Input Current Range: 0 to 1.2 In (In = nominal rated current in amps)
Output Voltage: 0.333Vac (at nominal current)
Insulation: 2.2kV Case to Secondary
If long current transducer secondary cables are used care must be taken to avoid pickup of electrical interference. With
suitable low capacitance screened cables, the cable can be extended to 100m (328ft) or more.
4.2 Current Transducer Connections
4.2.1 RJ12 Current Cables
Connection between the meter and each 3-Phase set of current transducers is made using
oRJ12 to RJ12, 6P6C cable:
oCrossover Type PIN 1-6; 2-5; 3-4; 4-3; 5-2, 6-1.
Current cables must be rated for safe use in the electrical enclosure which houses the meter
(e.g. UL1015) and must meet the following minimum specification: Temperature: 105C
(221F); Insulation 300Vac.
4.2.2 Current Transducers
Only current transducers supplied by the manufacturer may be used in conjunction with MultiCube meters. The following list of UL &
CE recognised current transducers has been approved for use.

4.2.3 Current Transducer connection.
The current transducers should be connected to the instrument before the power is applied. The auto detect mechanism
detects the transducer on power up of the instrument.
4.2.4 Current Transducer auto detect.
The instrument is designed to automatically recognise the primary current, and other characteristics, of approved current
transducers.

4.3 Voltage Connections
4.3.1 Voltage Cables
Voltage cables must be rated for safe use in the electrical enclosure which houses the meter
(e.g. UL1015) and must meet the following minimum specification: Temperature: 105C
(221F); Insulation 300Vac.
To maintain proper insulation from the mains supply, the neutral wire should only be used in
power networks where the system neutral is protectively earthed.
4.3.2 Auxiliary Mains Supply
The meter is powered from an auxiliary mains supply which is required to energise the metering circuit and display. This
can be connected in parallel with one of the measurement phase voltages if it is rated correctly.
Ensure the auxiliary mains supply L-N is powered from a correctly rated and fused AC source
as specified on the meter label.

5.8 Configure Serial Port (Modbus Option)
If the Modbus option is fitted (Meter Models - MultiCubex50mV-MODBUS) then the serial communications parameters
may be configured as follows:
Setting
Selection Options
Modbus ID
Set the Range of Modbus IDs
The user sets the first ID and the MultiCube automatically assigns the correct number of
consecutive IDs required (see below).
The maximum start ID is 245 minus the total number of ID’s required by the instrument (see table
below)
Baud Rate
Select the baud rate from: 4800, 9600, 19200, 38400
Parity
Select the parity from: NONE, EVEN, ODD
A number of Modbus IDs need to be reserved for each MultiCube, depending on how many meter points it can measure
as follows:

5.10Configure the Virtual/Residual Meter (optional1)
The multicube950mV can optionally provide an set of metered readings based on a calculation made from its multiple
meter inputs. Two type of configuration are possible for this Virtual Meter:
Virtual Summation Meter
oAdds selected 3-Phase Meters to create measurements of TOTAL METERED LOAD
VIRTUAL SUM = METER1 + METER2 + METER3
Note individual meters may be selected/deselected for the sum
Residual Meter
oUsed to subtract sub-metered loads from an incoming supply measurement. This provides an accurate
measurement of TOTAL UN-METERED loads.
METER1 must measure the 3-Phase incoming load
METER2, METER3 are wired as sub-meters
RESIDUAL = METER1 –(METER2+METER3)
The Virtual Sum or Residual meter displays multiple meter parameters, as a normal multi-function meter (harmonics and
THD are not available)
