2 Safety instructions

2.1 About this chapter

The product has been manufactured according to the generally accepted rules of

current technology. There is, however, still a risk of personal injury or damage to

equipment if you do not observe this Chapter and the safety instructions contained

in this documentation.

▶ Read these instructions completely and thoroughly before working with the

product.

▶ Keep this documentation in a location where it is accessible to all users at all

times.

▶ Always pass the product together with the required documentation to third

parties.

2.2

Intended use

The product is an electrical component.

You may use the product as follows:

tfor realizing all the required electrical functions for the HS4 or EO4 control

with electrohydraulic swivel angle and pressure control as well as for the power

limitation of variable displacement axial piston pumps.

The product is intended exclusively for professional use and not for private usage.

Operation according to the intended use also implies that you have read and

understood this documentation completely, especially Chapter 2 “Safety

instructions“.

2.3

Improper use

Any use other than described in the section “Intended use” is considered as improper

and is therefore not permitted

For damage resulting from improper use, Bosch Rexroth AG will not bear liability.

The risks arising from improper use lie exclusively with the user.

The following, foreseeable misuse is also not in accordance with the intended use:

tUse of the control electronics for activating components or devices other than the

above-mentioned pump controls;

tif you operate the control electronics beyond the given performance limits and

operating conditions, especially the prescribed ambient conditions.

2.4

Personnel qualiﬁcations

The activities described in this documentation require basic knowledge of electrics

and hydraulics as well as knowledge of the associated technical terms. To ensure

safe usage, these activities may therefore only be carried out by qualiﬁed personnel

to them, recognize potential hazards and institute appropriate safety measures

. Qualiﬁed

personnel must observe relevant specialist rules and have the required expertise.

With regard to hydraulic products, specialist knowledge means, for example:

tAbility to read and completely understand hydraulic circuit diagrams,

tcomplete understanding in particular of interrelationships with regard to safety

equipment and

tknowledge of the function and structure of hydraulic components.

Bosch Rexroth oﬀers qualifying training courses in speciﬁc ﬁelds. You can ﬁnd an

overview of training contents on the Internet at:

operated.

tUse Rexroth products only in technically perfect condition.

tObserve all notes given on the product.

tPersons who install, commission, operate, demount or maintain Rexroth products

must not consume any alcohol, drugs or pharmaceuticals that may aﬀect their

ability to respond.

tOnly use accessory and spare parts approved by the manufacturer in order to rule

out personnel hazards arising from unsuitable spare parts.

tAdhere to the technical data and ambient conditions provided in the product

documentation.

tIf unsuitable products are installed or used in safety-relevant applications,

unintended operational states can occur in these applications, which can cause

personal injury and damage to property. Therefore, use the product only in

safety-relevant applications such as in explosion protection areas or in safety-

related parts of a control (functional safety), if this use is expressly speciﬁed and

permitted in the documentation.

Bosch Rexroth AG, VT-VPCD, RE 30028-B/09.13

2.6 Product-speciﬁc safety instructions

WARNING

Hazardous movement!

Risk of injury due to incorrect activation of the pump control by the control

electronics and resulting unforeseeable machine movements.

▶ Only operate the control electronics in conjunction with the pump control

speciﬁed in the type code.

▶ If persons have to enter the hazard zone while the control is active, provide

superordinate monitoring functions or measures for personal safety at system

level. The plant manufacturer/user must rate and dimension these measures on

the basis of a risk and failure analysis according to the speciﬁc situation on site.

The safety regulations valid for the system must be taken into account for this.

The control electronics emits interference to other electronics within the permitted

limit values. This can cause malfunction in the control process.

▶ Only use electronics below the EMC limit values or provide appropriate

shielding.

The control electronics VT-VPCD responds to electromagnetic interference from

non-shielded, improperly installed or wrongly connected cables. If the limit values

given in the data sheet are exceeded, malfunction or uncontrolled movements are

possible.

▶ Adhere to the limit values speciﬁed in the data sheet, use only electronics below

the EMC limit values or provide proper shielding.

Electrostatic processes, an inadequate grounding concept or missing equipotential

bonding can lead to damage to the electronics and hence cause malfunction or

uncontrolled movements of the machine.

▶ Ensure proper grounding and provide equipotential bonding.

Using the product outside the given IP protection class can result in short-circuit

and malfunction and can therefore cause uncontrolled machine movements.

▶ Only use the product within the IP protection class and under ambient

conditions as given in the data sheet.

The control electronics VT-VPCD itself does not include safety functions for

personal safety and is therefore no safety-relevant component. The control

electronics merely serves to generate electrical functions of the pump controls.

▶ Provide safety functions for personal safety separately.

▶ Avoid contact with salt-containing environments and adhere to the ambient

conditions speciﬁed in the data sheet.

High pressure!

Risk of injury!

▶ Depressurize the relevant system section before carrying out any work on the

control electronics.
