Connecting the DC Output Cable
To connect the DC output cable:
1.
For best noise immunity, a shielded and twisted cable is recommended (not mandatory) for the
DC output cable. A 3-wire shielded cable should be used. The gauge is determined by the actual
current consumption of the drives being fed by the relevant DC output.
2.
Connect the three wires of the DC output cable to the DC output connector of the
Tambourine 20:
a. Connect the DC leads to the VP+ and VN- terminals of the DC output connector.
b. For safety requirements, the third green/yellow-wire must be connected to the protective
earth (PE terminal). Connect the Protective Earth wire to the PE terminal on the DC output
connector.
3.
When the Tambourine 20 is fed from an isolation transformer, from the safety and EMI aspects,
the PR (VN-) junction must be connected to PE junction.
