1. APPLICATION
The P20Z transducer is destined for a continuous conversion of the
RMS current or ac voltage without a constant component into a con-
stant-current or constant-voltage standard signal.
The transducer output signal is galvanicaly isolated from the input sig-
nal and supply. The transducer housing is made of a plastic. On the
transducer outside, there are inseparable screw or socket-plug termi-
nal strips.
2. TRANSDUCER SET
The set of the P20 transducer is composed of:
1. P20Z transducer 1 pc.
When unpacking the transducer, please check whether the type
and execution code on the data plate correspond to the order.
3. BASIC REQUIREMENTS and OPERATIO-
NAL SAFETY
In the safety service scope, the transducer meets the requirements of
the EN 61010-1 standard.
Observations concerning the operational safety
lAll operations concerning transport, installation, and commissioning
as well as maintenance, must be carried out by qualified, skilled
personnel, and national regulations for the prevention of accidents
must be observed.

6
lBefore switching the transducer on, one must check the correctness
of connection to the network.
lDo not connect the transducer to the network through an
autotransformer.
lBefore removing the transducer housing, one must switch the
supply off and disconnect measuring circuits.
lThe removal of the meter housing during the guarantee contract
period may cause its cancellation.
lThe P20Z transducer is destined to be installed and used
in industrial electromagnetic environment conditions.
lOne must remember that in the building installation a switch or a
circuit-breaker should be installed. This switch should be located
near the device, easy accessible by the operator, and suitably
marked.

7. MAINTENANCE and GUARANTEE
The P20Z transducer does not require any periodical maintenance.
In case of some incorrect operations:
After the dispatch date and in the period stated in the guarantee card:
One should return the instrument to the Manufacturer’s Quality In-
spection Dept. If the instrument has been used in compliance with the
instructions, we warrant to repair it free of charge.The disassembling
of the housing causes the cancellation of the granted guarantee.
