9 FXM HP Systems
This section provides a brief overview of the components and functions within a typical FXM HP system.
A basic FXM HP system usually consists of an FXM HP, a battery and a load, but can also include other
components.
9.1 Guidelines for Setting Up the FXM HP System
The following section contains basic guidelines for setting up the FXM HP system. System setup
consists of four parts: AC system inspection, battery inspection, setting up the system and testing the
system. System setup should only be conducted by a qualified technician.

REREQUISITE
:
Perform an inspection of the power system to confirm that the mechanical and electrical
requirements and parameters are within specification. Pay special attention to the battery to ensure it
is installed safely and correctly, and that the battery terminals are torqued to specification.
1. Make sure all power to the system is off.
2. Make sure the battery polarity is correct. Use a voltmeter if necessary to confirm.
3. Install the FXM HP.
4. Turn on the AC to the FXM HP and allow it to start up.
Verify that the system starts up, and the controller turns on.
5. Confirm the battery settings on the controller: capacity, charge limit, the Peukert exponent, etc.
6. Check that the battery polarity is correct and turn on the breaker for the batteries.
7. Follow the initial battery charge procedure as indicated in the manufacturer’s instructions.
The FXM HP system is operating normally. There may or may not be active alarms depending on
system configuration.
Perform tests to confirm that the system is operating properly. Specific tests to perform will depend on
the system configuration but may include:
• Correct AC input voltage and DC voltage
• Battery test
• Relay test
• Battery disconnect operation
• Alarm test
9.1.1 The System Mode
The System Mode indicates the state of the FXM HP. The mode can be observed in the System
Summary banner (if set as a preference) or on the System Status page.
In a system operating normally, the
System Mode will be Line . The Charging value will show Float
which indicates the battery is floating.
In a system that is charging, Charging Mode value either be
Bulk (battery is charging at constant
current) or Absorption (battery is in the absorption phase of charging).
