Ensure that all loads and generators are switched off
Disconnect the NEGATIVE terminal from the battery and
connect it to the shunt as shown in Figure 1.
Connect the Black and White wires and Yellow wire
to the shunt as shown on Figure 1.
Connect the short link cable to the shunt and then to the
negative terminal of the battery, as shown on Figure 1.
Ensure it is positioned where it cannot come into electrical
contact with other parts, and ensure it will remain dry and
free from contaminants. Also note that the shunt can get
warm when heavy currents flow, so ensure it is secured in
a position where its heat cannot affect other parts.
TAKE CARE TO AVOID OVER-TIGHTENING THE
CONNECTIONS TO THE SHUNT..
Finally, connect the red wire to the POSITIVE terminal of the
battery to complete the electrical installation. The BM-1 Compact
will now begin assessing the battery state, using its factory
default values. The default values must be set to the values
appropriate to the new installation as discussed in
SETTING UP, below.
Do NOT put the battery on charge immediately.
Apply a load to the battery by switching on lights or instruments
and wait for a few minutes for the BM-1 Compact to “learn”
the battery's characteristics and to show a steady reading
before starting charging.
It is necessary to set the battery capacity to the correct value,
and may be necessary to calibrate the zero current setting,
as described in SETTING UP, below.

NORMAL OPERATION
The BM-1
Compact
offers two normal modes of operation:
Time to go.
Volts and Amps;
The battery charge state is always displayed on the scale on the right
of the display. If the battery voltage falls below the preset alarm level
representing dangerous discharge, the alarm bell symbol is flashed.
