Geo Direct PWM Amplifier
Connector PinOuts and Wiring 22
Recommended Bus Power Fuse and Wire Gauge
Geo Drive electronics create a DC bus by rectifying the incoming AC lines. The current flow into the
drive is not sinusoidal but rather a series of narrow, high-peak pulses. Keep the incoming impedance
small so that these current pulses are not hindered. Conductor size, transformer size, and fuse size
recommendations may seem larger than normally expected.

Note
All ground conductors should be 8AWG minimum using wires
constructed of many strands of small gauge wire. This ensures the
lowest impedance to high-frequency noises.
