INTRODUCTION AND SPECIAL NOTES
The LINK 2000 is an integrated battery monitor and inverter/charger control. It displays
the critical information necessary for 12 V or 24 VDC system battery management and
allows precise control of critical inverter and charger features. The Link 2000-R comes with
an additional manual describing the Ideal Regulator option. The LINK 2000 may be used
as a stand-alone battery monitor or with the following inverter/chargers:
FREEDOM 10, 15, 20, 25, and 30
In order to understand, use, and install the LINK 2000, PLEASE read this manual! It
is as short as possible and provides important information. For installation, operation,
or warranty questions, please call Xantrex.
The following Important Special Notes contain cautions and special considerations that
must be considered during the installation of the LINK 2000. Failure to read and follow these
special notes can lead to damage of the LINK 2000, the inverter, or other electrical equipment.
The Helping Hand is used to draw your attention to very important sections of this
manual or to indicate items that may need to be changed through the SETUP routine. Please
take the time to read these sections.
1) DO NOT DISCONNECT THE NEGATIVE BATTERY CABLE TO THE
FREEDOM WITH THE INVERTER OR CHARGER TURNED ON! WHEN
INSTALLING, CONNECT THE INVERTER CABLES
BEFORE PLUGGING
THE REMOTE CABLE INTO THE LINK 2000. UNPLUG THE REMOTE
CABLE BEFORE THE FREEDOM INVERTER IS DISCONNECTED FROM
THE BATTERY.
2) Turn the ON/OFF switch located on the inverter to the OFF position.
3) When used in a mixed voltage (12 V and 24 V) system, Battery #1 is the battery that the
LINK 2000 uses for voltage regulation. Make sure it is the battery that is used by the inverter/
charger, or with the alternator regulator option it must be the battery being charged by the
alternator. See Functions Mode F11 on page 13.
BASIC BATTERY FACTS
1) One amp-hour (Ah) is 1 amp for one hour, or 2 amps for 1/2 hour, or 4 amps for 1/4 hour, and
so on.
2) A liquid battery is generally considered completely discharged when the battery voltage
reaches 10.5 volts for a 12 volt battery.
3) Batteries for cycling service are normally rated with a) a 20-hour discharge rate which
means, for example, a 100 Ah battery will sustain 5 amps for 20 hours, and b) a reserve
capacity stated in minutes for a 25-amp discharge rate.
4) Our Mid-Capacity Rule says that discharge below 50% shortens battery life and charging
more than 85% takes too long with an engine-driven charging system. So, 35% of the battery
capacity is all that is normally available.
