1-2 Precautions
To ensure safe operation of the 3G3EV, note the following items:
H
Always Hold the Heat Sink During Removal
When moving the 3G3EV, always hold the heat sink (aluminum portion on the rear of the Unit).
Heat sink
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 damage the equip-
ment.
H
Do Not Conduct a Dielectric Strength Test
Because the 3G3EV Inverter is an electronic control unit using semiconductor, never conduct a dielec-
tric 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 and the
User’s Manual.
