4.7.2.2. Battery Power Supply
Figure 12: Battery Connection Topology
Caution: When using batteries, it is recommended to connect the negative pole
to the PE.
When doing so, the charger of the battery
must be isolated from the mains by
an isolation transformer.
4.7.3. +24 V Auxiliary Supply (J3)
Pin (J3) Function Pin Positions
1 +24 V Auxiliary Supply Input Positive
2 24 V RET Auxiliary Supply Input Return
Table 10: Auxiliary 24 VDC Backup Supply Pins and Polarity
In drives that have an 0 or 1 suffix (only for 400V models), a smart control-supply algorithm
enables the Gold Trombone 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.
