Installing Alternate AC Plug on the Battery
Charger
In most cases the 2020ppbPRO will be shipped with an AC line cord that will fit the
AC wall outlet in your area. If this cannot be done, you may need to obtain an AC
line cord suitable for the AC receptacle in your area.
The AC line cord, attached plug and receptacle must be marked with your country’s
certification mark and the cord must have a Harmonization (HAR) mark.
The line cord must be rated for either 100 to 120 VAC at 60 Hz or 220 to 240 VAC at
50 Hz. The voltage rating will depend on the voltage in your area.
Contact your INFICON representative to obtain more information.
