The illustrations below show how contactors of sizes S00 and S0 are mounted on a
mounting plate:

Step Operating instruction Image
1 Using two M4 screws (maximum tightening
torque 1.2 to 1.6 Nm), plain washers, and
spring washers, screw the contactor tight
into the designated drill holes diagonally.
You can use the 3RT1926-4P screw
mounting adapter to make size S0
contactors easier to mount, if necessary
(e.g. in the case of vertical access when
using an insulated screwdriver). These
adapters can be rotated by 90° as you wish.
