Operating Instructions
English
For dimension drawings (dimensions in mm) see:
Snap onto 35 mm standard mounting rail to DIN EN 50022 or fix on a plain surface
with two M4 screws. With screw mounting, always use plain washers and spring
washers. Cover the contactors during installation if foreign particles, such as swarf,
can fall onto them. Install contactors in a housing if they are exposed to dirt, dust or
aggressive atmospheres.
For permissible mounting positions see:
The terminal screws can be tightened with a power screwdriver.
Screwdriver blade width: 5 to 6 mm.
Permissible Conductor Cross-sections for main conductor:
Permissible Conductor Cross-sections for auxiliary conductor:
Use 75 °C copper wire only.
For circuit diagrams and positions of connection terminals see Fig. III.
Observe operating voltage (see rating plate of magnet coil).
The operating state of the contactor is shown at the position indicator; see Fig. IV.
.
Maintenance
The following components can be replaced:
magnet coil, single-pole auxiliary contact block 3TX3.
For Order No. see Catalog NSK.
Only use of original spare parts ensures the operational safety of contactors.
Cleaning
Remove dust by suction.
Auxiliary contact block
For replacement see Fig. V.
In addition to the side-mounted auxiliary contact block, a maximum of 2 front-mounted
contact block can be snapped on to the contactor.
Operating range of the magnetcoils (with side-mounted aux. contact block):
3TX4011-8A or 3TX4011-8A + 1 front-mounted auxiliary contact block: AC / DC 0.8
to 1.1 X Us
3TX4011-8A + 1 front-mounted auxiliary contact block: ≤ (0.85~1.1)Us
Magnet coil
For coil replacement see Fig. VI:
Ensure that the pole faces of the magnet coil are clean. Do not use grease solvents
or sharp objects for cleaning.
