Cautions and warnings



It is not allowed to use the contactor outside of the parameter range specified in this data sheet.

This also includes temperature and humidity. Overloading may destroy the component.



It must be ensured that during usage, storage or transportation, direct sunlight is avoided. The

ambient temperature during usage must not exceed the value specified in this data sheet.



This contactor is not waterproof.



The manufacturer cannot be held liable for failures caused by condensation or icing. The

customer must apply suitable measures to avoid these circumstances.



It is forbidden to use this contactor in atmospheres loaded with organic solvents (alcohol,

petroleum, etc.) or strong alkaline substances (ammoniac, acids in general, etc.).



We strongly recommend implementing redundancy, taking measures to prevent the spread of

fire, taking the possibilities of malfunction into account and performing regular maintenance.



Contactors must be handled with care and must not be dropped.



Contactors radiate magnetic and electromagnetic fields. Please ensure that other components

mounted in proximity are not affected.



This contactor is tested and classified according to UL as an open-type device. This means that

the contactor is intended to be installed in an ultimate enclosure provided by a third party.

Furthermore, the contactor coil circuit is intended to be powered with a Class 2 source.



The contactor must be mounted onto a flat surface using the designated fixation holes in addition

to the cable lugs or busbars attached to the main connection terminals. It is not allowed to mount

the contactor using only busbars.



The contactor must be mounted in a way that the vertical axis of the part (Z-axis) is not in line

with the main shock axis of the application. Still, it must be mounted either upright standing or

horizontal lying on either side. Upside down mounting must be avoided. Only the original

mounting holes are allowed to be used to mount the part.



In case two contactors are mounted in proximity, a clearance distance of 10 mm must be kept.



It is forbidden to attach any kind of additional construction to or on the contactor.



During installation and operation of the contactor, it must be ensured that no foreign matter

adheres to the main connection terminals. Especially oils and silicones must be avoided.



The cable lugs or busbars to the main contacts must be securely tightened. Otherwise, current

stress may generate sparks and heating. Use only suitable tightening material (screws, bolts or

nuts) for all mechanical connections to the contactor and verify their functionality in the

application. The torque range recommended in the data sheet is suitable for multiple fixation; the

maximum torque is suited for one time fixation only.



Attached wires and plugs are not allowed to be used for lifting and handling the part (maximum

allowed pull-force is 10 N).



For parts with outer copper threads, a slight elongation of the thread is possible when doing

multiple fixations. This may prevent proper fixation when changing the mechanical setup.



It is required to always use a suitable backup fuse for the contactor.



Contactors may become hot during extended periods of current overload (burn hazard).



The main connections of the contactor act as a heat sink. Please ensure that the connection

surface area is fully covered with a matched cable lug or busbar and that the connection hole in

the cable lug or busbar is according to DIN ISO 20273 (middle clearance).
