Starter battery:
Typically 55Ah to 100Ah for automotive applications.
A start battery should never be deeply discharged
Service battery:
Size 28Ah to 800Ah.
Batteries are connected in parallel to increase capacity
(Ah).
Suitable deep cycle batteries should be used.
SMARTPASS 120:
Install according to instruction manual.
Start assistance.
SMARTPASS 120 automatically connects the service
battery to the starter battery to
assist, if the starter battery on its own is unable to start
the engine. After the start assistance function
has been activated, SMARTPASS 120 will display a fault
indication until starting has been
achieved without using the start assistance function.
Fuses:
If fuses are used, mount the fuses as close to each
battery as possible.
Suitable fuse size:
D250SA: 30A
D250SA and SMARTPASS 120: 300A
Please verify directive for applicable installation
regarding fuses.
Consumers:
Critical consumers are connected directly to the service
battery bank. A critical consumer could be VHF radio.
Non critical consumers are connected directly to the
consumer output terminal at SMARTPASS 120. If battery
voltage reach a critical low level, the consumer output
terminal is deactivated to protect the Service battery.
Non critical consumers receive current from the
alternator instead of the Service battery during drivning,
to make the charing of the Service battery faster
Temperature sensor:
Attach the temperature sensor onto the service battery.
Wiring:
Please see instruction manual for suitable dimensions.
Please verify directive for applicable installation
regarding wiring.
A thick wire generate less voltage drop than a thinner
wire at high current.

Select a charger that is suitable regarding the capacity of
the battery bank and also the requirement of recharge
time. A typical charger is MXS25 or M300.
