Procedure after the
expiration of the maximum
storage time of 12 months

chapter 14.2 "List of addresses".
7 Assembly
High pressure!
Risk of injury due to parts shooting out during works at hydraulic accumulators
which have not been unloaded.
Carry out any work at the safety valve only after the system has been
f
depressurized.
Unload accumulators which may have been mounted at the system.
f
Check the system with test pressure according to ISO 4413.
f
Assembly and commissioning may only be carried out by specialists.
f
Leaking hydraulic fluid!
Slip hazard!
Do not remove the protective covers until assembly.
f
Immediately remove leaking oil.
f
Insufficient assembly space!
Danger of jamming and bruising! Danger of component damage! Insufficient
installation space may lead to jamming or abrasions in case of actuation or
adjustment works at the safety valve. Components cannot be properly mounted or
might be damaged.
Make sure that the assembly space is sufficient.
f
Penetrating humidity!
The housing of the valve electronics is closed. However, according to the applicable
protection class, fluids may enter and lead to faults and short-circuit. Safe function
of the safety valve is therefore no longer ensured.
When working at the safety valve, always ensure that no fluid can enter the
f
electronics.
Major potential differences!
Danger of destruction of the valve electronics by connecting or disconnecting plug-
in connectors under voltage.
De-energize the relevant system part before assembling the device or when
f
connecting and disconnecting connectors.
