OPERATING PRECAUTIONS
(1) Handling and installation
Handle according to the weight of the product.
Do not stack the inverter boxes higher than the number recommended.
Install according to instructions specified in this manual.
Do not open the cover during delivery.
Do not place heavy items on the inverter.
Check the inverter mounting orientation is correct.
Do not drop the inverter, or subject it to impact.
Follow your national electrical code for grounding. Recommended Ground impedance for
200 V Class is below 100 ohm and for 400V class below 10 ohm.
iG5A series contains ESD (Electrostatic Discharge) sensitive parts. Take protective
measures against ESD before touching the pcb for inspection or installation.
Use the inverter under the following environmental conditions:
- 10 ~ 50 ℃ (non-freezing)
90% RH or less (non-condensing)
Protected from corrosive gas, combustible gas,
oil mist or dust
Max. 1,000m above sea level, Max. 5.9m/sec
2
(0.6G) or less
(2) Wiring
Do not connect a power factor correction capacitor, surge suppressor, or RFI filter to the
output of the inverter.
The connection orientation of the output cables U, V, W to the motor will affect the
direction of rotation of the motor.
Incorrect terminal wiring could result in the equipment damage.
Reversing the polarity (+/-) of the terminals could damage the inverter.
Only authorized personnel familiar with LS inverter should perform wiring and
inspections.
Always install the inverter before wiring. Otherwise, you may get an electric shock or
have bodily injury.
(3) Trial run
Check all parameters during operation. Changing parameter values might be required
depending on the load.
Always apply permissible range of voltage to the each terminal as indicated in this
manual. Otherwise, it could lead to inverter damage.
