5.2.2 Wiring the Alpha FXM

WARNING!

Make sure the line power is off. Switch off all input and output circuit breakers on the

Alpha FXM before making any electrical connections.

If stranded wires are used to connect the input and output terminal blocks, ferules or

equivalent crimping terminals must be used.

5.2.3 Procedure

1. Connect the temperature sensor to the Alpha FXM (Batt Temp connector

). Attach the end of the battery

temperature sensor to the side of the centre battery.

2. If used, connect the following ports:

• Ethernet port

• RS-232 port

• Dry contacts

• User inputs

3. Connect the load to the Alpha FXM’s Output terminal block

. Torque to 1.4 N-m (12 lb-in).

4. Connect the line power to the Alpha FXM’s AC Input terminal block

. Torque to 1.4 N-m (12 lb-in).

WARNING!

Before proceeding, verify that the line wire is attached to the line terminal block, the

ground wire is attached to the ground terminal block, and the neutral wire is attached to

the neutral terminal block to prevent accidental shocks or electrocutions.

5. Connect the external batteries to the Battery connector

. Refer to “Wiring the external batteries”.

6. If needed, attach the terminal block covers and battery harness restraining bracket. See “Mounting the

Alpha FXM”.

5.3 UATS and (UGTS) Option

The Universal Automatic Transfer Switch (UATS) and Universal Generator Transfer Switch (UGTS) are the next

generation of Automatic Transfer Switch (ATS) and Generator Transfer Switch (GTS) products. They are optional

add-on switching units speciﬁcally designed for the FXM UPS family (FXM 650, 1100 and 2000) and the Micro

UPS family (Micro 300 and 1000). These switching units provide power and/or bypass capacity (automatic or

manual) so that the operator may safely disconnect the UPS from line or generator power for easy removal and

servicing. In bypass mode, the loads are directly connected to the line or generator power without any condition-

ing. Depending on the use of one and/or the other, the UATS/UGTS allows the use of up to 3 different back-up

sources (line, batteries and generator). Refer to the UATS/UGTS Installation Manual (Alpha P/N 020-165-B0) for

details.

WARNING!

Make sure you have read and understood the instructions given in the UATS/UGTS In-

stallation Manual before making any connection to the supply.
