Procedure:
1. Disconnect the product from voltage sources (see Section9, page45).
2. Connect the connection cable to the digital signal source (see the manual from manufacturer).
3. Dismantle the connection cable 150mm.
4. Strip off the insulation of required conductors by 6mm.
5. Trim unused insulated conductors flush with the cable sheath.
6. If necessary, fit the conductors with bootlace ferrules.
7. Pass the connecting cable through the cable gland for connecting a signal source to the digital
