1 Safety
This document contains important instructions for the use of the product. Always follow all instruc-
tions and operate the product with caution. If you have any questions, please contact Knick
Elektronische Messgeräte GmbH & Co. KG (sometimes hereafter referred to as “Knick”) using the infor-
mation provided on the back page of this document.
The product may not be opened, modified, or independently repaired. Do not use the product if the
housing is damaged. Replace with an equivalent product. Repairs may only be carried out by Knick.
1.1 Intended Use
The transducers in the P45000 product line measure voltages on rail vehicles as well as in rail infra-
structure and industrial systems.
The P45000 may only be mounted on rolling stock in closed electrical operating areas at installation
location 1 according to EN50155 annex C. If the P45000 is mounted on the interior of rail vehicles, it
must be mounted in closed and fireproof control cabinets.
The input may be connected directly to primary circuits (high potential). All definitions and specifica-
tions in the technical data must be observed.
The input signal is received by the P45000, processed, and galvanically isolated from the output and
power supply. The output signal, which is proportional to the input, is galvanically connected to the
power supply.
For further processing, the output signal is fed into a controller, a protection device, an indicator, or a
data acquisition system.
Fields of Application
• Rolling stock
• Railway substations
• High voltage drives
• Industrial plants
• Infrastructure systems
• Power electronics
• Rectifiers and inverters
• Battery backup and emergency power systems
USE CAUTION AT ALL TIMES WHEN INSTALLING, USING, OR OTHERWISE INTERACTING WITH THE PRODUCT.
ANY USE OF THE PRODUCT EXCEPT AS SET FORTH HEREIN IS PROHIBITED, AND MAY RESULT IN SERIOUS IN-
JURY OR DEATH, AS WELL AS DAMAGE TO PROPERTY. THE OPERATING COMPANY SHALL BE SOLELY RE-
SPONSIBLE FOR ANY DAMAGES RESULTING FROM OR ARISING OUT OF AN UNINTENDED USE OF THE PROD-
UCT.
1.2 Personnel Requirements
The operating company shall ensure that any personnel using or otherwise interacting with the prod-
uct is adequately trained and has been properly instructed.
The operating company shall comply and cause its personnel to comply with all applicable laws, regu-
lations, codes, ordinances and relevant industry qualification standards related to product. Failure to
comply with the foregoing shall constitute a violation of operating company’s obligations concerning
the product, including but not limited to an unintended use as described in this document.

1.3 Avoiding Electric Shocks and Fires
Adhere to the specifications of EN50343 when making electrical connections.
Connected tubing at the output and the voltage supply must be rated for the current limit of the pro-
tective device for the circuit.
Protective measures against direct contact: The operating company must take protective measures
against direct contact at the freely accessible screwed contacts. As set out in EN50153, Chapter5, this
can be ensured, for example, by installation in a lockable control cabinet. Other national or applica-
tion-specific regulations must be observed.
Distances to adjacent devices and conductive parts in the vicinity of the device must be dimensioned
and maintained in accordance with the applied standard. Isolation coordination with clearance and
creepage distances (➜Clearance and Creepage Distances, p. 30,
➜Clearance and Creepage Distances, p. 31) and the relevant standards (e.g., EN50124-1) must be car-
ried out, evaluated, and ensured.
If the device is mounted horizontally according to EN50124-1 and with pollution degree PD3A, it may
only be mounted on plastic surfaces with CTI600.

rules and regulations, as well as an internal risk assessment. Despite the foregoing, the product may
among others bear the following risks:
Environmental Influences

2.6 Functional Description
Measuring Functions
The transducer is used for the conditioning, filtering, and galvanic isolation of high voltages. The trans-
ducer transfers analog signals from what is usually a high potential to a near-ground potential in order
to be able to further process the detected signals safely and with low interference.
An analog signal is emitted at the output of the transducer, which is an image of the analog measuring
signal at the input of the transducer. The amplitude of the input voltage may be up to several kilovolts,
depending on the device design. Both unipolar and bipolar input signals can be processed. Either a
unipolar or bipolar current signal is provided at the output of the transducer. The 2-port isolation, i.e.,
the galvanic isolation between input and output/power supply, ensures personal and plant safety as
well as increasing the signal integrity of the measuring device.
Live Zero Function (P45**1K2*** Only)
The products with SIL suitability detect certain internal faults (e.g., undervoltage, transmission failure)
and set the output to a defined value as a fault response. This live zero function facilitates external
monitoring of the output signal. The 10…50mA output signal (live zero) can be used to detect inter-
ruptions or short circuits of the output tubing. When doing so, output currents <9mA are to be inter-
preted as an error.

The push-in terminal is executed as a two-tier terminal. Two internally connected terminals are avail-
able for each electrode. Consequently, the power supply can be looped in from one device to the next.
It should be noted that the output signal is galvanically connected to the power supply in each case.

2.8 Installation
2.8.1 General Installation Instructions
WARNING! Shock potential. Do not install the product live.
WARNING! Risk of electrical flashover. When used in accordance with EN50124-1 and pollution
degree PD3A (P45***K2*1* only), the product may be mounted horizontally only on plastic surfaces
with CTI600.
CAUTION! Safeguards! In the interior of rail vehicles, the transducers must be mounted in closed

3 Operation
3.1 Commissioning
NOTICE! Permanent overdrive can lead to overheating and thus to increased failure rates. Adhere to
the specifications and observe the chapter on dimensioning the load.
The P45000 is configured ex works for the version ordered and has no controls.
3.2 Operation
The high voltage transducer is configured ex works and does not have any operating elements.
3.3 Troubleshooting
Follow the Safety Instructions. ➜Safety, p. 5
Initial troubleshooting steps:
• check that all tubing is properly connected.
• check the power supply.
Malfunction State Possible Cause Remedy
Unexpected measured value. The input signal is not properly con-
nected.
Check if the input signal is actually
present.
Current output overload. Measure the voltage across the cur-
rent output terminal and measure the
output current. Calculate the result-
ing load.➜Output, p. 26
Input is overdriven: The input voltage
is lower than the selected start-of-
scale value or higher than the
selected full scale value. Observe per-
mitted overdrive.
Adjust the range or correct the
overdrive.➜Input, p. 25
Tubing fault between output and
control.
Check the 10…50mA output with an
ammeter to determine if the output
current is <9mA. Signals <9mA are
to be interpreted as an error.
Correct line short-circuits or interrup-
tions at the output
3.4 Maintenance
The devices are maintenance-free. The customer may request that the devices be recalibrated or ad-
justed at the factory. The electronics cannot be repaired, as the devices are potted.
3.5 Return
If required, send the product in a clean condition and securely packed to your local contact.
