4. Mechanical mounting

Please ensure that the operating temperature limits are not exceeded when determining the place of mounting (place of measurement).

By installing, the device becomes part of an electrical power installation that must be designed, operated and maintained in accordance with country-specific regulations so that the installation is safe and provides prevention against fire and explosion as far as possible.

The standard version of the DM5000 can be clipped onto a top-hat rail according to EN60715. Orientation as shown.

It is the task of this installation to ensure that dangerous connections of the device can not be touched during operation and that the spread of flames, heat and smoke from the interior is prevented. This may be done by providing an enclosure (e.g. case, cabinet) or using a room accessible to qualified personal only and compliant with local fire safety standards.

The device can also be mounted that the front of the device protrudes through a cut-out in the enclosure. So the operating buttons and the display become accessible. With centric mounting using the below maximum cut-out a gap between enclosure and device results, which does not exceed 2.5mm on each side.

All voltage measurement inputs must originate at circuit breakers or fuses rated 5 Amps or less. This does not apply to the neutral connector. You have to provide a method for manually removing power from the device, such as a clearly labeled circuit breaker or a fused disconnect switch in accordance with IEC 60947-2 or IEC 60947-3.

When using voltage transformers you have to ensure that their secondary connections never will be short-circuited.

• 0.5…0.6Nm

• 4.42…5.31 lbf in

• 1 x 0.5 ... 2.5mm

or 2 x 0.5 ... 1.0mm2

• 1 x 20 AWG…14 AWG or 2 x 20 AWG…17 AWG

• 1 x 0.5 ... 2.5mm

or 2 x 0.5 ... 1.5mm2

• 1 x 20 AWG…14 AWG or 2 x 20 AWG…16 AWG

5.6 Power supply

A marked and easily accessible current limiting switch in accordance with IEC 60947-2 has to be arranged in the vicinity of the device for turning off the power supply. Fusing should be 10 Amps or less and must be rated for the available voltage and fault current.

5.7 Relays

When the device is switched off the relay contacts are de-energized, but dangerous voltages may be present.

Relays are available for device versions with corresponding I/O extensions only.

5.8 Digital inputs

The device provides a standard passive digital input. In addition, depending on the device version, there may be 4-channel passive or active digital input modules available.

Usage of the standard digital input

► Status input ► Meter tariff switching

Usage of the inputs of the optional input modules

► Counting input for pulses of meters for any kind of energy (pulse width 70…250ms) ► Operating feedback of loads for operating time counters ► Trigger and release signal for monitoring functions

Passive inputs (external power supply with 12 / 24 VDC required)

The power supply shall not exceed 30V DC!

5.9 Digital outputs

The device has two standard digital outputs for which an external 12 / 24 VDC power supply is required.

The power supply shall not exceed 30V DC!

Usage as digital output

► Alarm output ► State reporting ► Pulse output to an external counter (acc. EN62053-31) ► Remote controlled output

1) Recommended if input impedance of counter

> 100 kΩ

The width of the energy pulses can be selected within a range of 30 up to 250ms, but have to be adapted to the external counter mechanism.

Electro mechanical meters typically need a pulse width of 50...100ms.

Electronic meters are partly capable to detect pulses in the kHz range. There are two types: NPN (active negative edge) and PNP (active positive edge). For this device a PNP is required. The pulse width has to be ≥ 30ms (acc. EN62053-31). The delay between two pulses has to be at least the pulse width. The smaller the pulse width, the higher the sensitivity to disturbances.

5.10 Analog outputs

Analog outputs are available for devices with corresponding I/O extensions only. See nameplate. Analog

outputs may be remote controlled.

Connection to an analog input card of a PLC or a control system

The device is an isolated measurement device. The module outputs are galvanically connected, but the modules isolated from each other. To reduce the influence of disturbances shielded a twisted-pair cables should be used. The shield should be connected to earth on both opposite ends. If there are potential differences between the ends of the cable the shield should be earthed on one side only to prevent from equalizing currents.

Under all circumstances consider as well appropriate remarks in the instruction manual of the system to connect.

5.11 Modbus interface RS485

Via the optional Modbus interface measurement data may be provided for a superior system. However, the Modbus interface cannot be used for device parameterization.

1) One ground connection only. This is possibly made within the master (PC).

The signal wires (A, B) have to be twisted. GND (C/X) can be connected via a wire or via the cable shield. In disturbed environments shielded cables must be used. Supply resistors (Rs) have to be present in bus master (PC) interface. Stubs should be avoided when connecting the devices. A pure line network is ideal.

You may connect up to 32 Modbus devices to the bus. A proper operation requires that all devices connected to the bus have equal communication settings (baud rate, transmission format) and unique Modbus addresses.

The bus system is operated half duplex and may be extended to a maximum length of 1200 m without repeater.

5.12 Fault current detection

Use only transformers intended for this application, according to our current transformer catalog, or transformers that fulfill the above specification. Using transformers with divergent specifications may damage the measu

The current transformers including the conductor isolation must guarantee in total a reinforced or double insulation between the mains circuit connected on the primary side and the measuring inputs of the device

Only one measurement range may be connected per measuring channel!

