1. Introduction 1.1 Purpose of this document This document describes the universal measurement device SIRAX BT5100. It is intended to be used by: • Installation personnel and commissioning engineers • Service and maintenance personnel • Planners Scope This handbook is valid for all hardware versions of the BT5100. Some of the functions described in this document are available only, if the necessary optional components are included in the device. Required knowledge A general knowledge in the field of electrical engineering is required. For assembly and installation of the device knowledge of applicable...

3. Device overview The SIRAX BT5100 is a top-hat rail mounted Transducer and used to measure and convert AC Voltage input into an proportional DC current or voltage output signal. Input Voltage and Output Voltage/Current is displayed on LCD and indicated by LED’s. 4. Mechanical mounting The SIRAX BT5100 is designed for panel mounting. Please ensure that the operating temperature limits are not exceeded when determining the place of mounting (place of measurement): 0 … +45 °C 4.1 Mounting Dimensional drawing BT5100: See section 10 Any mounting position is possible. Device may be clipped onto a...

A 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! 5.2 Cross sections and tightening torques Terminals 1 ... 8 Single wire: < 4,0mm2 or multiwire with end splices: 2 x 2,5mm2 Torque: 0.5 ... 0.6Nm rsp. 4.42 ... 5.31 Ibf in Terminal A, B, G Single wire: < 1,5mm2 or multiwire with end splices: 2 x 0,5mm2 Torque: max. 0.5 Nm rsp. 4.42 lbf in A All voltage measurement inputs must originate...

5.5 Connection Diagram Connection Via the optional Modbus interface measurement data may be provided for a superior system. 1) One ground connection only. This is possibly made within the master (PC). Rt: Termination resistors: 120 0 each for Rs: Bus supply resistors, long cables (> approx. 10 m) 390 0 each The signal wires (A, B) have to be twisted. G can be connected via a wire or via the cable screen. In disturbed environments shielded cables must be used. To avoid the possibility of loop currents, an Earth connection should be made at one point on the bus. Supply resistors (Rs) have to...
