Contactor
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 see Fig. I (dimensions in mm)
Fix on a plain surface with two M4 screws - max. tightening torque 3.1 Nm. 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 atomspheres.
For permissible mounting positions see Fig. II.
Connection
Tighten all terminal screws even if not used.
Permissible conductor cross-sections for main terminals:
With box terminal

The ends of non-stranded cables must be twisted or 18 mm long end sleeves to
DIN 46228 Part 1 must be used.
Crimping tools PZ18 and PZ35 from Weidmuller are recommanded for the end
sleeves.
Before mounting the box terminals (see Fig. IIIb), the arc chute must be removed
(see Fig. VII / 1, 2, 3).

Use 75 °C copper wire only.
**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.

Operation
Observe operating voltage (see rating plate of magnet coil).
The operating state of the contactor is shown at the position indicator; see Fig. V.
After a short circuit the main contacts and the arc chute must be checked.
Maintenance
The following components can be replaced: Main contacts, arc chute, magnet coil,
auxiliary contact blocks. - For Order Nos. see Catalog.
Cleaning
Remove dust by suction.
Auxiliary contact block
For replacement see Fig. VIa / 1, 2, 3; for extension see Fig. VIb / 4, 5, 6.
Arc chute and main contacts
Remove arc chute (Fig. VII / 1, 2, 3). Check main contacts (Fig. VII / 4). If neces-
sary, separate slightly welded contacts with a screwdriver.
Dark or rough contacts can still function. Do not refinish or grease them. If the con-
tact facings are so badly eroded that the carrier material is visible (Fig. VII / 4a), all
contacts must be replaced.
For replacement of contacts see Fig. VII / 5, 6, 7.
It is not necessary to disconnect the main conductors. Check the arc chute and
replace it if necessary.
With the arc chute removed, the contactor is mechanically interlocked. Coil excita-
tion is not permitted under these conditions.
Magnet coil
For coil replacement see Fig. VIII
Ensure that the pole faces of the magnet coil are clean. Do not use grease solvents
or sharp objects for cleaning.
