Confirmation After Reassembly - Hitachi UC 18YML2 Technical Data And Service Manual

9-3. Confirmation after Reassembly

(1) Confirm the following after reassembly. The red pilot lamp on the charger lights up when
charging is started.
When charging the BSL 1430/BSL 1830 Batteries, confirm that the red pilot lamp flashes at
•
one-second intervals about 45 minutes after the start of charging.
(2) Measure the insulation resistance and conduct a dielectric strength test.
Insulation resistance: 10 M
•
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 fastening screws on the case
Conduct a dielectric strength test based on the voltage listed on the nameplate.
Voltage on the nameplate
CAUTION: Without fail, insulation resistance must be measured between the plug blade of
the cord and the nameplate or fastening screws, and a dielectric strength test
must be conducted between the plug blade of the cord and the charging
terminal blade or between the plug blade of the cord and the nameplate or
fastening screws on the case. Under no circumstances should testing be
conducted between both blades of the plug or those of the charging terminal.
Doing so may cause the charger to burn out.
