3.4.3 Power Supply Guidance
The NV9 Range of products require a stable 12V DC power supply. Please check the
power requirements of your host machine and other peripherals to dimension a
suitable power environment for your machine setup.
TDK Lambda manufactures suitable power supplies. Please see table below for
further details.

3.6 Reliability Data
The below data refers to the Mean Cycles Between Failure (MCBF) and the Mean
Cycles Between Intervention (MCBI). The difference between the two is that a
failure would usually require the unit being replaced. Whereas an intervention would
be an issue that is easily clearable such as a reset or clearing a note path jam.
A cycle is classed as a note or ticket being either accepted or dispensed. For
example; if a unit accepts a note and then dispenses a note as change, it is classed
as two cycles.

MCBF: 200,000 Cycles
MCBI: 100,000 Cycles
It is important to note that when adding a recycler or printer, you are doubling the
number of modules. Thus, the MCBF/MCBI will naturally be halved.
