Varta EASY BLADE - Push Button; LED Indications

15
A system without CAN communication to the Host needs two CAN termination resistors of 120 Ohm
each. One CAN termination resistor has to be connected to the M12 connector of the first module and
one CAN termination resistor has to be connected to the M12 connector of the last module. In this way
the resistors are placed at the physical ends of the CAN bus.
Systems with CAN communication to the Host only need to have one CAN termination resistor of 120
Ohm on the last module which is connected. In this case the Host needs its own termination resistor.
Please make sure that the system is terminated at both physical ends of the CAN Bus!
d. Charger
We recommend VARTA approved chargers which are already programmed with compatible firmware
and tested. The charger datasheets can be provided on request. (for more information on charging
see chapter 10).
