Hydraulic lines and hoses installed under tension stress!
Damage to the manifold/module! Lines and hoses installed under tension stress
create additional mechanical forces during operation, which reduces the life cycle
of the manifold/module and the entire system.
▶
Assemble lines and hoses without stress.
7.5.1 Mechanically assembling the manifold/module
Completely fasten the manifold/module at the provided mounting bores and tighten
the screws applying the tightening torque specified in the installation drawing.
7.5.2 Hydraulically connecting the manifold/module
1.
Depressurize the relevant system part.
2.
Establish all connections observing the hydraulic circuit diagrams of the system.
3.
Make sure that pipes and/or hoses are connected to all ports and/or that the
ports are closed with plug screws.
4.
Carry out a special check to make sure that the cap nuts and flanges are correctly
tightened at the pipe fittings and flanges.
5.
Make sure that all pipes and hose lines and every combination of connection
pieces, couplings or connection points with hoses or pipes are checked for their
operational safety by a person with appropriate knowledge and experience.
with manifolds/modules with electric components:
Connecting the power supply
7.5.3
High electrical voltage!
With manifold blocks/modules with installation or attachment components with
a supply voltage > 50 VDC or 75 VAC, touching an electric part at the device may
lead to a fatal electric shock.
▶
Manifolds/modules may only be electrically connected by or under the supervi-
sion of a specialized electrician.
▶
Use suitable plug-in connectors and cables.
▶
Switch off the voltage supply before all maintenance, repair or installation works
and secure it against restarting.
▶
Provide for proper, safe PE connection.
▶
Only use power supply units with safe voltage separation. Safe separation can
for example be achieved by means of isolation transformers, safe optocouplers
or mains-free battery operation.
▶
Apart from that, always observe the country-specific provisions.
