f
To use key operating function for service and maintenance when installing module/group, set as main control or
cancel in module/group.
f
During Discharging mode, voltage of Inv1 and Inv2 will be displayed alternately.
f
Even when the power is off, it is dangerous when you come in contact with inverter PCB, fan PCB since high
pressure DC voltage is charged to those parts.
f
When replacing or repairing the PCB, cut-off the power and wait until the DC voltage is discharged before
replacing/repairing them.
- Wait for more than 15 minutes to allow those parts to be fully discharged.
f
When there is error, Discharge mode of DC link voltage may not have been effective. Especially when E464 and
E364 error is displayed, power element might be damaged so do not use the Discharge mode of DC link voltage.
