NOTE 9
：
If there is looseness at the connection between the fuse box and the INPUT cable, they may
produce heat and are burned. In addition, this leads to an open phase etc, causing unstable
operation of the power supply. Check the mounting state of the fuse box.
NOTE 10
：
Incomplete earth is very dangerous to the human body. Thoroughly check that the cable
connections are not loose or insufficiently long. For provisions on the earth, see Fig. 3.2.
NOTE 11
：
The EB power supply produces a high voltage inside and dust builds up on the part where the high
voltage is produced by the resulting dust collecting action. If a large amount of dust builds up, the
high voltage may leak. Therefore clean it periodically.
NOTE 12
：
The shielding and earthing of a high-voltage cable is very important process as a measure against
noise occurrence and safety. Any operation without this process may cause damage to the power
supply and very dangerous. So make sure that it is checked.
