Cautions about cleaning
To clean the inverter, wipe dirt off only its surface with a soft cloth but do not try to remove dirt or stains from any
other part. If stubborn stains persist, remove them by wiping gently with a cloth dampened with neutral detergent
or ethanol.
Never use any of the chemicals in the table below; the use of any of them may damage or peel the coating away
from molded parts (such as plastic covers and units) of the inverter.
Acetone Ethylene chloride Tetrachloroethane
Benzen Ethyl acetate Trichloroethylene
Chloroform Glycerin Xylene
14.2 Periodical inspection
Make a periodical inspection at intervals of 3 to 6 months depending on the operating conditions.
Warning
Mandatory
action
Before inspection, perform the following steps.
(1) Shut off all input power to the inverter.
(2) Wait at least 15 minutes and check to make sure that the charge lamp is no longer lit.
(3) Use a tester that can measure DC voltages (400V/800V DC or more), and check that the voltage to
the DC main circuits (across PA/+ - PC/-) does not exceed 45V.
Performing an inspection without carrying out these steps first could lead to electric shock.
Prohibited
Do not replace parts.
This could be a cause of electric shock, fire and bodily injury. To replace parts, call your Toshiba
distributor.
