Safety Notes

Incorrect installation, commissioning or operation can lead to serious damage to property and personal injury and to death.
Please read these instructions carefully before installing, commissioning and using the ZDUE-450-PLUS-VII. Use the appliance only as described in the data sheet and the manual.
The ZDUE-450-PLUS-VII meets the requirements of safety standard EN 62368-1 (protection class 2).

Qualified personnel
Installation and commissioning of the ZDUE-450-PLUS-VII and the accessories may only be carried out by electricians. They must be trained and qualified to detect and avoid hazards and to install, commission, ground and mark appliances, systems and circuits in accordance with the standards and recognized rules of technology.

Connection to the house installation
An easily accessible, all-pole circuit breaker in the power supply circuit is required for the house installation. Alternatively, a single-pole circuit breaker can be used in the outer conductor as long as a distinct neutral conductor has been integrated into the supply line. Observe country-specific regulations. In Germany, the circuit breaker must at least meet the requirements of the DIN VDE series 0100 standards (see CENELEC HD384; IEC 60364).

For the house installation, there must be an installation fuse that complies with the DIN VDE series 0100 standards (see CENELEC HD384; IEC 60364) and is properly adapted to the cable cross-section of the power supply line. The additional short-circuit protection must have a selectivity of I > 1500A.
The appliance is not suitable for connection to an electrical supply network with IT configuration (IT system).

Cable Routing
The space between antenna/data lines and lines carrying dangerous voltages must be at least 10 mm.

Location
Never use the ZDUE-450-PLUS-VII in areas where the operation of radio equipment is prohibited. The appliance contains a radio transmitter, which can possibly impair the function of medical electrical appliances such as hearing aids or cardiac pacemakers.
The ZDUE-450-PLUS-VII is suitable for use in overvoltage category III. If the appliance is likely to be exposed to higher transient over voltages than those in overvoltage category III when connected, it will be necessary to take further safety precautions for the installation.

Antenna Installation
Indoor and outdoor antennas of the appliance may be installed and operated only with a minimum distance of 20 cm from humans.
The antennas must be installed and operated so that they do not interfere with other antennas or devices.
When using a directional antenna, observe the legal limit for electromagnetic fields (0 Hz to 300 GHz) in public areas. For details, see Council Recommendations 1999/519/EC of 12 July 1999.

It is mandatory, that the installation of an outdoor antenna must be carried out by a qualified electrician. The standards EN 60728-11 and VDE 0855-300 as well as any other national installation guidelines for lightning protection must be followed.

Intended Use

The ZDUE-450-PLUS-VII is an appliance designed for the remote inquiry and the remote monitoring of electricity, heat, gas and water meters. It is design to be used in mobile radio networks.

Opening the device

In order to insert the SIM card or to access the DIP switch, you first have to open the device:

1. First disconnect all the poles of the device from the electricity supply if it is plugged in there.
2. Now unscrew the screw in the terminal cover and remove the cover.
3. Now remove the device lid.

1. Mobile Radio Net Status / Error LED
2. Status LEDs
3. Service connector (optional)
4. DIP switch
5. SIM card holder
6. SMA antenna connector (SMA or FAKRA-D)
7. Service push button
8. Terminal block (RS485)
9. RS232 interface
10. Terminal block
11. Current Loop LED

Altering the device settings
Using the DIP switch (4) you toggle between the both operating modes, meter mode and AT command mode.
In meter mode (OFF), the device can be adjusted locally via one of the meter interfaces or remotely via communication commands according to EN 62056-21. In this case, the device will then operate using the parameters that have been set.

Setting the PIN of the SIM card

In order to operate the ZDUE-450-PLUS-VII, you will require a plug-in SIM card (1,8V only) from a mobile radio network operator.
A ZDUE-450-PLUS-VII having factory default settings expects a SIM card with a PIN 0000. The PIN setting of the ZDUE-450-PLUS-VII can be changed in the device settings.

Inserting the SIM card

Insert the SIM card as follows:

1. Open the SIM card holder by gently pressing the lid towards the edge of the device, flip it up and insert the SIM card into the slot in the holder. The gold-plated contacts on the SIM card have to lie on the gold-plated contacts of the holder when the holder is closed.
2. Close the lid of the SIM card holder and lock it by pressing it gently back towards the center of the device. You will feel it click into place.
3. Now replace the device lid and the terminal cover.

Connecting the device

First connect the meter to the device and then connect the power supply.

The device is equipped with 3 different meter interfaces, which are wired in parallel.

RS232 interface (RJ45 jack)

Signals and levels according to V.24 / V.28. All other pins are reserved.

RS485 interface (terminal block)

Dual-wire RS485 interface to connect up to 32 transceivers. The bus connection is terminated to Z=120 Ω (nominal) (RT+ to RT-) and the cable length is limited to 1000m.

CL1 interface (terminal block) / optional

20mA power interface (current loop) to connect meters with the power supply interface according to DIN EN 62056-21. Approx. 4 meters can be connected to this interface.

The CL1 interface is optional. Devices without CL1 interface do not contain RTX- / RTX+ terminals. Please refer to the label of the terminal block.

**Important:** If no meter is connected to the CL1 interface, the RTX- and RTX+ contacts need to be short-circuited. Otherwise, the other interfaces will not operate.

Auxiliary power source (HS; terminal block)

Auxiliary power supply of 9V / max. 100mA

The auxiliary power supply is not available for all the ZDUE-450- PLUS-VII models.

Power supply (terminal block)

N
Inom = 120mA / 40mA

Connecting the antenna
Observe the safety instructions for antenna mounting.
Follow the instructions that came with your antenna. The antenna must have the following characteristics: passive, gain <2 dBi, VSWR <2,0:1, impedance 50 Ω, adapted for the used frequency bands. Use antennas from the accessory range of the ZDUE.

The antenna is connected to the type SMA or type FAKRA-D antenna jack (ANT). The antenna should be installed to ensure adequate signal quality. Ensure that there are no large metal objects (e.g. reinforced concrete) near the antenna, as these will adversely affect the signal quality.
