The installer must fix the cable in a
position close to the coil to ensure
that the first 20 mm cannot be bent.

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 involves 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.
Safety requirements for use in explosive
atmospheres are fullfilled through
compliance certificates:
• EX mb IIC T4 Gb
• DEMKO 14 ATEX 1314X
• IECx ULD 14.0001X
• UL21UKEX2020X
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
• An external fuse (standard DIN41571-2) is
required to protect coils as follows:
018F4703: 250 mA, 1500 A Breaking capacity,
250 V, Medium Time lag
018F4704: 150 mA, 1500 A Breaking capacity,
250 V, Medium Time lag
018F4705: 500 mA, 1500 A Breaking capacity,
250 V, Medium Time lag
The Power supplying the solenoid must be
limited to a prospective short circuit current
of a maximum 1500 A
• Install the coil and cable according to
IEC/EN/ EN BS 60079-14
• 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
• Installation and handling of the cable shall
be done at temperature above 0 °C
• The cable is only for fixed installation and
the minimum bending diameter for fixed
installation: r ≥ 55 mm ( 2 )
B
• 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 off, isolated and not con nected. 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
