Installation

Attention:Installation should be performed by a qualified professional.
Ensure all the parts are included in your kit.
MUN53.410 Modules are used for gateways and meters and concentrators.
Take installing it on an electricity meter.

Assemble MJN53.R410 into NIC

Follow the steps below to assemble the NIC.

The NIC is connected to antenna through the adapter, and then tighten it

The NIC is connected to the meter via a serial port, plug and play

Install the meter

A) Installation tools

B) Preparation before installation

• The meter should be installed in ventilated and dry place to ensure the meter’s safety and reliability. In the dirty or risky area, the meter should be installed in a protection box.
• Meter should be fixed on a firm, fire-resistant and stable support.
• Before installation, please check if the meter has been damaged during the transportation(damage of meter cover, hanger, seal, and LCD display, etc)
• As the internal part of the electrical meter is composed by the delicate electronic components, the meter should be carefully protected during the installation in order to avoid any damage.

WARNING

Make sure that the power is cut off before the meter installation, otherwise it will cause a threat to life. The fuse should be disconnected and put it in a safe place to avoid the accidental power-on.

C) Installation procedure

1. Select the proper position according to the meter dimensions, and indicate fixing points of the meter on the installation panel.

2. Drill down holes on previously marked positions. (make sure that there’s no cable behind before punching, avoid ruining the cable and threatening personal safety)

3. Open the meter terminal cover, and adjust the height of hanger.

4. Using the vertical installation method, the meter is hanging on the hanger screw, and fixed on the bottom by two screws. Need to ensure that the 3 screws are completely banned, and the meter is installed firmly, without shaking.
   NOTE To ensure the installation stability, the diameter of hanger screw must be greater than 11mm, and the diameter of bottom fixed screws must be greater than 7mm.

5. Cut the cable to the required length and use the wire stripper to uncover the cable. The recommended bare metal length after stripping is at least 20mm for this series of products.
   WARNING We insist on the recommended length of the stripped wire to ensure that the bare metal part is long enough and can be fixed by two connection screws at the same time. However the bare part should not exceed the terminal box wiring holes, ensure the safety and insulation effect.

6. When using a small sectional cable, such as 4mm squared, the cable must be placed in the medium to ensure that the screw is well tightened without deviation.

7. The cables should be connected correctly according to the wiring diagram and the terminals should be tightened during the installation in order to avoid any damage caused by bad connection.
   NOTE The bad fixing of connection screws will lead to the raise of resistance, which can lead to electrical energy loss and heating of terminals. The heating of component is risky. Besides, 1mQ contact resistance in a circuit of 80A will result in 6.4 W power losses.

8. The cables should be connected correctly according to the definition of the auxiliary terminal (such as pulse output, signal input or RS485 communication).
   WARNING Be attention to not be mistakenly connected the auxiliary terminal to the voltage or current line, so as to avoid damage to meter.

9. Check connecting wire carefully and avoid any error (such as the reverse wiring for the incoming and outgoing lines, the wrong connection of live and neutral, the bad fixing of screws).
   NOTE To ensure the correct wiring, it is recommended to use the appropriate testing tools (such as multi-meters) for input/output test.

10. Close the terminal cover, and sealed it.
    NOTE Please to ensure that the terminal cover is closed tightly, otherwise it will cause the meter relay cut off due to terminal cover open(If required, can add this relay off through terminal cover open).

Testing after installation

• Insert the fuse, connect to the grid
• Check the meter display, is there any malfunction indication, phase inverse, cover open, or strong magnetic field, no current indictor.
• Press button to display voltage value, double confirm the voltage.
• Check the relay is on the right position (if the symbol is shown on the LCD),

Un-installation

1. Remove the fuse and power off the meter.
   WARNING Make sure that the power is cut off before the meter un- installation, otherwise it will cause a threat to life. The fuse should be disconnected and put it in a safe place to avoid the accidental power-on.

2. Cut off the terminal cover seal, and remove the terminal cover.

3. Use the voltage test equipment (such as multimeter) to test meter connecting wire and confirm power-off before go to the next operation.

4. Use the appropriate screwdriver to unscrew the meter auxiliary terminal screws and remove the connecting wires.

5. Use the appropriate screwdriver to unscrew the current connection screws and remove the connecting wires.

6. Using the appropriate screwdriver to unscrew the meter fixing screws.

7. Take off the meter.
   CAUTION The meter un-installation should be done according to the above mentioned order. Be attention to prevent meter from dropping down, which will cause injuries and damage the meter itself.

8. If necessary, please replace a new meter.
   WARNING If a new meter cannot be installed for the moment, please envelop the voltage and current connection cables in insulating material and avoid exposing any bare metal part, otherwise it will pose a threat to life.

9. How to use:
   Power on the meter, the module will be in the working, when the module receives the user’s command information, the module will return the corresponding information to the user device.
