• Do not commission the product until you can be sure that the end product
(for example a machine/system) where the Rexroth products are installed
complies with the country-specific provisions, safety regulations and standards
of the application.
• Never remove or damage lead seals that have been fitted at the factory.
• Make sure that all safety equipment included in the scope of delivery is present,

2.5.1 General safety instructions for press modules
Pay particular attention to the hazards specified in par. 4 of EN ISO 16092 and
EN 289 standards, such as:
• crushing and shearing between moving parts, such as tools, press slides,
ejectors, or components attached to the lower die to perform special functions
• danger of entrapment (hazard due to being caught) in moving parts of the machine,
separating protective devices, motor and drive machinery, mechanical handling
equipment
• ejection of machine components
Pay attention to the main hazard zones specified in par. 4 of EN ISO 16092 and
EN 289 standards, such as:
• die area with moving parts
• mechanical handling devices
The installation of the press module is only admissible if a leakage speed of 5mm/s
is not exceeded when opening the measuring port on the load-supporting side.
For hydraulic presses according to EN ISO 16092-3 and use of a PLC for valve
monitoring, the PLC must meet the specification profile (such as SRP/CS)
according to EN ISO 13849-1 PL "e" (category 4).
For maintenance and repair, the user must additionally ensure a mechanical restraint
device between the tools, see EN ISO 16092, 5.3.6 and/or EN 289, 5.4.1.1.3.
For hydraulic presses according to EN289 with a depth of the clamping plate
greater than 800 mm and stroke greater than 500 mm, a mechanical restraint device
according to EN 289, 5.4.1.1.3. is required.
