3 .4 Connecting the CANNS500
See chapter 5, pages
to
for the various connection diagrams.
Keep the following order when connecting the device to the battery
bank. Ensure that all switches are turned off, all individual fuses are
disconnected (taken out), and the main battery bank minus is discon-
nected from the battery bank.
Step 1
• Connect the B1, B2, B3 and/or B4 to the CANNS500.

B1 should always be connected to the highest available voltage of
the battery bank. If four 12 V batteries are installed in series to make
a 48 V bank, then B1 is connected to the 48 V connection. B2 to 36 V,
and so on.
If two 24V batteries are installed in series to make a 48 V bank, then
B1 is 48 V, B2 is 24 V. If there is one battery bank casing (box) of 48 V
without individual battery blocks, then B1 is connected to 48 V.
In case of a lithium battery bank, connect the highest voltage to B1
only. Do not use B2, B3, B4.
For batteries connected in parallel, V1=V2. In this case, only connect
the plus of the battery bank to B+.
Step 2
• Connect the B1, B2, B3, B4 to the correct batteries.
Step 3
• Connect the shunt to the negative cable, in between the battery
bank and the system (the load: electric motor(s), consumer(s), bat-
tery charger(s), etc).
With the exception of the switch, make sure there is no equipment
between the CANNS500 minus and the minus of the battery bank.
Step 4
• Connect the "BATT" terminal of CANNS500 to the minus terminal
of the battery bank.
Step 5
• Place the individual fuses to connect B1 (plus B2, B3, B4 if appli-
cable).
• Operate the switch to connect the general minus to the system.
Power supply
The CANNS500 is powered via the Batt- shunt terminal and the B1+
terminal (spade connector, e.g. FASTON).
External temperature sensor inputs (T1-T4)
The external temperature sensor is used to accurately calculate
changes in battery capacity caused by temperature changes.
Two temperature sensors and cables (1 x 2 m and 1 x 5 m) are sup-
plied as standard. Supplement the sensor set with separately avail-
able sensor cables of the correct length.
• Connect the sensor plug to the two-pin connector labeled T1, T2
, T3 or T4.
• Stick or place the other end of the sensor cable on the individual
battery. Ensure that the sensor cap is placed away from the elec-
tric terminals.

NMEA2000 cable cover
The NMEA cable opening on the transparent cover must be cleared.
To do this, carefully break off the four parts by tapping them with a
screwdriver.
NMEA2000 compatible M12 connector
The M12 5-pin connector is compatible with NMEA2000 and has a
standard pinout.

Always follow the recommendations of NMEA2000 network
wiring but make sure to first connect B1 and the CANNS500 .
Always use a free T-connector in the NMEA2000 network to connect
the CANNS500 to via a NMEA2000 cable. Make sure that all connec-
tors are properly tightened to seal the metal contacts inside and to
prevent oxidation.
