Solenoid coil, Type BZ
• Use only for system in compliance with ATEX. Ignition risk is evaluated in accordance to ATEX.
• Coil type BZ can be applied on systems with R290, R600, R600a and R1270 as the working uid.
• For countries where safety standards are not an indispensable part of the safety system Danfoss recommend the
installer to get a third party approval of the system containing ammable refrigerant.
• Please follow specic selection criteria stated in the datasheet for these particular refrigerants.
1.2 Installation, operation and maintenance
• Protect the coil against external impact.
• Protect the coil against direct sunlight and other ultraviolet sources.
• Disconnect the power before dismounting the coil.
• Always install a fuse in front of the coil.
◦ DIN 41571-2
◦ Rated breaking capacity 1500 A
◦ Medium Time lag
◦ Minimum voltage 250 V for AC and 24 V for DC.
• Install the coil and cable according to EN60079-14.
• The cable supplied with the solenoids must not be handled or exed, and shall be protected against impact if the
ambient temperature is below 0 °C .
• Installation and handling of the cable shall be done at temperature above 0 °C.
• The cable is only for xed installation and the minimum bending diameter for xed installation: r ≥ 55 mm
• The cable jacket material is PVC.
• The cable operating temperature range is -40 - 90 °C.
• The product is provided with a yellow / green PE wire as well as an external earth terminal. These shall not be used
simultaneously. If the external earth connection is connected to earth or bonding system, the Y / G earth wire
must be cut o, isolated and not connected. If the Y / G wire is connected to earth, the external earth terminal
must be left without any connection. 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.
• 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.
