connector. A matching power cord is included.
( 5 ) FUSE COMPARTMENT/VOLTAGE SELECTION: Before
plugging the unit into a power socket, please make sure
you have selected the correct voltage. Faulty fuses must
be replaced with fuses of appropriate rating without
exception. Some units feature a fuse compartment that
can be operated in two different positions, allowing
alternating between 230 V and 120 V. Attention: when using
the unit outside of Europe (running on 120 V), you have to
implement a fuse with a higher rating.
