Installation Guide

This guide provides instructions for the installation of the Danfoss Solenoid Coil Type BI, designed for use in potentially explosive areas.

Identification:

• Green/Yellow cord for earthing
• Week and date of manufacturing
• External earth terminal
• Code number
• Voltage
• Approval/Certificate number
• Frequency
• Ambient temperature range
• Country of manufacturing
• Approval logos

EX Certifications:

• Ex mb IIC T4 Gb
• IECEx ULD 21.0024X
• UL 21 ATEX 2606X
• UL21UKEX2374X

Coil Installation Steps:

1. Ensure the solenoid coil is protected against impact during use.
2. Protect the coil against direct sunlight and other ultraviolet sources.
3. Disconnect the power before dismounting the coil.
4. Install the coil and cable according to IEC/EN/ EN BS 60079-14.
5. The cable supplied with the solenoids must not be handled or flexed, and shall be protected against impact if the ambient temperature is below 0 °C.
6. Install the coils in the orientation shown in the diagrams.
7. The permitted process medium temperature range is -40 °C to +90 °C.
8. The capacitance of exposed, isolated, metallic parts is 7pF.
9. The cable is only for fixed installation and the minimum bending diameter for fixed installation: r ≥ 35 mm [arrow].
10. The cable jacket material is PVC.
11. The cable operating temperature range is -40 – 90 °C.
12. The product is provided with a yellow/green PE Conductor as well as an external earth terminal. These shall not be used simultaneously.
13. If the external earth connection is connected to earth or bonding system, the PE Conductor must be cut off, isolated and not connected.
14. If the PE Conductor is connected to earth, the external earth terminal must be left without any connection.
15. For the external earth terminal, the size of the earth core shall be minimum 4 mm² and the installer shall use a suitable method e.g. crimp terminal to ensure secureness of the external earth connection. The screw for external PE shall be mounted with 1.2 Nm ± 0.2. The external earth conductors shall be physically secured close to the coil connection to ensure that the conductors cannot be readily loosened or twisted.
16. The end user must ensure the earthing of the coil is maintained.
17. Non-detachable cords method Z repairing not allowed. If the coil failed, it must be replaced by a new coil.
