In drives that have an 0 or 1 suffix (only for 400V models), a smart control-supply algorithm enables
the Gold Panther to operate with the main power supply only, with no need for an auxiliary supply
voltage to supply the drive’s logic section. However, it should be noted that in such model there is
no backup ability at all.
If backup functionality is required to store control parameters in the event of a mains power
outage, then an S or T-model Gold Panther should be used, with an external 24 VDC isolated supply
connected to it.
Note that the S or T-model Gold Panther always requires an external 24 VDC power supply,
regardless of whether or not backup functionality is required.
Connect the auxiliary 24 VDC power supply as described below.
To connect the 24 VDC backup supply:
1.
Use a 24 AWG twisted pair shielded cable. The shield should have copper braid.
2.
The source of the 24 VDC backup supply must be isolated with an isolation transformer.
3.
For safety and EMI reasons, connect the return of the 24 VDC backup supply to the closest
ground (PE).
4.
Connect the cable shield to the closest ground (PE) near the power source.
5.
Before applying power, first verify that the polarity of the connection is correct.
