Basic Installation Procedures
1. Select the battery to be monitored. The BTS should be
connected to the battery bank that is directly connected to
the Freedom EX 4000.
2. Switch off all devices operating from the battery, or open
the battery switch (if present) to disconnect the battery.
3. Wait ten minutes for any explosive battery gases to
dissipate.
4. Select a side suitable for attaching the sensor.

5. The surface where the sensor is to be mounted must be
flat and free from reinforcing ribs or other raised features.
This surface must be in direct internal contact with the
battery electrolyte. Do not install the sensor near the top of
the battery or on the battery's top surface.
6. Clean the selected area thoroughly to remove any oil or
grease that could prevent the sensor from adhering to the
battery case. Allow the battery case to dry thoroughly.
7. Peel the protective backing from the self-adhesive strip on
the rear of the sensor.
8. Press the sensor firmly against the clean side of the
battery to fix it in place, as shown in Connecting to the
BTS Port.
9. Route the sensor cable to the Freedom EX 4000 and plug
it into the BTS port. Secure the cable along its length.

Connecting to ACC Signal
With the Communications and Control 20-pin Harness (see
Figure 24 on page 37), the Freedom EX 4000 can be wired to
inhibit inverter operation in the absence of a vehicle's (or
vessel's) +12VDC ignition control signal. This feature can avoid
unnecessary battery drain that would otherwise occur if the
inverter/charger/converter was operated without a charging
source such as the vehicle alternator.
1. Ensure that AC and DC power are both OFF.
2. Ensure the vehicle's (or vessel's) ignition is turned to OFF
position. It is highly recommended to remove battery
power by disconnecting the vehicle's battery cables.
Refer to the vehicle's (or vessel's) user manual for proper
instructions on how to disconnect the battery cables.
3. Locate the vehicle's (or vessel's) ignition control wire from
its ignition circuit. This wire must be fused appropriately at
no more than 5 A. Refer to the its user manual for
guidance.
Description of Ignition Control Features
For information about the features and instructions on changing
the ignition control features, see Configuration on page 1.
Table 6 Ignition Control Features
This setting allows the
inverter/charger/converter to operate
(Battery mode) automatically when an
ignition control wire is connected to the
Ignition Auto-
ACC input via pin 2 of the
on (ATO)
Communications and Control 20-pin
Harness and a valid ignition signal is
constantly detected. The inverter works in
tandem with the vehicle's ignition circuit.
This setting allows the inverter to operate
(Battery mode) when an ignition control
wire is connected to the ACC input
terminal via pin 2 of the Communications
Ignition Lock-
and Control 20-pin Harness and a valid
out (LOt)
ignition signal is constantly detected.
When enabled, you have to manually
press the Power button on the display
panel to operate the inverter.
To completely disable the ignition control
features do the following:
Off (OFF)
Set Ignition Control to Off (OFF) using the
Select buttons on the Display panel.
