Frequently Asked Questions - JF803MID HAGER

How do I install the Hager JF803MID meter?

Mount the meter on a 35mm DIN rail using the snap-on mechanism. Connect the voltage inputs (3-phase 4-wire) to the pluggable terminals and the current inputs via RJ45 connectors from easywire® current transformers. Ensure all connections are tightened to the specified torque and use fuses on the voltage supply as recommended.

What is the difference between the HGR41EWC and HGR41EWMB models?

The HGR41EWC model features RS485 Modbus communication plus a single pulse output, while the HGR41EWMB model features Mbus communication plus a single pulse output. Both are MID certified and have the same measurement functions.

How do I program the CT ratio and VT ratio?

Press the front push-buttons to enter the programming menu (password protected). Navigate to the CT Primary and VT Primary/Secondary settings and input the appropriate values. Note that after 15 minutes in programming mode, certain locked values cannot be changed without returning to factory.

What communication protocols are supported?

The meter supports either RS485 Modbus (RTU) or Mbus, depending on the model. The Modbus version allows configurable baud rate (300-19200), parity, and address (1-255). Up to 32 meters can be connected on a single bus without a repeater, and up to 255 with a repeater.

How to reset energy and demand readings?

Enter the programming menu and select the reset options: Reset Active Energy, Reset Reactive Energy, Reset Apparent Energy, Reset Maximum Demand, etc. Individual resets are available. The reset is only possible if programming mode has not timed out (15 minutes).

Is the meter suitable for billing purposes?

Yes, the JF803MID is MID B+D certified according to the Measuring Instruments Directive (2014/32/EU), making it legal for billing applications in the EU. It meets Class B accuracy for active energy.

What is the accuracy class of the meter?

Active energy accuracy is Class 1 (IEC/EN62053-21) or Class B (IEC/EN50470). Reactive energy accuracy is Class 2 (IEC/EN62053-23). Voltage and current accuracy is 0.5% of full scale, and power factor accuracy is 1% of unity.

How to connect the pulse output to a remote monitoring system?

The pulse output is a solid-state relay with a maximum current of 100mA and voltage range of 5…27VDC. Connect it to a pulse counter or PLC input. The pulse duration can be programmed from 100ms to 2s. The pulse output corresponds to kWh consumption.

Can I daisy-chain multiple meters?

Yes, the meter has a voltage OUT connector that allows daisy-chaining up to 32 meters from a single voltage supply. This simplifies wiring in multi-meter installations. Ensure the total current does not exceed the fuse rating (max 3A).

What maintenance does the meter require?

No regular maintenance is required. Keep the front panel clean using a dry or slightly damp cloth. Do not use solvents or abrasive cleaners. Ensure the ventilation slots are not obstructed. Periodically check that all terminal connections are tight.

Product Description

The HGR41EW series are part of the easywire ^® family of meters. The easywire ^® system has been designed to save up to 90% installation time compared to a standard meter and current transformer installation.

This MID approved DIN rail mounted multifunction energy meters is suitable for monitoring energy consumption and many other electrical parameters in industrial and commercial applications. These meters may be used in three phase applications and have been certified for billing purposes.

A high efficiency white backlit LCD display provides clear indication of measured values in all light conditions.

Push-buttons on the front of the meter allow the user access to the display page required.

The meter is available in two versions:-

- With single pulse output and RS485 Modbus communication

- With single pulse output and Mbus communication

The unit is housed in a compact four module width housing suitable for DIN rail mounting.
