[8] DISASSEMBLY AND ASSEMBLY

Before disassembly, be sure to disconnect the power cord
for safety.
1. Do not disconnect or connect the connector and the
harness while the machine is powered. Especially be
careful not to disconnect or connect the harness between
the MCU PWB and the LSU (MCU PWB: CN5) during the
machine is powered. (If it is disconnected or connected
during the machine is powered, the IC inside the LSU will
be destroyed.)
2. To disconnect the harness after turning on the power, be
sure to turn off the power and wait for at least 10 sec
before disconnection. (Note that a voltage still remains
immediately after turning off the power.)
