2. Install the current sensor (Fig. 1 pos ) between
the midmost cells. See
The current sensor’s outer cable lug should be
fitted to the nearest cell’s negative terminal
(nearest battery’s positive terminal).
Warning
Risk of short-circuiting!
High voltage!
The current sensor should be fitted between
two different cells. If the current sensor is
connected on the same cell there will be a
short-circuit, which can result in damage to the
battery, heat development and fire.
Warning
Fire hazard!
Incorrect use can lead to heat development
and fire.
The current sensor has a limited current
capacity.
Maximum continuous charging current is 150 A
for 35 mm
2
and 260 A for 70 mm
2
.
Ensure that these levels are not exceeded.
3. Installation of Access™ BMU (Fig. 1):
• Install the battery monitoring unit and its
cables in a dry place on the battery.
• Make sure there is no risk of mechanical
damage.
• The battery monitoring unit is installed so the
control panel is fully visible.
4. Connect the battery monitoring unit’s black
cable (Fig. 1 pos ) to the battery’s negative
terminal (Fig. 1 pos ).
5
Locate where the electrolyte level and battery
temperature sensor is to be installed.
Note:
This sensor may only be used on vented
batteries.
The electrolyte level and battery temperature
sensor (Fig. 1 pos ) must be installed at least
± 3 cells from the current sensor’s connection
point in order for the sensor to work correctly.
6
Drill a 12 mm (0.472 inch) hole in the top of the
battery cell for the electrolyte level and battery
temperature sensor.
7
Fit the sensor’s seal (Fig. 3 pos ).
8
Cut the sensor’s lead probe (Fig. 3 pos ) and
the plastic casing so that the sensor gives an
alarm well in advance of the water reaching a
critical level for the battery. The cut must be
diagonal so that there is a sharp pouring edge.
If the electrolyte level is (Fig. 3 pos ) below the
lead probe the low electrolyte level indicator
comes on
.
The battery’s lead plates (Fig. 3 pos ) must be
covered with electrolyte.
Warning
Risk of short-circuiting!
High voltage!
Make sure that the electrolyte level and battery
temperature sensor is not in contact with the
battery’s lead plates. This can result in short-
circuiting and incorrect status indication.
9
Install the electrolyte level and battery
temperature sensor. Makes sure the seal
closes tightly against the hole.
10 Connect the battery monitoring unit’s red cable
(Fig. 1 pos ) to the battery’s positive terminal
(Fig. 1 pos ).
All indications on the battery monitoring unit’s
control panel come on briefly.
11 Check and rectify any indications. Indications
are described in
12 Secure Access™ BMU and its cables using the
supplied cable ties.
13 Check that all the battery’s soldered joints are
correct.
Warning
Risk of fire!
A poorly soldered joint can damage the battery,
resulting in heat development and fire.
Check all soldered joints.
