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 instrument must 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.

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.

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.

• 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.
• 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.
• 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.

• Suggest install 1A fuse in the fire line side.
• For the areas with poor power quality, suggest install lightning surge suppressor and rapid burst suppressor to prevent lightning strikes.

Connection Terminal
Meter Base Terminals:

• Upper row: Digital input, Current Sampling (4-6) Pulse Output, Relay Output
• Lower row: Voltage sampling, Current Sampling (1-3), Display port, Communication, Power Supply

Notes: The terminal pin will change depends on customer order; please refer to the label on the meter!

Typical wiring for 18 channels 

IMPORTANT REMARK!
If power = -0.01 is shown for any of the phases and voltage and current are not zero for this phase, check out following points:

• Assure that A, B and C phases coincide in voltage and current.
• Correct polarity? Reverse the current transformer placed at this phase.
