Operating Instructions
Read and understand these instructions before installing,
operating, or maintaining the equipment.
DANGER
!
Hazardous voltage.
Will cause death or serious injury.
Turn off and lock out all power supplying this device before
working on this device.
CAUTION
Reliable functioning of the equipment is only ensured with
certified components.
Mounting
For dimension drawings (dimensions in mm) see:
Fig. Ia
Fig. Ib
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:
Fig. IIa
Fig. IIb
Connection
The terminal screws can be tightened with a power screwdriver.
Screwdriver blade width: 5 to 6 mm.
Permissible Conductor Cross-sections for main conductor:
Solid
Finely stranded with end sleeve
Terminal pin in accordance with DIN 46231
AWG wires
Tightening Torque
Permissible Conductor Cross-sections for auxiliary conductor:
Solid
Finely stranded with end sleeve
Terminal pin in accordance with DIN 46231
AWG wires
Tightening Torque standard type
Tightening Torque auxiliary contact block
Use 75 °C copper wire only.
For circuit diagrams and positions of connection terminals see Fig. III.
Operation
Observe operating voltage (see rating plate of magnet coil).
The operating state of the contactor is shown at the position indicator; 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 3TX3.
For Order No. see Catalog NSK.
Only use of original spare parts ensures the operational safety of contactors.
Cleaning
Remove dust by suction.
**Footnote: According to IEC 60947 / VDE 0660, the types of protection mean:
"Assignment type 1": Short circuits can cause damage to the contactors making replacement of the equipment necessary.
"Assignment type 2": Easily separable contact welding but no other damage.
