2 INTENDED USE
Incorrect use of the solenoid valve can be dangerous to people, nearby equipment and the environment.
The device type6213 EV/ 6281EV isdesignedtocontrol,shutoff and meter neutral media up to a viscosity of 21 mm2/s.
Provided the cable plug is connected and installed correctly, e.g.
Bürkert Type 2508, the device satisfies protection class IP65 in accordance with DIN EN 60529 / IEC 60529.
Use according to the permitted data, operating conditions and conditions of use specified in the contract documents and operating instructions.
In the case of explosion-proof devices (see rating plate or additional plate) also follow the operating instructions for the coil / pilot control.
Correct transportation, correct storage and installation and careful use and maintenance are essential for reliable and problem-free operation.
Use the device only as intended.

3 BASIC SAFETY INSTRUCTIONS
These safety instructions do not make allowance for any
•• contingencies and events which may arise during the installation, operation and maintenance of the devices.
•• local safety regulations - the operator is responsible for observing these regulations, also with reference to the installation personnel.
Danger - high pressure.
Before loosening the pipes and valves, turn off the pressure and vent the pipes.
Risk of electric shock.
Before reaching into the device or the equipment, switch off the power supply and secure to prevent reactivation.
Observe applicable accident prevention and safety regulations for electrical equipment.
Risk of burns/risk of fire if used for a prolonged switch-on time through hot device surface.
Keep the device away from highly flammable substances and media and do not touch with bare hands.
Risk of injury due to malfunction of valves with alternating current (AC).
Sticking core causes coil to overheat, resulting in a malfunction.Monitor process to ensure function is in perfect working order.
Risk of short-circuit/escape of media through leaking screw joints.
Ensure seals are seated correctly.
Carefully screw valve and pipelines together.
To prevent injury, ensure that:
Do not make any external modifications to the housing of the device. Ensure that the system cannot be activated unintentionally.
Installation and repair work may be carried out by authorized technicians only and with the appropriate tools.
After an interruption in the power supply or fluidic supply, ensure that the process is restarted in a defined or controlled manner.
Do not put any loads on the body.
The general rules of technology apply to application planning and operation of the device.

Special instructions for valves circuit function B (NO) with deaeration connection G1/8 on the coil (CF05/MX62):
The deenergized valve is open. The medium also flows off via the deaeration connection on the coil.
Valves of this design are therefore suitable for relieving compressors only.
4.2Application conditions
