However, as well as operating from a non-isolated/direct-to-mains DC power supply, the Gold
Drum HV (High Voltage) can also operate from an isolated power supply or batteries.
When rectifying an AC voltage source, the AC voltage level must be limited to 270 VAC so as
not to exceed the maximum 390 VDC in the case of a 400 VDC drive, or 528 VAC so as not to
exceed the maximum 747 VDC in the case of an 800 VDC drive.

Direct-to-Mains Power Source (Non-Isolated Rectifier)
This section relates to the configuration of the power supply and drive, which are connected
directly to the mains.
To connect the non-isolated DC power supply:
1.
For best immunity, it is highly recommended to use twisted cables for the DC power supply
cable. A 3-wire shielded cable should be used. The gauge is determined by the actual
current consumption of the motor.
2.
Connect both ends of the cable shield to the closest PE connections.
3.
Tie one end to the power supply’s PE terminal, and tie the other end either to one of the
four mounting screws of the drive’s heat sink-PE.
4.
To close the power supply cable into the drive, use the barrel connector, M6 spring washer
and M6 nut (in the drive). The required torque is 3 to 4 Nm.
5.
To close the PE wire into the drive, use the barrel connector, M6 flat washer, M6 spring
washer and M6 screw to the heat sink. The required torque is 3 to 4 Nm.
