    Do not touch the main p c board even when power is off, or damage may o ccur. .2 Product Inspection iDrive EDX inverters have all passed a full function test before delivery. Please check the following when you receive and unpack the inverter: The model and capacity of the inverter is the same as those specified on your order.

  • Page 7: Chapter 1 Safety Precautions

    Chapter 1 Safety Precautions Chapter 1 Safety Precautions 1.1 Operation Precautions 1.1.1 Before Power Up Caution The line voltage applied must comply with the inverter’s specified input voltage. Danger Make sure the main circuit connections are correct. L1(L), L2, and L3(N) are power-input terminals and must not be confused with T1, T2 and T3.

  • Page 8: During Power Up

    Make sure the model and capacity are the same as those set by b89. 1.1.4 Earth / ground leakage current Warning Warning ! iDrive EDX series built-in filter type can give leakage current > 3.5mA. ALWAYS ENSURE INVERTER IS CORRECTLY EARTHED / GROUNDED.. Operation with ungrounded supplies: DO NOT use iDrive EDX inverters on ungrounded (floating) power supplies.

  • Page 9: During Operation

    Chapter 1 Safety Precautions 1.1.5 During operation Danger Do not connect or disconnect the motor while inverter is operating the motor otherwise the inverter and/or the disconnecting device may be damaged by the high level of switch-off current. Danger To avoid electric shock, do not remove the front cover when power is on. After a power-loss trip (under-volt) trip occurs, the motor will restart automatically when power is restored if auto-restart function is set.

    Chapter 5 Trouble shooting and maintenance 5.4 Routine periodic checks To ensure stable and safe operation, check and maintain the inverter regularly. The table below lists the items requiring checking to ensure safe operation. Check these items 5 minutes after the “Charge” indicator goes out to prevent service persons from being hurt by residual electric power.
