an isolated bonding network.
For installations above 1400 m (4500 ft) elevation, additional cooling may be needed to reduce the operating temperature of the Alpha FXM. The maximum allowable operating temperature must be reduced by 2°C
(3.5 °F) for every 300 m (1000 ft) above 1400 m (4500 ft).
3.1 Safety Precautions
• Install the Alpha FXM350 and Micro350 and batteries on a surface that can support the total weight. See
Chapter "10. Specifications" on page 98.
• The input wiring must reach a suitably grounded power outlet and the load wiring must reach the
Alpha FXM350 and Micro350 output terminal blocks.
• Place the Alpha FXM350 in a properly sheltered location or inside a weather-proof enclosure to protect
the electronics from water, dust and other possible contamination.
• Backup Generator (If used)
In Generator mode, the Alpha FXM range of acceptable input frequency and voltage is expanded to
accept the fluctuations created by a generator. See "7.2.2 The LCD Control Menu" on page 45, Table B,
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 Battery
mode. Before installation, make sure the generator’s output voltage is compatible with the Alpha FXM
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.

3.3.1 Battery Heater Mats
The FXM350 and Micro350 allow connection, on its front panel, of a battery heater mat without a thermostat
(#14 in Figure 3). Maximum power of the battery heater mat for use with the FXM350 connector is 55W. The
FXM turns the heater mat on when the temperature measured by the battery temperature sensor senses a
temperature < 5°C. It turns the heater mat off when the temperature raises to >15°C. For the Micro350XL or
bigger systems needing more than one heater mat, it is recommended to use the heater mats with built in
thermostat and daughter heater mats that can be daisy chained. These heater mats may be wired to the AC
in the terminal block on the distribution panel. Ensure that the input breaker is appropriately rated.
