Installation Conditions; Assembling The Cylinder - Emerson AVENTICS Operating Instructions Manual

7 Assembly
Danger of explosion through overheating!
The cylinder generates heat during operation. Incorrect
installation can cause the cylinder to overheat.
O
Ensure sufficient distance to adjacent components to permit
adequate air circulation around the cylinder.
O
Shield the cylinder if it is installed near heat sources.
Danger of explosion if not grounded!
Compensation and residual currents could increase the
temperature of the components and possibly generate sparks.
O
Ground the housing and the piston rod so they are
electroconductive with the system.
O
Ground the system in accordance with applicable
regulations.
Danger of explosion due to impermissible tubing!
Large tubing diameters increase the risk of an electrostatic
charge on the tubing surface. Electrostatic discharge can lead to
explosions.
O
Only use tubing with the following external diameters to
connect the cylinders:
– Cylinder Ø up to 25 mm: max. 6 mm
– Cylinder Ø 32 mm or above: any
Long tubing often overheats during operation. Overheated
tubing can lead to explosions.
O
Use the following tubing lengths:
– Cylinder Ø up to 25 mm: max. 5 m,
– Cylinder Ø 32 mm or above: max. 10 m.
Dust clouds can lead to explosions.
O
Make sure that the compressed air and exhaust are either
evacuated from the dust protection area through tubing
lines or that the exhaust lines are mounted to permit the
continuous controlled exit of penetrating dust.
Danger of explosion due to circulating currents!
Stray magnetic fields may cause circulating currents, e.g. near
electrical drives with asymmetrical loads, during arc welding, if
the ground is conducted via the system and not via a 0 V line, or
if there is cathodic corrosion protection.
O
Make sure that there is protection against the possible
effects of circulating currents, e.g. by grounding the
cylinder.
DANGER
DANGER
Open pneumatic connections!
Contamination of the cylinder interior!
O
Only remove the blanking plugs just before connecting the
tubing.
Incorrect cylinder mounting!
Cylinder damage!
O
Make sure that the cylinder and accessory parts are
properly installed.
O
Observe the maximum tightening torque values and check
that all screws and bolts are properly tightened.

Installation conditions

The cylinder has a lifetime lubrication.
O
The preferred medium is oil-free compressed air.
Compressed air quality: see "12 Technical Data".

Assembling the cylinder

1. Make sure that all relevant system parts are not under voltage
or pressure before installing the cylinder. Protect the system
against being switched on.
Depending on your configuration, you can mount the product in
different ways. The delivery contents only include the mounting
you selected in the configurator.
O
You can find the exact dimensions of the mountings for your
cylinder in the online catalog from AVENTICS.
O
Install the cylinder in your system so the pneumatic
connections and, if present, throttle screws for the cushioning
are always accessible.
2. Fix the cylinder on the bracket in your system part so that it is
not under tension. Observe the maximum permissible
tightening torque values listed in the online catalog from
AVENTICS. General technical standards apply if no information
is given or if you use your own mounting materials.
3. Remove the blanking plugs at the pneumatic connections.
4. Make the pneumatic connections for the cylinder. You can find
the pneumatic connection technology for cylinder tubing in the
online catalog.
5. Fasten the useful load to the piston rod. Depending on the
configuration, you can fix the useful load to the internal or
external thread. Observe the permissible piston forces.
You can find the maximum possible piston forces in the online
catalog from AVENTICS.
On double-acting cylinders, the effective piston surface
and piston force are lower during retraction than
extension due to the cylinder piston rod. This does not
apply to cylinders with a through piston rod.
