WARNING!
Restricted Access: The Alpha FXM must be installed in a restricted area accessible only
by qualified 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 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 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).
