◆ See “9-2-2. Adjusting the set voltage” and “9-2-3. Current setting” for details about how to set the internal voltage
and current.
If the standard board has been installed in the unit, the connectors (CN1, 2, 3), are arranged in the same way as shown in
the above figure.
The board features screwless connectors. Press the button of the connector and insert the cable (from which 10 mm
of the isolation coat has been stripped) into the hole on the left side of the button.
Use the AWG#24 - #28 cables (UL1007 stranded wire).
