OTHER PRECAUTIONS
(1) Handling and installation
 Handle according to 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.
 The inverter is precise equipment. So do not drop the inverter or subject it to impact.
 Follow your national electrical code for grounding. Recommended ground impedance for 230V
Drives is below 100 ohm and for 415V class below 10 ohm.
 This series inverter contains ESD sensitive parts. Take protective measures against ESD
before touching the PCB for inspection or installation.

(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.
 Wrong connection of input terminal (R, S, T) and output terminal (U, V, W) will damage the
inverter.
 Only authorized personnel familiar with L&T inverter should perform wiring and inspections.

Always install the inverter before wiring. Otherwise, you may get an electric shock or have bodily
injury.
