When installing the module in the housing FDCH221, proceed as follows:
1. Break out the cable entries.
2. Mount the housing on a flat surface.
The housing cover is transparent so the LEDs can be seen at all times. Pick a
suitable mounting position, ensuring that the LEDs will remain visible at all
times during operation.
3. Insert cables. If necessary, secure cables with the M20 cable glands or use a
different cable entry.
4. If necessary, press the auxiliary grounding terminals into the back box. Then
connect the shielding. The shielding must not touch any extrinsic potentials to
ground or metal parts in the device.
5. Install the module in the housing.
6. Connect the cables to the corresponding terminals. Only connect one wire per
terminal.
7. Close the housing by snapping the housing cover into place.
The screws supplied must always be used for the housing with seal.
If the cable diameters on the inputs/outputs are greater than 1.5 mm
terminals must be used:
In the case of cables with a diameter of 1.5...2.5 mm
DBZ1190-AB can be used.
For larger diameters, the customer should procure a suitable terminal.
The terminal can be positioned inside the housing.
