WARNING:
HAZARDOUS VOLTAGE
CAN CAUSE ELECTRICAL SHOCK
AND BURNS.
DISCONNECT POWER BEFORE PROCEEDING
WITH ANY WORK ON THIS EQUIPMENT.
Installation
For dimension drawings (dimensions in mm) see
> Fig. I a
> Fig. I b
a.c. operated
d.c. operated
1) Minimum clearances from earthed parts
Snap onto 35 mm standard mounting rail to DIN EN 50 022 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. II a a.c. operated
> Fig. II b d.c. operated
Connection
The terminal screws can be tightened with a power screwdriver.
Screwdriver blade width: 5 to 6 mm
Permissible cross>sections for main and auxiliary conductors :

2¥0.5 to 1 mm2
2¥1 to 2.5 mm2
1¥4 mm2
2¥0.75 to 2.5 mm2
AWG wires

Tightening torque standard type
0.8to 1.4 Nm/7 to 12 lb.in
Tightening torque auxiliary contact block 0.8to 1.1 Nm/7 to 10 lb.in
Use 75 ∞C copper wire only.
For circuit diagram and position of connection terminals see Fig. III.
For circuit diagram (NEMA) see Fig. A.

> Fig. III c without auxiliary contacts
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 and single>
pole auxiliary contact block 3TX40.
For Order Nos. see Catalog NSK.
Only use of original spare parts ensures the operational safety of the
contactors.
Magnet coil
For coil replacement see Fig. VI.
> Fig. VI a a.c. coil
> Fig. VI b d.c. coil
Ensure that the pole faces of the magnet coil are clean. Do not use grease
solvents or sharp objects for cleaning.
