Connecting the DUT (Battery)
We recommend that you install a fuse between the PFX2512 and DUT (battery) to allow safe
connection between them and to prevent short-circuit accidents in DUT cables and voltage
sensing cables. Insert the fuse as close to the DUT (battery) terminal section as possible.
WARNING
Risk of electric shock.
• After connecting the devices, connect the PFX2512 to the DUT (battery). Connect the
PFX2512 side first.
• When installing a fuse between the PFX2512 and DUT (battery), be sure to turn off the
POWER switch, and turn off the circuit breaker of distribution.
CAUTION
Be sure to connect the voltage sensing cable.
The system will not work properly if it is not connected. Moreover, make sure to connect the cable
close to the DUT (battery). Performing a charge/discharge test without connecting the voltage
sensing cable may damage the DUT (battery) and is extremely dangerous.
Connect the DUT (battery) after turning on the power switch.
If there is a problem, the warning function ( p. 70 ) can prevent failure from occurring.

CAUTION
• A fuse blowing may lead to explosions or fire. Be sure to put a cover on the fuse.
• Use DC fuses that have sufficient breaking capacity.
