1 Safety
This document contains important instructions for the use of the product. Always follow all
instructions 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
information 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 appendix 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, galvanically isolated, and output as a floating,
proportional analog signal.
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
INJURY OR DEATH, AS WELL AS DAMAGE TO PROPERTY. THE OPERATING COMPANY SHALL BE SOLELY
RESPONSIBLE FOR ANY DAMAGES RESULTING FROM OR ARISING OUT OF AN UNINTENDED USE OF THE
PRODUCT.
1.2 Personnel Requirements
The operating company shall ensure that any personnel using or otherwise interacting with the
product 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

1.3 Avoiding Electric Shocks and Fires
Comply with all instructions relating to installation and operation. ➜Installation, p. 13
Adhere to the specifications of EN 50343 when making electrical connections.
Connected cables and lines must be rated for the current limit of the protective device for the circuit at
minimum. At the input this does not apply.
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. 28, ➜Clearance and Creepage Distances, p. 29) and
the relevant standards (e.g., EN50124-1) must be carried out, evaluated, and ensured.
If the device is mounted horizontally according to EN 50124-1 and pollution degree PD3A, then it may
only be mounted on plastic surfaces with CTI600.
1.4 Residual Risks
Note the different levels of functional safety depending on the selected product variant.
The product has been developed and manufactured in accordance with generally accepted safety
rules and regulations, as well as an internal risk assessment. Despite the foregoing, the product may
among others bear the following risks:
Environmental Influences
The effects of moisture, corrosion and ambient temperature as well as high voltages and transient
overvoltages may affect the safe operation of the product. Observe the following instructions:
• Only operate the P45000 in compliance with the stated operating conditions.

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 per-
sonal and plant safety as well as increasing the signal integrity of the measuring device. The enclosure
is made from silicone-free enclosure materials. The isolation characteristics are achieved, for example,
by potting with a silicone-free polyurethane casting resin.
Internal device diagnostics
The analog output signal (measuring signal) is set to a defined value in the event of an error.
➜Specifications, p. 23
Live zero function
The live zero function facilitates monitoring of the output signal. The 10…50mA output signal (live
zero) can be used to detect interruptions, or short circuits of the output cables. When doing so, output
currents <9mA are to be interpreted as an error.

2Negative supply voltage / power supply 4Positive supply voltage / power supply
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. Install the product with the power off.
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.
The P45000 can be mounted in any installation position:
• vertically or horizontally on flat surfaces (with screws).
• on a 35-mm DIN rail (without using a DIN rail bus connector)

3 Operation
3.1 Commissioning
The P45000 is configured ex works for the version ordered. During commissioning, no settings can, or
need to be changed.
3.2 Operation
The high voltage transducer is configured ex works and does not have any operating elements.
3.3 Troubleshooting
First steps for troubleshooting:
• Check that all cables are properly connected.
• Check the power supply.
Comply with the safety instructions. ➜Safety, p. 5
Malfunction state Possible causes Remedy
Current does not correspond
to the expected value
Check the input signal. Check if the input signal is actually present.
Check the output signal. Measure the current output, e.g., by connecting a
multimeter to the output terminals.
Check if the current output has
been overloaded.
Measure the voltage across the current output ter-
minal and measure the output current. Calculate the
resulting load. The load must not exceed 200Ω for
currents up to ±50mA or 133Ω for currents up to
±75mA.
Check for overdrive of the input
signal.
Negative overdrive results in a large negative signal.
Positive overdrive results in a large positive signal.
Check the output. At the 10…50mA output, check if the output cur-
rent is <9mA. Signals <9mA are to be interpreted
as an error. The cause may be an interrupted output,
for example.
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.
➜knick.de
3.6 Disposal
The local codes and regulations must be observed when disposing of the product.
