1. Shut down electric power before maintenance.
Maintenance while power is active may cause electric shock.
2. Immediately after the driver is powered off, do not touch any
terminal.
The driver contains electricity inside also after being powered off.
To avoid electric shock, do not touch any terminal until the charge voltage monitor LED
goes out on the display panel after being powered off.
3. Do not perform insulation resistance or high voltage breakdown
tests.
The test causes damage to the HA-520 driver circuit that results in abnormal motion.
