Access™ BMU -
Instruction for use
General
Access™ BMU is designed for monitoring vented
lead-acid batteries. The unit is mounted on the
battery and monitors current, voltage, temperature,
electrolyte level and voltage balance.
The functions in Access™ BMU are activated,
deactivated and adapted using the PC software
Access™ Service tool.
Access™ BMU is permanently mounted on the
battery or used as a temporary instrument for
troubleshooting or operating analysis.
When using Access™ BMU together with the
Access™ battery charger, the battery charger is
sent battery specific parameters from the battery
monitoring unit for optimal charging of the battery.
The status of the battery can be read on the
charger’s display.
Information about the charging and discharging
process, the battery status and deviations are
stored internally in the unit. Access™ BMU
communicates wirelessly with other Access™
units.
Information concerning the product’s part number,
serial number and rating can be found on the rear
of the unit.

Installation
Warning
Electrolyte is corrosive!
If electrolyte comes into contact with the eye,
damage can occur very quickly.
Rinse the eye immediately and thoroughly for at
least 10 minutes, seek medical attention.
Wear protective equipment such as safety glasses
and gloves to avoid contact with the electrolyte.
Note:
Installation may only be performed by qualified
installers.
Follow the battery supplier’s instructions for
handling batteries.
Access™ BMU is solely designed for use with
lead-acid batteries up to 96 V nominal DC voltage.
Consult the manufacturer regarding all other
usage.
Ensure that the Access™ BMU is installed by a
qualified installer in accordance with the
instructions.
Access™ BMU must be well protected against
mechanical damage during daily use, servicing
and maintenance.
Instructions
A threaded insert must be installed to connect
Access™ BMU on the lead terminals of the battery
and cells.
Installation of the threaded inserts
1. Drill a 5.5 mm (0.219 inch) hole in the
appropriate lead terminal. The depth of the hole
must be at least 7.7 mm (0.302 inch).
2. Knock the supplied threaded insert into the
hole.
Now secure the cable lug, use the supplied
washers and screws.
Installation of BMU
1. Locate the battery’s two midmost cells.
The current sensor must be attach between
these cells.
Example: On a 24 V battery it is cells 6 and 7.
4

ENGLISH
2. Install the current sensor (Fig. 1 pos ) between
the midmost cells. See Installation of the
threaded inserts.
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 mm2and 260 A for 70 mm2.
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 Status indicator.
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.