The COM connectors of both measurement channels are internally connected.

For 2mA inputs a connection monitoring (breakage) is implemented. An alarm state is signaled for the respective measurement channels if either the current disconnected or the connection to the transformer is interrupted.

Each fault current module provides two channels for monitoring differential or fault currents in earthed AC current systems. In any case, measurement has to be performed via suitable current transformers, a direct measurement is not possible. The module is not suited for monitoring operating currents of normally live conductors (L1, L2, L3, N).

Measurement ranges

Each channel provides two measurement ranges:

a) Measurement range 1A

• Application: Direct measurement of a fault or earth wire current

• Meas. transformer: Current transformer 1/1 up to 1000/1A; 0.2 up to 1.5VA;

Instrument security factor FS5

b) Measurement range 2mA

• Application: Residual current monitoring (RCM)

• Meas. transformer: Residual current transformer 500/1 up to 1000/1A

Rated burden 100 Ω / 0.025 VA up to 200 Ω / 0.06 VA

Example: Fault current monitoring in a TNS system

Hints

(1) If the current transformers for the fault current detection needs to be grounded on the secondary

side this has to be done via the COM connector.

(2) Note that all conductors have to pass through the opening of the

residual current transformer in the same direction.

(3) A possible fault current flows through the protective

earth conductor (PE). It can only be detected if the PE conductor is not routed through the residual current transformer. If this cannot be avoided, e.g. due to using a multi-wire cable with all conductors, the PE conductor must be returned through the transformer.

(4) The cable or individual conductors should be routed through the

transformer as centered as possible in order to minimize measurement errors.

(5) Neither the current transformers nor the measurement leads should be mounted or installed close to

strong magnetic fields. Measurement lines should also not be laid in parallel to power lines.

(6) For measurement range 1A only: The rated output of the transformer must be chosen that it is

reached when the rated secondary current (1A) flows. Consider that the burden of the transformer is not only made up by the burden of the measurement input, but also by the resistance of the measurement lines and the self-consumption of the transformer (copper losses).

 A rated output selected too low leads to saturation losses in the transformer. The secondary

rated current can no longer be reached as the transformer reaches its limits before.

 A rated output selected too high or an exceeding instrument security factor (>FS5) may cause

damage to the measuring inputs in case of overload.

(7) For the connection of the transformer to the fault detection module use …

 Conductor cross sections of 1.0 up to 2.5mm

(16-14 AWG)

 Pairwise twisted conductors in case of short cable lengths

 Shielded cables (shield grounded on one side only) in disturbed environment or in case of long

cable lengths

5.15 GPS time synchronization

Only use the receiver Garmin GPS 16x-LVS (article

The optional GPS connection module serves for connecting a GPS receiver as a very accurate time synchronization source for the measurement device. The GPS receiver, available as an accessory, is used as outdoor antenna to process data from multiple GPS satellites simultaneously.

GPS receiver

no. 181‘131), offered as an accessory. This device is preconfigured by us and provides the required time information (sentences) without further configuration effort.

• Protection: IPx7 (waterproof)

• Operating temperature: -30…80°C

• Storage temperature: -40…80°C

• 1Hz pulse accuracy: 1μs

• Connector: RJ45

Choosing a mounting location

For a correct operation the GPS receiver requires data from at least 3 satellites at the same time. Therefore position the receiver so that the clearest possible view of the sky and horizon in all direction is obtained. This can be on the roof of a building, at best without reception being restricted by other buildings or obstacles. Avoid mounting the receiver next to large areas of conductible material, as this may cause poor signal reception. It should be also not closer than 1 meter away from any other antenna.

If lightning protection is required, this must be provided by the user.

Mounting the GPS receiver

• The GPS receiver Garmin GPS 16x-LVS can be flush mounted by means of 3 M4 screws.

• 120° distribution over a circle of ø71.6mm

• Thread length max. 8mm. Using longer

screws may damage the GPS receiver.

PM 1001484 000 08 Device handbook SINEAX DM5000 28/96

Connecting the GPS receiver

When connecting a GPS receiver for the first time or when it has been out of operation for a long time, it may take up to 1 hour for finding enough sa GPS receiver operation and thus for a reliable time synchronization.

Never connect the RJ45 connector of the connecting cable directly to a network device such as a router or switch. These devices could be damaged.

The GPS receiver is plugged directly into the GPS connection module. The connection cable has a length of 5 m. It may be extended using an RJ45 coupling and an Ethernet cable. The connection cable should not be laid in parallel to live conductors. Twisting or sharp kinking of the cable should be avoided.

Commissioning

• In the settings menu change time synchronization to „NTP server / GPS“

• Check the time synchronization status

• The time synchronization can be restarted by switching the time synchronization off and on again.

• Time synchronization via GPS and NTP server may work in parallel. If both synchronization sources

are available, the system uses the more accurate time source, which is normally GPS.
