2. General Description 2.1 Overview The Alpha FXM is available in 3 models – FXM 650, FXM 1100 and FXM 2000. The FXM 650 and the FXM 1100/2000 look different, but all of the front panel connectors and circuit breakers operate in the same way. However the circuit breakers for each unit have different ratings. See Chapter "9. Specifications" for details. All units operate in the same way unless stated otherwise in this manual. • FXM 650-24Vdc – with a 24 Vdc battery string voltage.
1 Battery breaker This circuit breaker provides over-current protection and is used as an on/off switch for the battery power. It must be switched on for proper Alpha FXM operation. 2 Battery connector The battery connector connects the external batteries to the Alpha FXM. 3 Replaceable fan assembly This microprocessor-controlled fan turns on at a programmable temperature to lower the Alpha FXM internal temperature. It must not be blocked.
C1: The C1 contact is energized when line power is unqualified and the Alpha FXM provides backup battery power to the load(s). It can be used to generate an “On Battery” contact. C2, C3: These contacts are energized when the battery drops below a pre-set voltage level. They can be used to generate a Low Battery alarm. To change the pre-programmed level to match the batteries used and the actual operating conditions, see Low Battery Warning in "UPS Maintenance > Battery" on page 38.
ATS (C8): When the Alpha FXM is in the Inverter mode, this normally open relay closes sending 48 Vdc (FXM 650-48, 1100, 2000) or 24 Vdc (FXM 650-24) from the external batteries to this dry contact (Figure 5). If the optional Alpha Off-Line Automatic Transfer Switch (ATS) is connected, it will cause the ATS to switch the load from line power to the Alpha FXM battery backup power.

11. Emergency Shutdown Procedure The Alpha FXM UPS contains more than one live circuit. In an emergency, line power may be disconnected at the UPS input, but AC power can still be present at the output. 1. Switch OFF the input circuit breaker. 2. Switch OFF the battery circuit breaker. 3. Disconnect the AC input power. 4. Disconnect the battery string.
Appendix A - Peukert Number and Battery Capacity A.1 Introduction The Alpha FXM series UPS units run on batteries when the AC utility power fails. In this mode, the user may want to estimate the remaining time that UPS batteries can supply power to the loads. The battery run time remaining is calculated based on the Peukert equation. Two critical parameters are required for the equation: • Peukert number. • Peukert capacity. The Peukert number and Peukert capacity depend on the battery characteristics.
A.4 Example The following example shows how to calculate Peukert’s number and capacity from a configured battery string. Consider four Alpha 195GXL batteries connected and configured as shown in the figure below. Two of the four batteries are connected in series, and the two series strings are connected in parallel to the 24 V DC output.

Appendix B - Types of Triggers There are 3 types of trigger: B.1 Edge trigger When the user input changes from one state to the other, the Alpha FXM is triggered to perform Action #1. If the level is set to High, the action will be triggered by a Low to High edge (leading edge). If the level is set to Low, the action will be triggered by the High to Low edge (falling edge).
Level Alternative When the level is set to High, the Alpha FXM is triggered to perform the next action when the user input changes from Low to High. If the input then changes from High to Low, no action will be triggered because the level is set to High. In other words, only a Low to High user input level triggers an action when Level is set to High. Similarly, when Level is set to Low, the Alpha FXM will trigger an action only with a High to Low user input.
