3 BASIC SAFETY INSTRUCTIONS

These safety instructions do not make allowance for any contin-

gencies and events which may arise during installation, operation

and maintenance.

Risk of injury from high pressure.

▶Before loosening lines or valves, switch o the pressure and

drain the lines.

Risk of injury due to electric shock.

▶Before reaching into the device or the system, switch o the power

supply and secure to prevent reactivation! Observe the applicable

accident prevention and safety regulations for electrical devices.

Risk of burns or risk of re.

Continuous operation or hot media may result in a hot device

surface.

▶Keep the device away from highly ammable substances and

media and do not touch with bare hands!

▶Do not obstruct heat dissipation required for operation.

Risk of injury due to cold, hot and aggressive media.

Heat sources or temperature uctuations may cause malfunctions

or leaks.

▶Avoid heat sources which may cause the permissible tempera-

ture range to be exceeded.

▶Check the media resistance before use.

english

Danger due to low and high temperatures.

Depending on the media temperature, the device can become

extremely cold or extremely hot.

▶Keep the device away from substances sensitive to cold and

highly ammable substances and do not touch with bare

hands.

Destruction of the coil due to overheating

▶Electrically connect coil with mounted housing only.

▶In the case of alternating voltage, pay attention to movable

core.

▶Check media resistance.

General hazardous situations.

To prevent injuries, ensure that:

▶Do not feed in any aggressive or highly ammable media.

▶Do not make any internal or external changes to the device.

▶Secure the system and device against accidental activation.

▶Installation and maintenance may only be performed by autho-

rised technicians only using the appropriate tools.

▶After an interruption in the power or pneumatic supply, ensure

that the process is restarted in a dened or controlled manner.

▶Do not mechanically load housing.

▶Observe the general rules of technology.

▶Before loosening lines and valves, turn o the pressure and

drain the lines!

Risk of injury due to electric shock.

▶Before reaching into the system, switch o the power supply

and secure to prevent reactivation.

▶Observe the applicable accident prevention and safety regula-

tions for electrical devices.

WARNING!

Risk of injury due to improper installation.

▶Installation may be carried out by authorised technicians only

and with the appropriate tools.

→Screw cable plug tightly onto the coil

(max. 1 Nm).

Only for variant with terminal connection box:

•Connect a maximum of one conductor per terminal point

•The maximum connection cable cross-section is 2.5 mm² / AWG 14

•Remove insulation on the wires to a maximum length of 6 mm

5.3 Rotating the solenoid

WARNING!

Risk of injury due to electric shock.

If there is no protective conductor function between the coil and

body, there is a risk of electric shock.

▶Check the protective conductor function after installing the coil.

Overheating, risk of re.

Connecting the coil without rst installing the valve will lead to

overheating and will destroy the coil.

▶Only connect the coil after the valve has been installed.

The coil can be rotated by 4 x 90°.

→Rotate the solenoid.

→Use a matching open-end wrench to

tighten the nut (max. 5 Nm).

6 MAINTENANCE, TROUBLESHOOTING

WARNING!

Risk of injury due to improper maintenance work.

▶Maintenance may be carried out by authorised technicians only

and with the appropriate tools.
