Commissioning of the AC drive

1
Read carefully the safety instructions in Chapter 1 and above and follow them.
2 After the installation, pay attention to:
- that both the AC drive and the motor are grounded.
- that the mains and motor cables comply with the requirements given in Chapter 6.1.1.
- that the control cables are located as far as possible from the power cables (see Chapter
6.1.5, step 3) , the shields of the shielded cables are connected to protective earth
wires may not touch the electrical components of the AC drive.
- that the common inputs of digital input groups are connected to +24V or ground of the I/O
terminal or the external supply.
3 Check the quality and quantity of cooling air (chapter 5.2 and Table 5-11).
4
Check the inside of the AC drive for condensation.
5
Check that all Start/Stop switches connected to the I/O terminals are in Stop-position.
6
Connect the AC drive to mains.

Internal components and circuit boards of the AC drive (except for the
galvanically isolated I/O terminals) are live when Vacon NX_ is connected
to mains potential. Coming into contact with this voltage is extremely
dangerous and may cause death or severe injury.
The motor terminals U, V, W and the DC-link/brake resistor terminals –/+
are live when Vacon NX_ is connected to mains, even if the motor is not
running.
The control I/O-terminals are isolated from the mains potential. How-
ever, the relay outputs and other I/O-terminals may have a dangerous
control voltage present even when Vacon NX_ is disconnected from
mains.
Do not make any connections with the AC drive connected to the mains.
After having disconnected the AC drive from the mains, wait until the fan
stops and the indicators on the keypad go out (if no keypad is attached
see the indicator through the keypad base). Wait 5 more minutes before
doing any work on Vacon NX_ connections. Do not even open the cover
before this time has expired.
Before connecting the AC drive to mains make sure that the Vacon NX_
front cover is closed.
When running, the side of converter FR8 is burning hot. Do not touch with
hands!
When running, the back of AC drive FR6 is burning hot. Therefore it
MUST NOT be mounted onto a surface which is not fireproof.
