Information
The encoder supply on X48A to X48D is short-circuit proof on both 5 V and
11 V operation. The module remains in operation enabling the generation
of a corresponding error message when evaluating the encoder signals.

Operation on special systems
TN- and TT system
The operation is only permitted if for three-phase devices with external con-
ductor voltages 3x 230 V AC, 3x 400 V AC, 3x 480 V AC the star point of the
supply system is earthed and the supply system conforms to the maximum
overvoltage category III as per EN 61800-5-1 at a system voltage (external
conductor → star point) of maximum 277 V.
IT system
The operation is only possible for three-phase supply with 3 x 230 V. The
compliance of EMC directives 2014/30/EC has to be ensured by the user!
The operation for three-phase supply with 3 x 400 V or 3 x 480 V is not per-
mitted! Otherwise, in case of an earth fault the electrical stress is approx.
twice as high. Clearances and creepages to EN 61800-5-1 are no longer
maintained.

DIP-Switch (S-ADR)
The DIP-Swith S-ADR is located on the bottom side of the module and
serves for configuration of the safety functions of the D3-DA 3xx/x. For more
