8-2. Reassembly
Reassembly can be accomplished by following the disassembly procedures in reverse. However, particular
attention should be given to the following points.
(1) Solder the lead wires of the Cord [10] after passing their stripped end portions through the holes of the Printed
Circuit Board [4] and bending them securely.
(2) Be very careful to ensure that the lead wires are not pinched between Case (A) and Case (B) during
reassembly.
8-3. Confirmation after Reassembly
On completion of reassembly, confirm the following items.
(1) Confirmation of Charging State
Confirm that the Pilot Lamp on the Charger goes on.
Confirm that the Pilot Lamp goes off approximately 60 minutes after the start of charging (when FEB 9S is
charged at 20 ˚C (68 ˚F)).
(2) Measure the Insulation Resistance and Conduct a Dielectric Strength Test
Insulation Resistance: 10 megohms or more between the plug blade of Cord and the Nameplate or fastening
screws on the Case with DC 500 V Megohm Tester.
Dielectric Strength Test:
(a) Between the plug blade of the Cord and charging terminal blade
(b) Between the plug blade of the Cord and Nameplate or fastening screws on the Case
The dielectric strength test should be conducted at the following voltage:
Nameplate Test voltage
110, 120, 220, 230, 240 V AC 1,250 V (1 minute)
