Hints for DC power connection:
The DC power source should be able to be switched off and on via an isolating switch.
The M@CII 70/104/121/150 system is only completely disconnected from the DC main power source,
when the DC power cord is disconnected either from the power source or the unit. Therefore, the DC
power cord and its connectors must always remain easily accessible.
Hints for AC power connection via external AC/DC adapter:
If the M@CII 70/104/121/150 system is connected to an AC power source via an AC/DC adapter, the
main power cable of the external AC/DC adapter serves as disconnecting device. For this reason the
outlet of the AC power source must be located near to the device and be easily accessible.
