 Every single magnet has to be connected with an
external normal-lag fuse according to its rated current
(max. 3 x Inominal).
 We recommend a stabilised power supply. The max. AC-ripple
must not exceed 20%.
 The cable must be installed in a fixed position and protected
against mechanical damage.
 For installation, use and maintenance the official standards
and rules must be applied.
 The temperature class T6 is in accordance with the magnet.
 The force of the magnet can deviate depending on different
types of material, dimension and surface of the anchor.
 A possible remedy would be a thin, non-magnetic foil.

Installation Instructions
1. General Terms
Each piece of equipment may only be used for the respective purpose. By use of the equipment, other than for the
specified purpose, no guarantee can be given.
The magnets are delivered in 3 grades of 650 N, 1300 N and 2000 N.
During the mounting please be aware that the anchor plate and the magnet must be in alignment. The material for
the installation is not included.
Improper installation will lead to breakdowns and a reduction in the force.
It is strictly important to protect this equipment from knocks and vibrations, that are stronger than the nominal force
of the magnets (even for a short time).
Important Note!
It is mandatory that only especially trained personnel should use this equipment. Installation, operation and servicing
of the equipment may also only be carried out by specialist on this field, who are experienced with the dangers
and have also read and understood the instructions.
Proper transportation, storage, installation (within the specialised area) and maintenance, are absolutely necessary
for precise and exact usage.
Should the equipment show damage that leaves the assumption that safe use is not possible the equipment must
not remain in operation and must be decommissioned.
If the explosion proof equipment is operated in aggressive surroundings (e.g. in the chemical industry or off shore,
on shore) it should be cleared that the casing or parts of such are suitable for the surrounding conditions. In case
of ambiguities or for information that hasnt been provided please contact your dealer or our centre.
Customers may not open the magnet (loss of explosion protection and lapse of guarantee claims).
The assembly may be carried out only by skilled electrical personnel in accordance to EN 60079-14 / DE 0165
and such skilled personnel, who comply with the guidelines prevalent in the respective country.
The regulations on electrical apparatus in explosion proof areas (Ex O) must be adhered to ! In addition to this,
the rules and regulations which may possibly vary in other countries outside the EU.
The magnet itself is maintenance free. The servicing is only related to the inspection of the casing for damage and
the functioning of the equipment which should be inspected e.g. 1-2 times a year (Ex-protection guarantee)
The ATEX 118a as well as the Ex O are applicable within the EU in general, whereas national guidelines and
regulations are to be observed in other places. For non EU zones, the corresponding national guidelines and
regulations are applicable.
2. Type Designation
The type designation structure for different types can be found in the diagram. (example)
3. Electrical Connection
Electrical installation must be performed according to the rules and regulations of the respective country. The
connection must be executed as in the following wiring diagram.
During the electrical installation and the start up of explosion proof equipment the rules and regulations for installation
of electrical equipment in explosive hazardous areas of the respective countries must be followed. Differences
are also nationally possible.
Electrical connections inside the Ex-area are only allowed to be installed by means of Ex e connection clamps.
During this procedure you must take into account that the cable glands must be tighten completely by the contractor.
The terminal box must not be opened when the voltage is on!
Electric wires must be secured and must be so laid out that they are sufficiently protected against damages.
The electrical connections of the magnet must always be made with the current switched off.
The operating voltage of the magnet is indicated on the name plate. Please compare with supply voltage.
The Schischek Company does not accept damaged magnets because of excess voltage as case of guarantee
demands.

4.Commissioning
Before the equipment is switched on it must be tested that the voltage is 24 DC +/- 10%.
The magnet should show no sign of mechanical damage (ex-protection).
The commissioning starts with the inspection of the installation of the magnet and the anchor-plate , the
wiring and the following function-control.
Furthermore, all the ex-relevant components, that are found between the magnet and the switch-gear in the
hazardous area, should be examined to ensure no damage has been done and that the installation is correct.
5. Decommissioning
Before switching off, consider the effects on the system as well as on the following devices. Disconnect the
main connection before starting mechanical dismantling. The terminal box must be free of voltage.
6. Maintenance
The magnet should never be opened by the operator (loss of the Ex-protection). Please exchange damaged
terminal boxes or magnets for new ones immediately, or have them overhauled at Schischek GmbH.
7. Checklists in the event of Operational Difficulties
Problem Possible cause Solution
Magnet does not provide - Mains failure Check mains, establish mains again
enough force. - Incorrect mains voltage Magnet must be repaired by manufacturer.
- Magnet connected incorrectly If the magnet has now been connected correctly
and still does not function, the magnet has to
be repaired by manufacturer.
- Magnet and anchor plate Check mounting of both parts
are not in alignment
- Wrong choice of magnet Choose stronger magnet
(force insufficient)
Magnet function is occasionally - Loose contact in the feed lines Check and secure connections.
interrupted - Loose contact inside the magnet Magnet must be repaired by manufacturer
- Increase of temperature Check ambient-temperature
