1. SJ-FB (Feed back board)
2. Instruction manual
3. Board bind screws (M3×8mm)
Please contact where you bought the unit as soon as possible when there is any prob-
lem.
1.2 Inquiry and Warranty of the Unit
1.2.1 Request upon inquiry
If you have any questions regarding damage of the unit, unknown parts or for general
inquiries please contact your supplier or the local Hitachi Distributor with the following
information.
(1) Inverter Model
(2) Production Number (MFG, NO)
(3) Date of Purchase
(4) Reason for Calling
Damaged part and its condition etc.
Unknown parts and their contents etc.
1.2.2 Warranty of the unit
The warranty period of the unit is shown below.
ü 1 year after normal installation.
However within the warranty period, the warranty will be void if the fault is due to;
(1) Incorrect use as directed in this manual, or attempted repair by unauthorized
personnel.
(2) Any damage sustained, other than from transportation (which should be re-
ported immediately).
(3) Using the unit beyond the limits of the specification.
(4) Act of God (Natural Disasters: Earthquakes, Lightning, etc)
The warranty is for the inverter only, any damage caused to third party equipment by
malfunction of the inverter is not covered by the warranty.
Any examination or repair after the warranty period (one year) is not covered. And
within the warranty period any repair and examination which results in information
showing the fault was caused by any of the items mentioned above,. the repair and ex-
amination cost are not covered. If you have any questions regarding the warranty
please contact either your supplier or the local Hitachi Distributor. Please refer to the
back cover for a list of the local Hitachi Distributors.
