3 . APPLICATION The PP transducer is destined for the conversion of active or reactive a.c. power into a d.c. current or d.c. voltage standard signal. The input, output and supply circuits are galvanically isolated (transformer separation) The conversion frequency range enables the correct measurement of power when currents and voltages are distorted (up to 2 th harmonic). The pulse feeder ensures the operation in a width range of values and frequency of the supply voltage. The measurement is realised through the analogue multiplier function with the pulse modulation (TDM). These transducers are destined to operate in industrial conditions and can be mounted in optional position. Transducer housings are made of a self-extinguishing plastic and are adapted to be fixed on mm DIN rail (DIN EN 022-). PP - transducer destined for active power measurement in a single-phase network. PP - transducer destined for active power measurement in a symmetrically loaded -phase -wire network. PB - transducer destined for reactive power measurement in a symmetrically loaded -phase -wire network. 2. BASIC REQUIREMENTS, OPERATIONAL SAFETY Symbols located in this service manual mean: Especially important, one must acquaint with this before connecting the transducer. The non-observance of notices! marked by these symbols can occasion the damage of the transducer. One must take note of this when the transducer is working? inconsistently to the expectations. In the security scope the transducer meets the requirements of the EN - standard.

4 Remarks concerning the operator safety:! PP, PP and PB transducers are destined to be mounted on mm DIN rails. In the range of operational safety they are in conformity with the EN -standard requirements. l The installation and transducer connection should be operated by a qualified personnel. l One must take into consideration all accessible protection requirements. l Before switching the instrument on, one must check the correctness of the network lead connection. l In case of the protection terminal connection with a separate lead one must remember to connect it before the connection of network leads. l Do not connect the instrument to the network through an auto-transformer. l Before taking the transducer housing out, one must turn the supply off. l The removal of the transducer housing during the guarantee contract period may cause its cancellation. The programmer connector is destined only for the PD programmer connection. After the transducer programming, one should put the hole plug of the programmer connector..
