lay & Load Shed" on page 53 for web and Alpha UPS Monitor, and "7.5.4 Programming the Dry Contacts" on
page 82 for HyperTerminal.
C1: The C1 contact is energized when line power is unqualified and the Alpha FXM provides backup battery
power to the load(s). Can be used to generate an “On Battery” alarm.
C2: This contact is energized when the battery drops below a pre-set voltage level. Can be used to generate
a “Low Battery” alarm. You can change the pre-programmed level to match the batteries used and the actual
operating conditions. See "Adjusting and Controlling the Alpha FXM" on page 81: #35 Low Battery Warning
Voltage.
Replaceable fan assembly
This microprocessor-controlled fan regulates the Alpha FXM internal temperature for optimum performance.
Microprocessor-control of the fan speed increases the life of the internal electronics and the fan.
Take care that the fan is not blocked. Failure of the fan generates an alarm; the internal fan assembly is
designed so it can be replaced if it fails.

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.
Page 15 to 106

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
specified by local, national, and/or other applicable government codes and regulations.
The customer facilities must provide suitable surge protection.
To meet FCC Class B requirements, follow the instructions in section 5.1.4 to attach a ferrite ring to the
connector end of your RJ45 network cable.

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.
