CT100G Series Inverter Safety precautions

- 3 -

» Keep the signal cables of the inverter away from the power cables as far as

possible, or distribute the two categories of cables vertically-crossed if the

distance is not far enough, otherwise it may cause signal interference.

» Ensure that all the screws are tightened when wiring, otherwise damage to

the inverter may occur.

» The encoders and sensors should be applied with the shielded cables and

the shielded layer should be grounded reliably.

Operation

» Confirm that the wiring is completed and correct and then cover the plate

before power on.

» Do not open the plate after power on, otherwise electric shock may occur.

» Operate the inverter appropriately, otherwise damage to the inverter may

occur.

» Non-professionals are not allowed to test the signals when the inverter is

running. Otherwise, physical injury or damage to the devices may occur.

» Do not change the parameters of the inverter at random, otherwise damage

to the inverter may occur.

» Do not touch the fans and brake resistors, otherwise it may cause

mechanical injury or burn.

» Do not start up or stop the inverter by power on or off, otherwise damage to

the inverter may occur.

» Ensure that the circuit breakers or contactors at the output sides of the

inverter are not in output state before switching, otherwise damage to the

inverter may occur.
