  • Page 1 UPM307 UNIVERSAL POWER METER USER MANUAL 1. INTRODUCTION This manual provides information on the installation, configuration and use of the main instrument functions. The manual is not intended for general use, but for qualified technicians. This term indicates a professional and skilled technician, authorised to act in accordance with the safety standards relating to the dangers posed by electric current.

  • Page 2: Graphic Symbols

    The basic instrument can be customized with some options to fit to the specific application. The UPM307 is a compact, cost effective meter operating both as a stand-alone device or as part of a more extensive energy monitoring and management network.

  • Page 3: Installation

    5. INSTALLATION NOTE. The equipment complies with the 89/366/EEC, 73/23/EEC standards and following amendments. However, if not properly installed, it may generate a magnetic field and radio interference. This is why compliance with EMC standards on electromagnetic compatibility is essential. 5.1 ENVIRONMENTAL REqUIREMENTS The environment in which the instrument is installed must satisfy the following features: •...

    6. SAFETY MEASURES DANGER! This warning means that a voltage exceeding 1kV (even if for short periods) may be present on the terminals. WARNING! Electrical instrument connections must be carried out only by skilled technicans who are aware of the risks involved to the presence of voltage. Before connecting, check the following: 1.

  • Page 5: Profibus Version

    PROFIBUS VERSION ETHERNET VERSION The connections are made on the back side of the instrument according to the following order. 1. Digital outputs. See section 7.5 2. Communication port (optional). See section 7.1 3. Power supply. See section 7.7 4. Current inputs. See section 7.6 5.
  • Page 6 7.1.2 RS 485 The easiest and cheapest way to connect different measuring devices in a network is the RS485 serial line. The RS485 standard interface allows a multi-point connection. Between PC and the network, it is required a Serial RS232 to RS485 Converter. If more than 32 instruments are to be connected, insert a signal repeater. Each repeater can manage up to 32 instruments.
  • Page 7 7.3 RS485 PROFIBUS COMMUNICATION PORT (optional) The PROFIBUS interface allows a point to point connection: i.e. instrument to PC or other device. For the connection use a STD cable for PROFIBUS connection with a 9-pole male connector on the device side. If the standard cable for PROFIBUS is not available, produce one according to the scheme in the picture.
  • Page 8 7.4 ETHERNET COMMUNICATION PORT (optional) The ETHERNET interface allows a connection between the instrument and an ETHERNET network. For the connection use an HUB or a Switch. If the instrument is set on STANDARD protocol and it is connected to the network, all instrument measurements can be displayed remotely on a PC by typing the IP address of the instrument ETHERNET interface in the web address field.
