2.4.2 Connection to output terminals
The outputs are insulated between the power supply inputs. The “Lo” output terminal is connected to
the chassis.
For the connection to the output terminals, use a cable that is resistant to a maximum output current of

30 A, and a round crimp terminal with a sleeve.
For the wiring to the load, use a wire that is as thick as possible, twisting the wire together so that it
does not form a loop, and not making it any longer than necessary.

Note that since the “Lo” output terminal of the BP4620 is connected to the chassis, it is not possible to
connect multiple outputs of the BP4620 in series.
Also, do not connect a grounded load or measuring instrument whose input block is grounded to the
output terminal of the BP4620, as this may cause some of the output current to leak to the protective
grounding wire of the power supply and have an unpredictable effect on the load or measuring
instrument as shown in Figure 2-4.
During output, absolutely never touch the output terminals.
For safety’s sake, be sure to use the BP4620 with the supplied pin covers mounted.
To reduce the risk of electric shock and the contact between the terminals, use a round crimp terminal
with a sleeve for the connection to the output terminals.
