    Meter overall dimensions: 96 93 mm (with terminals). The meter casing is made of plastics. Fig. 1 View of the N30P digital meter 2. METER SET The set is composed of: - N30P meter ......... 1 pc - User’s manual ........1 pc - Guarantee card ........

  • Page 7: Basic Requirements, Operational Safety

    · The programming of N30P meter parameters must be carried out after disconnecting measuring circuits · Before switching the meter on, one must check the correctness of connections to the network.

  • Page 8: Installation

    4. INSTALLATION The meter has separable strips with screw terminals which enable the connection of external wires of 2.5 mm cross-section. In execution for current measurement, the plug enables a permanent fixing to the so- cket by means of screws. The meter is adapted to be mounted in a panel by means of clamps, +0.6 +0.6...

  • Page 26: Rs-485 Interface

    6. INTERFACE RS-485 N30P programmable digital meters have serial links in RS-485 standar- ds for the communication in computer systems and with other devices fulfilling Master function. An asynchronous communication character protocol MODBUS has been implemented on the serial link. The trans- mission protocol describes ways of information interchange between devices through the serial link.
