Note１) Refer to page 13 for the description of the display and key operation.
Note 2) Position of ⑩charge lamp depends on the model. Refer to page 11 for the details.
Note 3) Pay attention when operating by PC via ⑦RS422/RS485 port, as the operation can also be done from the panel of the inverter.
Note 4) Be sure to turn power OFF when connecting or disconnecting the operator such as OPE-SRmini,OPE-S,WOP to the ⑦RS422/RS485
port.

3. Cautions for installation

①Caution during transportation
Please pay attention when carrying the product as it is covered by a plastic case.
Especially, do not put pressure onto the front cover and terminal cover. Otherwise there is a risk of damaging the product.
Please do not use products that are damaged, and/or lacking components.
Dedicated operator for NE-S1 (NES1-OP) can be connected on this connector.
Push key for run, stop and reset operation.
Output terminal for intelligent relay (1 from c contact).
For connecting power supply, motor output and DC reactor.
Switch for integrated termination resistor (100Ω) for RS485.Integrated resistor of 100Ω is
connected when switched ON.
Changeover switch for RS422/RS485 communication setting.
Connector for RS485 external operator or PC software (RJ45 jack)
Voltage input (O) or current input (OI) can be selected using this switch.
Terminal for connecting input/output signals (digital/analog) for the inverter control.
Turns ON when the internal DC bus voltage is 45V or more.
In case of wiring, maintenance or else, please be sure to check that this lamp is turned OFF
after waiting 10 minutes of power OFF.
