WARNING!
Restricted Access: The Alpha FXM must be installed in a restricted area accessible only
by qualied service personnel.
The Alpha FXM is intended for permanent AC connection only. The only exception is the
FXM650(U) model.
The Alpha FXM must be correctly grounded for proper operation. Older facilities may
have inadequate electrical grounding. Inspection must be performed by a qualied elec-
trician 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
certied for this use in accordance with the local electrical code. The UPS must be con-
nected only to a dedicated branch circuit.
The UPS equipment that is powered by this service panel requires the neutral to be per-
manently 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 Na-
tional Electrical Code applies.
Grounding: The Alpha FXM is suitable both for installation as part of a common bonding network and an iso-
lated 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 for
every 300 m (1000 ft) above 1400 m (4500 ft).
3.1 Safety Precautions
• Install the Alpha FXM on a surface that can support its weight. See "Specifications".
• The input wiring must reach a suitably grounded power outlet and the load wiring must reach the
Alpha FXM’s output terminal blocks.
• The Alpha FXM should be placed at a properly sheltered location or inside a weather-proof enclosure to
protect the electronics from water, dust and other possible contamination.
• Alpha Technologies offers a wide range of outdoor enclosure systems. Visit our website at www.alpha.ca,
