1. APPLICATION
The P11P 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 25 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 35 mm DIN rail (DIN EN 50 022-35).
P11P - transducer destined for active power measurement
in a single-phase network.
P13P - transducer destined for active power measurement
in a symmetrically loaded 3-phase 3-wire network.
P13B - transducer destined for reactive power measurement
in a symmetrically loaded 3-phase 3-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 61010-1 standard.

Remarks concerning the operator safety:
P11P, P13P and P13B transducers are destined to be mounted on
35 mm DIN rails. In the range of operational safety they are in
conformity with the EN 61010-1standard requirements.
lThe installation and transducer connection should be
operated by a qualified personnel.
lOne must take into consideration all accessible protection
requirements.
lBefore switching the instrument on, one must check the
correctness of the network lead connection.
lIn case of the protection terminal connection with a separate
lead one must remember to connect it before the connection
of network leads.
lDo not connect the instrument to the network through an
auto-transformer.
lBefore taking the transducer housing out, one must turn
the supply off.
lThe removal of the transducer housing during the guarantee
contract period may cause its cancellation. The programmer
connector is destined only for the PD11 programmer
connection. After the transducer programming, one should
put the hole plug of the programmer connector.

5. INSTALLATION
5.1 Fixing
P11P, P13P or P13B transducers are designed to be installed on a
35 mm DIN rail acc. DIN EN 50 022-35. On the external side of the
transducer there are screw or self-locking terminal strips enabling
the connection of 2.5 mm2external leads (supply and output) and
up to 1.5 mm2leads (input).
