Fasten the mounting plate onto the spacer bolts with the
countersink screws.

NB: The countersink must be on the upper surface, so that
the countersink screws are flush with the surface after fitting..
3 
Fasten the base housing of the SK SSX-3A to the mounting
plate with two cylindrical-head screws and lead the
connecting cable from the SK SSX-3A to the connection unit

3.1.2 Connection
The Simple Setpoint Box provides various operating modes. The connection of the data or supply cables must be
made in different ways, depending on the required operating mode. Connection is made to the terminal bar by
means of a 3 or 4 wire cable. For a description of the terminal connections, please refer to Section 3.1.3 .
Connection data:
Name Value
Rigid cable cross-section 0.14 … 2.5mm²
Flexible cable cross-section 0.14 … 1.5mm²
AWG standard AWG 26-14
Tightening torque for screw
terminals 0.5…0.6Nm
The connection cable must be fed out of the device via a cable gland (supplied). The cable gland must be screwed
into the rear section of the housing.
It is recommended that the length of the connection cable is limited to 20 m. The cable should be laid separately
from other cables to avoid interference.
