    • Do not perform a withstand voltage test on any part of the Inverter. This electronic equipment uses semiconductors and is vulnerable to high voltage. • Do not remove the Digital Operator or the blank cover unless the power supply is turned OFF. Never touch the printed control board (PCB) while the power supply is turned ON.

  • Page 12

    • Set the parameter according to the motor. • If a single Inverter is connected to more than one motor, set the parameter to 2 for no protection. The parameter is also disabled by setting n32 for rated motor current to 0.0. Provide thermal relays or other methods separately for each motor to protect equipment from overloads.

    Ambient temperature for operation (panel-mounting): –10°C to 50°C Humidity: 95% or less (no condensation) • Install the Inverter in a clean location free from oil mist and dust. Alternatively, install it in a totally en- closed panel that is completely protected from floating dust.

  • Page 17

    • To enhance operation reliability, the Inverter should be installed in an environment free from extreme temperature changes. • If the Inverter is installed in an enclosed environment such as a box, use a cooling fan or air conditioner to maintain the internal air temperature below 50°C.

    The 3G3IV-PJVOP140 and 3G3IV-PJOP146 Digital Operators contain an EEPROM. All Inverter parameter settings, the Inverter capacity, and the software number are re- corded in this EEPROM. The EEPROM can be used to copy parameter settings to other Inverters. Parameter settings can be copied between Inverters with the same power supply speci- fications, but some of the parameter settings are not copied.
