J Maintenance and Inspection
WARNING
Page
D Do not touch the Inverter Panel terminals. Some of the terminals carry high voltages
and are extremely dangerous.
Touching the terminals can result in electric shock.
10 - 2
D Always have the protective cover in place when power is being supplied to the Invert-
er. When attaching the cover, always turn OFF power to the Inverter through the
MCCB.
Doing so can result in electric shock.
10 - 2
D After turning OFF the main circuit power supply, wait until the CHARGE indicator light
goes out before performance maintenance or inspections.
The capacitor will remain charged and is dangerous.
10 - 2
D Maintenance, inspection, and replacement of parts must be performed only by autho-
rized personnel.
Remove all metal objects, such as watches and rings, before starting work. Always
use grounded tools.
Failure to heed these warning can result in electric shock.
10 - 2
D Before mounting or dismounting a Module, make sure that the main circuit and control
power supply have been turned OFF.
Not doing so can result in electric shock.
10 - 6
D Do not dismount a Module until the CHARGE lamp on the Module turns OFF after turn-
ing OFF the power supply.
An electric shock may occur is the Module is dismounted while still charged.
10 - 6
D Use special lifts for mounting or dismounting a Module.
Not doing so can result in injury.
10 - 6
D The Modules are heavy, and mounting or dismounting the Modules must be per-
formed by three workers: One to operate the lift and two others for mounting and dis-
mounting the Modules.
Not doing so can result in injury
10 - 6
D Before disposing of a Module, open a hole in the heat sink attached to the Module to
purge gas.
Exposing the heat sink to a high temperature without opening a hole in the heat sink can result in
explosion and injury.
10 - 14
CAUTION

D A CMOS IC is used in the control board. Handle the control board and CMOS IC care-
fully. The CMOS IC can be destroyed by static electricity if touched directly.
The CMOS IC can be destroyed by static electricity if touched directly.
10 - 2
D Do not change the wiring, or remove connectors or the Digital Operator, during opera-
tion.
Performing this word during operation can result in personal injury.
10 - 2
J Others
WARNING
D Do not attempt to modify or alter the Inverter.
Alterations or modifications can result in electrical shock or injury.
