1. - SUMMARIZE
The MCM1000 Series provides a compact and robust metering solution, enable reliable monitoring
of building electrical loads with a low installation cost-per-point by combining sub-metering. The
unit performs real-time metering, measures energy consumption for max 18 channels circuits for
single phase or 6 channel for three phase circuits.
Advanced communications options including Modbus via RS485, I/O communications provide for
extensive reliable data exchange. Multiple units can be connected together to meter unlimited
number of circuits. The versatility of MCM1000 meters are ideal for multi-tenant or departmental
metering applications within office towers, condominiums, apartment buildings, shopping centers
and other multi-user environments.
Measurement Function
Voltage: Line Voltage; Phase Voltage
Current: Total Current; Current per channel
Power and Power Factor: Total power Reactive Power, Apparent Power, Power Factor and for
per channel
Frequency: System Frequency
Energy Function

4.- INSTALLATION AND START-UP
The manual you hold in your hand contains information and warnings that the user
should respect in order to guarantee a proper operation of all the instrument functions
and keep it in safety conditions. The instrumentmust not be powered on and used until
its definitive assembly is on the cabinet’s door.
If the instrument is not used as manufacturer’s specifications, the protection of the
instrument will be damaged.
When any protection failure is suspected to exist (for example, it presents external visible
damages), the instrument must be immediately powered off. In this case contact a qualified
service representative.
4.1.- Installation
Mounting
This meter is DIN rail mounted, which fits 35 mm standard rails. Keep all connections into the
cabinet. Note that with the instrument powered on, the terminals could be dangerous to touch and
cover opening actions or elements removal may allow accessing dangerous parts. Therefore, the
instrument must not be used until this is completely installed.

35mm Din Rail
MCM1000
Notes:
Input signal: MCM1000 using a separate acquisition calculate for each measurement channel, to
ensure consistent in use, for different load forms, it's a variety of connection mode. Access wire
shall be met: the current 2.5 square mm, voltage of 1.5 square millimeters.
A. Voltage input:
Input voltage should not exceed the rated input voltage products (100V or 400V),
Otherwise, you should use external CT. Suggest 1A fuse be installed in the voltage input side.
B. Current Input:
Standard input current is 5A, if greater than 5A should use external CT.
When the CT is connected with other instruments, make sure wiring methods be used in series.
Before remove the current input connection, must be sure to disconnect the primary circuit or
shorted secondary circuit of CT. In order to facilitate disassembly, please do not connect to CT
directly, and the terminal block is suggested.
C. Please make sure that the input voltage and current corresponding to the same phase
sequence, and the same direction; Otherwise, the Values and symbols will be wrong!!
(Power and Energy)
The input network configuration of instrument depends on the CT number of the system:
in the condition of 2 CT, select the three-phase, three-lines two components;

in the condition of 3 CT, select the three-phase, four-lines three component mode.
Instrument connection mode, set of the instrument (programming input network NET) should be
the same load wiring as measured wiring. Otherwise, the measurement instrument will lead to
incorrect voltage or power.
In three-phase three-wire mode, the measurement and shows the line voltage;
In three-phase four-wire mode, the measurement and shows the phase voltage.
Auxiliary power:
MCM1000 Series with universal (AC / DC) power input, if not for a special statement, we provide
the 220VAC or 110V/DC power interface for standard products. Instruments limit work power
supply: AC: 85-265V / DC: 100~300V, please ensure that the auxiliary power can match with
MCM1000 series meter to prevent damage to the product.
A. Suggest install 1A fuse in the fire line side.
B. For the areas with poor power quality, suggest install lightning surge suppressor and rapid burst
suppressor to prevent lightning strikes.
