4 Safety

4.1 General safety instructions

• The device can be used under the stated operating conditions in zones 1 and 2, explosive gas atmospheres, and in zones 21 and 22, explosive dust atmospheres.
• The device may only be used in the delivered configuration in a potentially explosive atmosphere.
• Use the device in its original status without any unauthorised modifications.
• All work must be carried out outside of potentially explosive areas.

4.2 Intended use

The solenoid coil is an actuator for Festo valves.

4.3 Identification X: special conditions

• Install a fuse or a motor protection switch appropriate for the rated current upstream of the solenoid coil as short-circuit protection.
• Short circuit protection for max. 3 times the rated current in accordance with IEC 60127-1.
• The fuse with the lowest current value in accordance with IEC 60127-1 is sufficient for very low rated currents of the solenoid coil.
• Select the fuse rated voltage equal to or greater than the nominal voltage of the solenoid coil.
• Motor protection switch with short circuit triggering and thermal quick triggering, adjustment to rated current.
• Install the fuse in the supply unit or wire it separately upstream.
• The interruption rating of the fuse unit must be greater than or equal to the maximum expected short-circuit current at the installation location, normally 1500 A.
• Max. permissible ripple with solenoid coils in direct current: 20%.

5 Function

When switching on the voltage, the solenoid is energised, and the valve is actuated.

6 Commissioning

WARNING

The discharge of electrostatically charged parts can lead to ignitable sparks.

• Prevent electrostatic charging by taking appropriate installation and cleaning measures.
• Include the device in the system equipotential bonding.

NOTICE

Installation and commissioning should only be carried out in accordance with operating instructions and by qualified personnel.

• Prevent short circuit or interruption resulting from bending the connecting cable too tightly.
• Observe the product labelling.
• Do not commission the solenoid coil until after mounting.

7 Maintenance and care

WARNING

The discharge of electrostatically charged parts can lead to ignitable sparks. If used in group IIC:

- Only clean the device with a damp cloth.

– Repairs to the solenoid coil are not permitted.
- The device is maintenance-free.
