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 Ass'y [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 EB 1812S 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 the charging terminal blade
(b) Between the plug blade of the cord and the nameplate or the fastening screws on the case
The dielectric strength test should be conducted at the following voltage:
Voltage on the nameplate Test voltage
120 V AC 1,240 V (1 minute)
(CAUTION) Measurement of insulation resistance and the dielectric strength test must be conducted
between the plug blade and the nameplate or fastening screws on the case, and between the
plug blade and the charging terminal blade. Under no circumstances should tests be
conducted between both blades of the plug, or both blades of the charging terminal, which
may cause burnout of the charger.
