3. Site Planning
WARNING!
Restricted Access: The Alpha FXM350 and Micro350 must be installed in a restricted area accessible only by qualified service personnel.
The Alpha FXM350 and Micro350 are intended for permanent AC connection only.
The Alpha FXM350 and Micro350 must be correctly grounded for proper operation. Older facilities may have inadequate electrical grounding. Inspection must be performed by a qualified electrician before installation to ensure that grounding meets the local electrical code.
The utility line attached to the Alpha FXM input MUST be protected by a circuit breaker certified for this use in accordance with the local electrical code. The UPS must be connected only to a dedicated branch circuit.
The UPS equipment that is powered by this service panel requires the neutral to be permanently bonded to the ground. Always disconnect the batteries before servicing the circuit breaker panel.
The input and output lines to and from the Alpha FXM MUST have disconnect devices attached.
The Alpha FXM is suitable for installations in network telecommunication facilities and locations where the National Electrical Code applies.
Grounding: The Alpha FXM is suitable both for installation as part of a common bonding network (CBN) and 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.
