※
When pcb will be replaced or repaired , please shut off the power after carrying out discharge mode without fail
※
When discharge mode is progressing, DC voltage of inverter PBA 1 & inventer PBA 2 indicate on display alternately.
If LED display of inverter PBA 1 & inventer PBA 2 will be turned off and "OK" is displayed, a discharge is completed.
※
If INV error is occurred(E464/364, E461/361, etc.), please wait more than 15 minutes until self-discharging after shutting off the power
because it can not enter a discharge mode.
※
If normal completion discharge mode or self-discharge will be not completed, it is very dangerous to contact because a high DC voltage of
inverter PBA is charged.
