8.1 Safety precautions

Before the commissioning, observe the following warnings and instructions:

Commissioning 8.2 Sequence of operation

1Read and follow the safety precautions

2After installation ensure that:

-the frequency converter and motor are connected to ground.

-the mains and motor cables are comply with the installation

and connection instructions (chapter 6.1).

-control cables are located as far as possible from the power cables

(table 6.1.4-1), shields of the control cables are connected

to the protective earth and wires do not have contact with any electri-

cal components in the device.

-the common input of digital input groups is connected to +24 V or

ground of the I/O-terminal or external supply

3Check the quantity and quality of the cooling air (chapters 5.1 and 5.2).

4Check that moisture has not condensed inside the frequency converter.

5Check that all Start/stop switches connected to the I/O terminals are in Stop position.6Connect the Vacon frequency converter to the mains and switch the power ON.7Ensure that the parameters of the Group 1 match the application.

Set the following parameters to match the motor nameplate:

- nominal voltage of the motor

- nominal frequency of the motor

- nominal speed of the motor

- nominal current of the motor

- supply voltage

See values on the rating plate of the motor.

8Start-up test without the motor

Make either test A or B:

A Controls from the I/O terminals:

-turn Start/Stop switch to ON position

-change the frequency reference

-check in the control panel's Monitoring menu that the

output frequency follows the frequency reference

-turn Start/Stop switch to position OFF

B Controls from the Control Panel:

-change controls from the I/O terminals to the Control Panel with

the programmable button #2, see Chapter 7.6.

-push the Start button

-go to the Reference menu and change the frequency reference

with the buttons , see Chapter 7.5

-go to the Monitoring menu and check that the output frequency

follows the reference, see Chapter 7.3.

-push the Stop button

If the inverter has to be tested on a motor connected to the process, ensure it is safe to be powered up. Inform your co-workers about the tests.

-switch the mains OFF and wait until the Vacon frequency converter

has powered down according to Chapter 8.1/ point 4

-connect the motor cable to the motor and the power terminals of

the Vacon frequency converter

-check that all start/stop switches connected to the I/O terminals

are in OFF position

-switch the mains ON

-repeat the test A or B of the start-up test #8.

10Connect the motor to the process (if the previous tests were done without the process)

-ensure that the inverter is safe to be powered up

-inform your co-workers about the tests.

-repeat the test A or B of the start-up test #8.
