Product Information

The BJ-MCM2403-V Series Multi-Channel Circuit Metering System is
a compact and robust metering solution that provides reliable
monitoring of building electrical loads with a low installation
cost-per-point by combining submetering. The unit performs
real-time metering, measures energy consumption, multi-tariff
time-of-use (TOU), and monitors power quality of 4 channels
circuits for three-phase circuits.

The MCM2403-V Series has advanced communication options,
including Modbus via RS485, I/O communications, providing for
extensive reliable data exchange. Multiple units can be connected
together to meter an unlimited number of circuits. The versatility
of the MCM400 meters is ideal for multi-tenant or departmental
metering applications within office towers, condominiums, apartment
buildings, shopping centers, and other multi-user environments.

Product Usage Instructions

Before using the BJ-MCM2403-V Series Multi-Channel Circuit
Metering System, carefully read the user manual and fully
understand the implications and correct guidance of operations in
accordance with the user manual. This will help you make better use
of the DC Energy Meter and help to solve various problems at the
scene.

Follow these instructions when using the meter:

1. Before turning on the power supply, ensure that the power
   supply is within the provisions of the instrument.
2. During installation, ensure that the current input terminal is
   non-open and voltage input terminals are non-short circuit.
3. Ensure that the instrument wiring is consistent with the
   internal system settings.
4. When communicating with the PC, ensure that instrument
   communication parameters are consistent with the PC.

Please read the user manual carefully and save this document for
future reference.

3.- INSTALLATION AND START-UP

User Manual

The manual you hold in your hands contains information and warnings that the user should respect in order to guarantee a proper operation of all the instrument functions and keep its safety conditions. The instrument must not be powered and used until its definitive assembly is on the cabinet’s door.
Whether the instrument is not used as manufacturer’s specifications, the protection of the instrument can 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.
3.1.- Installation
Mounting
Instrument is to be mounted on 35mm Din-rail. Keep all connections inside 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:
Auxiliary power:
MCM2403-V meter with AUX power input, if not for a special statement, we provide the 85265VAC/DC power interface for standard products. Please ensure that the auxiliary power match meter access to prevent damage to the product.
