BEFORE CHARGING If the ampere capacity at the charging location is insufficient because other electrical appliances are being used, ask an electrical work contractor to provide an exclusive circuit for the charger. See the “On-vehicle Charger List” (page 2-2) for the AC power supply capacity.
Tap Changer 1.
Measure the power supply voltage to be used for charging. Tester range: AC (250 or 1000 V) Note: Measure the power supply voltage at night (or, if that is impossible, during a time when electrical appliances are not being operated).
2.
Set the tap changer. (1) Disconnect the battery plug. (2) Open the battery hood (3) Remove the controller panel cover. (4) Remove the tap cover of each phase corresponding to the power supply voltage measured in step 1 above. (5) Set the taps. (6) Connect the battery plug. (7) Connect the charger to the power supply outlet and press the NORMAL button. (8) Measure the voltage between the set taps. Tap 200 V 210 V 220 V
Measured voltage 199 V or less 200 to 209 V 210 to 219 V
Caution: After tap changer setting, if the error code “F6-2” is displayed during charging, change them to the upgraded ones. Note: • Taps are set to 220 V and 60 HZ at the time of shipment. • Be sure to set the tap changer for voltage and frequency change of phase U, V and W. • For about a week after tap changer setting, keep track of the battery charging state (specific gravity and electrolyte level) to make sure the tap setting is appropriate.
