In the Generator mode, the Alpha FXM’s range of acceptable input frequency and voltage is expanded to
accept the fluctuations created by a generator. See “Operating the Alpha FXM, Sense Type”.
Use a generator with electronic speed and voltage controls which produces less than 10% voltage total
harmonic distortion (THD). Mechanical governors can force the Alpha FXM to run continuously in the Battery
mode. Before installation, make sure the generator’s output voltage is compatible with the Alpha FXM’s input
voltage requirements. To make sure the system runs smoothly, use a generator that supplies twice as much
power as drawn by the total load.
3.2  Electromagnetic Compatibility (EMC) Requirements
Observe the following EMC requirements when setting up the Alpha FXM and its internal equipment:
All AC mains and external supply conductors must be enclosed in a metal conduit or raceway when speci-
fied by local, national, and/or other applicable government codes and regulations.
The customer facilities must provide suitable surge protection.
