About this manual
The purpose of this user manual is to familiarize you with VBO3 and to show you how to use it safely,
properly, and efficiently. Following the instructions in this user manual will help you to prevent danger,
repair costs, and possible down time due to incorrect operation, and it will help you to maintain the
reliability and life of VBO3.
This manual is to be supplemented by existing national safety standards for accident prevention and
environmental protection.
This manual shall always be available at the site where VBO3 is used. It shall be read and observed
by all personnel operating VBO3. Reading the user manual of VBO3 alone does not release you from
the duty of complying with all safety regulations relevant and applicable to working on systems in any
power distribution network.
In addition to the user manual and the applicable safety regulations in the country and at the site of
operation, the usual technical procedures for safe and competent work shall be heeded.
Keep this manual during the entire service life of the product and always have it available for
reference.
This user manual describes the VBO3 hardware, its usage and wiring. In order to get familiar
with CMC test sets, please refer to the corresponding user documentation.

1 Introduction
1.1 Scope of delivery
The following accessories are part of the VBO3 standard delivery but can also be ordered separately:
Accessory Quantity Order number
Connection cable VBO3 to CMC, 4-pole, 1 m length 2 VEHK0053
Connection cable VBO3 to test object, 4-pole, 3 m length 1 VEHK0054
Flexible jumpers 4 VEHZ0009
Module bag 1 VEHP0031
Before operating VBO3 for the first time, use the shipping documents to verify that all accessories are
available.
1.2 Designated use
VBO3 is a voltage transformer and used as an accessory for OMICRON's CMC test sets. The device
is intended for use with CMC test sets only. VBO3 transforms a CMC's output voltages of 0 ... 300 V to
0 ... 600 V.
Therefore, you can use CMC test sets for testing the V>> stage of LOM protection at wind power
stations. Their threshold is at least 460 V (nominal voltage in wind power stations is 690 V L-L
(398.37 V L-E)). You can also test other renewable energy systems such as biogas, photovoltaic,
small hydroelectric power as well as combined heat and power plants.
Furthermore, you can test industrial networks with voltage levels > 300 V.
Disclaimer
The advisory procedures and information contained within this user manual have been compiled as a
guide to the safe and effective operation of VBO3. It has been prepared in conjunction with application
engineers and the collective experience of the manufacturer.
The in-service conditions for the use of VBO3 may vary between customers and end-users.
Consequently, this user manual is offered as a guide only. It shall be used in conjunction with the
customer’s own safety procedures, maintenance program, engineering judgment, and training
qualifications.
If VBO3 is used in a different manner than described in this user manual, the protection provided by
VBO3 may be impaired, and this may result in damage to property or persons.
1.3 Declaration of conformity (EU)
The equipment adheres to the guidelines of the council of the European Community for meeting the
requirements of the member states regarding the low voltage directive (LVD) and the RoHS directive.

2.3 Safe operation procedures
► Before connecting and disconnecting test objects, verify that all outputs have been turned off and
the installation is dead. Never connect or disconnect a test object while the outputs are active.
► When disconnecting power supply cables or test leads, always start from the device feeding the
power or signal.
► Do not operate VBO3 when explosive gas or vapors are present.
► Only work in well lit areas. If there is not enough daylight, use a strong light to make sure that you
see everything and so ensure your safety.
► Keep your work area clean to avoid accidents.
► If VBO3 seems to be functioning improperly or has visible damages, please contact the OMICRON
Technical Support (→ page 23).
