7. DISASSEMBLY
1. Discharging
(1) Unplug the power cord.
(2) Connect D5301 B+ and B- terminals, using resistor leads with 47 - 100 ohms (2 W or higher), for discharging.
∗
Discharging time: 30 - 60 seconds, depending on the level of resistance.
(3) Check that the voltage between the B+ and G
N
D terminals, as well as that between the B- and G
N
D terminals, is less
than
1
V
, using a tester.
∗
Be sure to connect the G
N
D terminal of the tester to the chassis.
∗
If the voltage is still 1
V
or higher, repeat Step (2).
