2 Safety instructions
2�1 About this chapter
The press module type IH04E 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 press module type IH04E.
▶ 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 press
module type IH04E on to third parties.
▶ Additionally, please observe the safety instructions for the overall
machine/system.
The safety instructions in these instructions only refer to the scope of delivery.
Due to the interaction between the press module IH04E and the overall
machine/system, the installation of the press module IH04E into the machine
involves additional hazards. This applies in particular to the influence of
hydraulic and electric controls on hydraulic drives which generate 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 overall machine/system.
These assembly instructions do not serve as replacement of the operating
instructions of the overall machine/system.
2�2 Intended use
The product is ahydraulic control block. It is intended for use in industrial
machines only. You may use the product as follows:
• for the control of alower piston die cushion in hydraulic or mechanical presses
according to ENISO16092
• in accordance with the application and environmental conditions according
to the datasheet63129
• in accordance with the specified performance limits according to the
system-specific circuit diagram and according to datasheet63129
• using in the original state (apart from system-specific settings) and/or
without damage
The press module type IH04E is technical equipment and not intended for
private use.

free of dust and foreign substances in order to prevent foreign particles
(e.g.welding beads or metal chips) from getting into the hydraulic lines and
causing wear or malfunctions at the press module type IH04E.
▶ Make sure that all connections, hydraulic lines and attachment parts
(e.g.valves) are clean and free of chips.
▶ For removing lubricants or any other contamination, use industrial residue-free
wipes.
▶ No contamination must enter when closing the connections.
▶ Before commissioning, ensure that all hydraulic connections are tight and
that all seals and caps of the plug-in connections are correctly installed and
undamaged in order to prevent fluids and foreign particles from penetrating
the press module type IH04E.
Mixing hydraulic fluids!
Damage to property!
▶ Generally avoid any mixing of hydraulic fluids of different manufacturers
and/or of different types of the same manufacturer.
▶ Check the compatibility of the various hydraulic fluids and their compatibility
with the components and seals. Mixing of hydraulic fluids may occur for
example due to hydraulic fluid residues in acomponent.

NOTICE
Improper cleaning!
Damage to property!
▶ Cover all openings with the appropriate protective fittings / plugs / protective
caps in order to prevent cleaning agents from penetrating the system.
▶ Check that all seals and electric plug-in connectors are firmly fitted to prevent
the penetration of cleaning agents.
▶ Do not use aggressive and/or easily inflammable cleaning agents for cleaning.
Clean the product using asuitable cleaning liquid and residue-free
industrial wipes.
Leaking or spilled hydraulic fluid!
Environmental pollution and contamination of the ground water!
▶ Immediately remedy possible leakage.
▶ If hydraulic fluid is spilled, use an oil binding agent.
▶ Observe the information in the safety datasheetof the hydraulic fluid and
the system manufacturer's provisions.
Environmental pollution caused by incorrect disposal!
Environmental pollution! Damage to property!
▶ Dispose of the press module type IH04E, the hydraulic fluid and the packaging
in accordance with the applicable national regulations in your country.
▶ Dispose of the hydraulic fluid according to the applicable safety datasheetof
the hydraulic fluid.
ONLY FOR ELECTRIC COMPONENTS!
Uncontrolled disconnection and connection of plug-in connectors!
Damage to property!
▶ Before installation works, separate the device from the mains or from
the voltage source or de-energize it.
▶ Do not plug in or pull off the electric plug-in connector as long as the
voltage supply is activated.
