2. Safety notes

Device may only be disposed in a professional manner!

The installation and commissioning should only be carried out by trained personnel.
Check the following points before commissioning:

- that the maximum values for all the connections are not exceeded, see „Technical data“ section,

- that the connection wires are not damaged, and that they are not live during wiring,

- that the power fl ow direction and the phase rotation are correct.

The instrument must be taken out of service if safe operation is no longer possible (e.g. visible damage). In this
case, all the connections must be switched o . The instrument must be returned to the factory or to an authorized
service dealer.

It is forbidden to open the housing and to make modifi cations to the instrument. The instrument is not equipped
with an integrated circuit breaker. During installation check that a labeled switch is installed and that it can easily
be reached by the operators.

Unauthorized repair or alteration of the unit invalidates the warranty.

3. Device overview

3.1 Brief description

The universal measuring device SIRAX BT5700 is suited for fi xed mounting and the measurement of Voltage, current, frequency, power, energy
(active / reactive / apparent), power factor, phase angle, etc in low voltage switchgear. The units are designed for unbalanced load network forms
of 3-phase mains with 3- or 4-wire.

4. Mechanical mounting

The SIRAX BT5700 is designed for panel mounting.

4.1 Mounting

Dimensional drawing BT5700: See section 11

Any mounting position is possible. Device may be clipped onto a top-hat rail according EN50022 in a cabinet.

4.2 Demounting of the device

Disassembly of the device requires that all connected wires be without current. First, remove all push terminals and the wires of the current and
voltage inputs. Ensure that possible current transformers are short-circuited before the current connections on the device are opened.

Please ensure that the operating temperature limits are not exceeded when determining
the place of mounting (place of measurement): –10 … +55° C

PM 1000284 000 01 Device handbook SIRAX BT5700 7/31

5. Electrical connections

Ensure under all circumstances that the leads are free of potential when
connecting them!

Please observe that the data on the type plate must be adhered to!

The national provisions have to be observed in the installation and material selection of
electric lines!

PM 1000284 000 01 Device handbook SIRAX BT5700 8/31

All voltage measurement inputs must originate at circuit breakers or fuses rated by 1 Amps. 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.

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

No fuse may be connected upstream of the current measurement inputs!

When using current transformers their secondary connectors must be short-circuited during
installation and before removing the device. Never open the secondary circuit under load.

The connection of the inputs depends on the confi gured system (connection type).

5.4 Power supply

A marked and easily accessible current limiting switch has to be arranged in the vicinity of the
device for turning o the power supply. Fusing should be 10 Amps or less and must be rated for
the available voltage and fault current.

The signal wires (A, B) have to be twisted. GND (G) can be connected via a wire or via the cable screen. 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 daisy chain 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.

6. Commissioning

Before commissioning you have to check if the connection data of the device match the data of
the plant.
If so, you can start to put the device into operation by switching on the power supply and the
measurement inputs.

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

Rt: Termination resistors: 120 Ω each for

long cables (> approx. 10 m)

Rs: Bus supply resistors,
390 Ω each
