【Config Set】
Turn OFF the circuit breaker after changing the setting.
Press the key after select “OFF”
Select “Type 2”
Select“INV Board Setting”
Added the setting for the inverter board in Config set only if Controller Model had been selected as “DECOSV” in order to the controller recognizes which inverter board type is installed on LX10F**A model.
If “Controller Mode” had been selected as “DECOSVa”(Type B) , INV Board Setting is not appeared in Config set.(DECOSVa should have B type inverter board. not accept to install A type).
When new Inverter board replacement, software and initial settings must be changed.
Problems occur in operation of container unit if setting is incorrect.

Precautions
5
Danger
Caution• Cut extra length of cable ties so that the cut end does not form a dangerous edge.
• Since the removed bolts will be reused, keep them in such a manner that they are not
confused with each other.
• Prepare 400 V power supply that will be needed for check after completion of the work.
• Before starting the work, turn off the circuit breaker, unplug the power cable, and wait for
more than ten minutes until the electric charge stored in the capacitors on the INV board
is discharged.
• Start the replacement work after confirming by a tester that the voltage between the
terminals P2 and N on the INV board on the right side inside the INVBOX is DC 50 V or
lower.
