Safety instruction

All national safety regulations must be complied with in connection with installation, start-up and operation of Danfoss solenoid valve. Furthermore the requirements of the declaration of conformity and national regulations for installation in explosion area. Disregarding such regulations in-volves a risk of serious personal injury or extensive material damage. Work in connection with the solenoid valve mentioned must be performed only by suitable qualified persons. Basic safety and health requirements are fulfilled through complains with:

• EN60079-0: 2012 + A11: 2013
• EN60079-0: 2018
• EN60079-18: 2015 + A1: 2017

Installation, operation and maintenance

• The coil must be protected against external impact.

• If the coil is installed in wet environment (pollution degree 3) the coil shall be mounted with wet kit accession 018Z0090.

• Always install a fuse in front of the coil.

  • DIN 41571-2
  • High breaking capacity 1500 A
  • Medium Time lag
  • Minimum voltage 250 V

• Ensure that the o-ring is proper mounted. This is done by position the O-ring in the middle of the armature tube, and let the coil push the O-ring into position at the bottom of the armature tube ( C ).

• The cable supplied with the solenoids must not be handled or flexed and protected against impact if the ambient temperature
  is below 0 °C or similar. Minimum bending diameter for fixed installation: 35 mm ( B ).

• Mount the aluminum cap with 1.5 Nm+/-0.15 ( C ) and ensure that the O-ring is placed correct.

• The end user must ensure the earthing of the coil is maintained.

• Non-detachable cords method Z repairing not allowed. If the coil failed, it must be replaced by a new coil.

Special Conditions of Certification/Use

• For Solenoid in use under -30 °C the cable must be protected from impact
•  The Solenoid is manufactured with a permanently connected cable. The connection of this cable sup-plying the solenoid must be done in accordance with the appropriate electrical code and good engineering practice
• The product is provided with a Y/G coloured earth wire for internal earthing. This internal earth connection shall not be used if the external earth connection is connected to the earth or bounding system and must be cut off, isolated and not connected.
• The solenoid must not be removed from the valve when energized. This would otherwise impair the surface temperature specifications.
• Enclosures or parts of enclosure are non-conduct-ing and may generate an ignition capable level of discharge under certain extreme conditions. The user shall ensure that the equipment is not installed or used in a location where it may be subjected to external conditions (such as high-pressure steam) which might cause a build-up of electrostatic charge or non-conducting surfaces. Additionally, cleaning of the equipment shall only be done with a damp cloth.
• The solenoid must be protected against direct sunlight and ultraviolet sources.
• The power supplying the solenoid must be limited to a prospective short circuit current of 1500 A according to EN 60079-18:2015 clause 7.9.2.1
• Each product shall be subjected to a visual inspec-tion according to EN 60079-18:2015 clause 9.1
• Each product shall be subjected to a Dielectric strength test according to EN 60079-18:2015 clause 9.2

Warning

Potential Electrostatic Charging Hazard. The solenoid valve must only be installed in surroundings with low wind speed, and where rub-bing the coil is unlikely. Cleaning with damp cloth is recommended. To avoid buildup of electrostatic discharge it must be ensured the coil is having a reliable connection to earth with an impedance no exceeding 1
