2 Safety instructions
2.1 General information on this chapter
The hydraulic power unit was designed and manufactured according to the generally
accepted code of practice. However, there is still the danger of personal injury and
damage to property if you do not observe this chapter and the safety instructions in
this documentation.
▶ Read this documentation completely and thoroughly before working with the
hydraulic power unit.
▶ Keep this documentation in a location where it is accessible to all users at all
times.
▶ Always include the required documentation when you pass the hydraulic power
unit on to third parties.
Due to the interaction between the hydraulic power unit and the complete machine,
the installation of the hydraulic power unit into the
overall machinery/system will result in additional potential hazards. This applies
in particular to the influence of hydraulic and electric controls on hydraulic drives
generating mechanical movements. It is therefore essential for the manufacturer of
the overall machinery/system to have undertaken an independent risk assessment.
Furthermore, the manufacturer must on this basis have prepared operating
instructions for the complete machinery.
These operating instructions do not serve as replacement of the operating
instructions of the overall machinery/system.
2.2 Intended use
The hydraulic power unit is a hydraulic system component.
You may use the product as follows:
The hydraulic power unit constitutes partly completed machinery in the sense of the
EC Machinery Directive 2006/42/EC and respectively not usable.
The hydraulic power unit is exclusively intended for integration into a machine or
system or for assembly with other components to form a machine or a system. The
product may be commissioned only if it has been integrated into the machine or
system for which it is designed and if the machine or system fully complies with the
requirements of the EC Machinery Directive.
The hydraulic power unit serves for controlled or regulated generation of hydraulic
flow and hydraulic pressure.
The hydraulic power unit is not considered to be a safety component in the sense
of the EC Machinery Directive 2006/42/EC.
The hydraulic power unit must not exceed the operating conditions and
performance limits specified in the technical data.

Safety instructions 11/84
CytroPac, RE 51055-B/06.17, Bosch Rexroth AG
The hydraulic power unit is technical equipment exclusively intended for professional
and not for private use.
Intended use also includes having read and understood these documentation
completely, especially chapter 2 "Safety instructions" and chapter 3 "General
information on damage to property and damage to product".
2.3 Improper use
Any use deviating from the intended use is improper and thus not admissible.
Bosch Rexroth AG does not assume any liability for damage caused by improper use.
The user assumes all risks involved with improper use.
The hydraulic power unit is not suitable for operation in explosive environments.
Improper use of the hydraulic power unit includes:
▶ Non-compliance with the technical data, operating conditions, performance limits
and environmental conditions specified in chapter 16.
▶ Operation of the hydraulic power unit with hydraulic fluid not complying with the
specifications in chapter 16.
▶ Use of spare parts that are not approved by the manufacturer.
▶ Mechanical modification of the hydraulic power unit.
▶ Welding or soldering works at the hydraulic power unit.
2.4 Qualification of personnel
The activities described in this documentation require basic knowledge of
mechanics, electrics and hydraulics as well as knowledge of the appropriate
technical terms. For transporting and handling the hydraulic power unit, additional
knowledge of how to handle lifting gear and the necessary attachment devices is
required. In order to ensure safe use, these activities may only be carried out by a
corresponding expert or an instructed person under the direction and supervision of
an expert.
Experts are those who are able to recognize potential dangers and apply the
appropriate safety measures due to their professional training, knowledge and
experience, as well as their understanding of the relevant conditions pertaining
to the work to be undertaken. An expert must observe the relevant specific
professional rules and have the necessary hydraulic and electrical expert knowledge.
Bosch Rexroth offers measures supporting training in specific fields. An overview

20/84 Product information
Bosch Rexroth AG, CytroPac, RE 51055-B/06.17
5 Product information
5.1 Performance description
The CytroPac is a compact drive system (smaller tank, cooling system) for hydraulic
machines and particularly machine tools and assembly lines under limited space
conditions.
The CytroPac is particularly quiet due to plastic enclosure of all noise sources.
The frequency converter of the variable speed pump drive ensures dynamic
adjustment of the power/speed and the flow to current requirements to reduce the
operating costs.
In "Basic" configuration, the filling level, temperature and filter contamination
sensors must be wired by the customer for evaluation via the customer-side machine
control system.
In "Advanced" configuration, the frequency converter serves as sensor node and
bundles all measured values of filling level, temperature and filter contamination
sensors and forwards these values via a mating connector to the customer-side
machine control system. The status of the hydraulic power unit is also indicated via
the integrated LED strip.
For information on the meaning of the LED signals, refer to fig. 3 "Name plate"
and chapter 10.3 "Warning devices".
In "Premium" configuration, the frequency converter serves as sensor node and
bundles all measured values of filling level, temperature and filter contamination
sensors and forwards these values via a multi-Ethernet interface, e.g. Sercos or
PROFINET, to the machine control system. This ensures reading of all parameters
required for condition monitoring. CytroPac enables easy integration in Industry
4.0 applications. The status of the hydraulic power unit is also indicated via the
integrated LED strip.
For information on the meaning of the LED signals, refer to fig. 3 "Name plate"
and chapter 10.3 "Warning devices".
For an overview of components of the various configurations, refer to data sheet
51055 section "Selection of sensors and interfaces", see chapter 1.2 "Required
and amending documentation".
