connected to protective earth.
3. Motor and signal cables must be shielded. The cable shielding must be
connected conductively to the housing.
4. The transformer must be constructed with reinforced or double insulation to
avoid dangerous touch voltages (50 V
AC
and 120 V
DC
) in case of error.
The secondary winding of the transformer shouldn’t be grounded (SELV
supply) (acc. to DIN VDE 0550 or DIN EN 60742).
