接触器可借助接触器底上滑鞍扣装在35mm宽的标准安装导
轨（DIN EN 50 022）上。或用2只M4螺钉安装，用螺钉安装
时，一定要装平垫圈和弹簧垫圈。在安装时要防止外来颗
粒，例如防止细铁屑进入里面。如果接触器暴露于灰砂、粉
尘及腐蚀性环境中，应加装防护罩。

Operation
Observe operating voltage ( see rating plate of magnet coil ).
The operating state of the contactor is shown by the position of the contact carrier; see
Fig. IV.
! When the system voltage is applied and the load is connected, do not operate the
contactor by pressing down the contact carrier.
Maintenance
The following components can be replaced:
magnet coil, single-pole auxiliary contact block 3TX40
For Order No. see Catalog.
Only use of original spare parts ensures the operational safety of the contactors.
Cleaning
Remove dust by suction
.
Auxiliary contact block
For replacement see Fig. V.
Magnet coil
For coil replacement see Fig. VI: - Fig. VI a a.c. coil
Ensure that the pole faces of the magnet coil are clean. Do not use grease solvents or
sharp objects for cleaning.
