H Watch Out for Residual Voltage On Charged Portions
After the power is turned off, residual voltage remains in the capacitor inside the
Inverter. Therefore, touching terminals immediately after turning the power off may
cause an electrical shock.
If an inspection or some other task is to be performed, always wait at least one minute
from the time all indicators on the front panel go off.
(Note that this warning is applicable whenever you perform any task after turning the
main circuit off.)
H Do Not Remove the Digital Operator When the Main Circuit is
Still On.
Always turn the main circuit off before removing the Digital Operator.
Removing the Digital Operator with the main circuit ON may cause an electrical shock
and damage the equipment.
H Do Not Modify Wiring or Check Signals When the Main Circuit
is On.
Always turn the main circuit off before modifying wiring or checking signals.
Touching terminals while the main circuit is on may cause an electrical shock and dam-
age the equipment.
H Do Not Conduct a Dielectric Strength Test.
Because the 3G3EV Inverter is an electronic control unit using semiconductor, never
conduct a dielectric strength test or an insulation resistance test for the control circuit.
H Modify Constant Settings Correctly.
Always modify the constant settings according to the procedures described in this
manual.
