General terms and conditions
We are not liable for any damage caused by non-observation of this information as well as in case of
improper intervention regarding this device. Furthermore, warranty for the devices and accessories will
become void. Our general terms and conditions apply.
The nass magnet solenoid coil is designed for operation with the nass magnet armature assemblies and
nass magnet valve systems; please consider the corresponding power levels.
Applied standards in the Conformity Assessment:
EN 60079-0:2012+A11:2013
EN 60079-15:2010
EN 60079-31:2014
In its installed state the device is appropriate for potentially explosive gas atmospheres of Group IIC
(protection type “nA”). The Equipment Protection Level (EPL) is Gc for intended application in Zone 2,
ATEX Category 3G. Alternatively the device is appropriate for potentially explosive dust atmospheres
of Group IIIC (protection type “tc”). The according Equipment Protection Level is Dc for intended
application in Zone 22, ATEX Category 3D.
Beyond recognized rules of sound engineering practice these operating instructions refer to special
conditions for safe use as well as to further application conditions that must be observed in any case.
However, these operating instructions cannot consider all possible conditions and applications
completely, and do not replace the specifications valid in each case.

Installation
At installation and maintenance it is essential to observe applicable standards for electrical safety and
electrical installations in potentially explosive atmospheres, especially EN 60079-14.
Installation only in areas with low level of mechanical danger (in accordance with EN 60079-0, Tests
of enclosures), the place of installation must be light-protected.
Install the provided receptacle connector (same number of certificate imprinted) with a suitable
connecting cable together with the solenoid and valve according to these instructions. The Ex suitability
is solely fulfilled when installed completely..
Only single assembly admissible: the minimum distance to the next solenoid shall be at least 70 mm in
order to keep the admissible temperatures (at a duty cycle of 100 %).
After the removal of the packaging, make sure that dirt cannot penetrate into the system and check
that there is no dirt in the piping or the valve housing.
Make sure not to detach pipes and valves of pressurized systems.
Take suitable measures to exclude unintentional activation or inadmissible impairment.
Make sure not to damage O-rings and seals during assembly.
Mounting is admissible in any position. Preferably the solenoid coil points upwards.
The solenoid coil can be locked when offset by 45°.
In case of selection of the valve housing material, the following must be considered:
Plastics: In order to avoid the build-up of electrostatic charges, the requirements according to
EN 60079-0, Section 7.4, must be observed.
When properly installed ingress protection IP65 is achieved. Observe the provided seals and the
prescribed tightening torques pursuant to the assembly scheme. Only use original spare parts provided
by nass magnet, otherwise to this assembly the ATEX attestation of conformity is not applicable any
more.
The cable gland is suited for cable diameters of 4.5 mm to 6 mm or 6 mm to 8 mm, one gasket provided
for each range. Only one gasket at a time shall be used in the gland.
Please observe the respective requirements and ambient conditions (see EN 60079-14) when routing
cables for connection.
Prevent the connecting cables from being buckled and damaged in order to avoid short circuits and
interruptions.
Directly before the connector a strain relief must be provided in order to ensure that strain and torsion
are not transmitted to the connector.
The wire clamps are rated for wire cross sections from 0.5 mm² to 1.5 mm². The tightening torque of
the clamp screw is 0.2 +0.1 Nm.
Single-wired conductors may be used or either multi-wired or fine-wired conductors may be used if
wire end sleeves are applied. The wire ends shall be mounted into the screw joints properly and
undamaged. Only one conductor respectively one end sleeve may be inserted per clamp.
The terminal block can be offset in steps of 90° inside the connector housing such that the cable outlet
direction is adjustable. No further settings are possible.
Before operational start-up of the device, it must be ensured that the entire machine or system
corresponds to the determinations of the applicable EU-directives (e.g. the EMC Directive).

Operation
Caution, danger of arcing! The connector receptacle must not be disconnected from the Ex-solenoid
coil under electrical load!
Caution, danger of ignition! Solenoid coils must not be energized without mounted valve!
Caution! Risk of injury! The solenoid valve can get very hot during continuous operation.
The Ex-solenoid coils Type 0558 of temperature Class T5 are designed for an ambient temperature
range from -20°C to +50°C and media temperatures of -20°C to +50°C.
The operating pressure of the device depends on the armature system employed. The nass magnet
standard armature system is suited for up to 1200 kPa (12 bars) and has no extra identification. For
higher operating pressures further documents are available.
Admissible media are gas and liquids that do not affect the system and the gasket material contained
therein.
Prevent the device’s exterior surfaces from getting in contact with liquid or corrosive media.
Do not strain the system by bending or torsion.
Troubleshooting
At malfunctioning check the cable connections, operating voltage and pressure.
Check that there is no external damage.
Should the problem persist the device must be put out of operation. Make sure to disconnect pressure
and electrical power supply.
Damaged or defective devices may not be repaired but must be replaced.
