8. COMMISSIONING
8.1
Safety
Before commissioning, note the following directions and warnings:
1
Internal components and circuit boards of the frequency converter
(except for the galvanically isolated I/O terminals) are live when NXL is
connected to mains potential. Coming into contact with this voltage is
extremely dangerous and may cause death or severe injury.
2
The motor terminals U, V, W and the DC-link/brake resistor terminals –/+
are live when NXL is connected to mains, even if the motor is not
running.
3
The control I/O-terminals are isolated from the mains potential. However,
the relay outputs and other I/O-terminals may have a dangerous control
voltage present even when NXL is disconnected from mains.
4
Do not make any connections with the frequency converter connected to
the mains.
5
After having disconnected the frequency converter 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 NXL connections. Do not even open
the cover before this time has expired.
6
Before connecting the frequency converter to mains make sure that the
NXL front cover is closed.
HOT SURFACE
7
The heat sink of types MF2 and MF3 may be hot when the frequency
converter is in use. Coming into contact with the heat sink may cause
burns.
8.2
Commissioning of the frequency converter
1
Read carefully the safety instructions in Chapter 6 and above and follow them.
2
After the installation, make sure that:
- both the frequency converter and the motor are grounded.
- the mains and motor cables comply with the requirements given in Chapter 6.1.1.
- the control cables are located as far as possible from the power cables (see Chapter 6.1.3,
step 3); the shields of the shielded cables are connected to protective earth . The wires
may not touch the electrical components of the frequency converter.
- For option boards only: make sure that the common ends 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).
4
Check the inside of the frequency converter for condensation.
5
Check that all Start/Stop switches connected to the I/O terminals are in Stop-position.
6
Connect the frequency converter to mains.
7
Set the parameters of group 1 according to the requirements of your application. At least the
following parameters should be set:
- motor nominal voltage
- motor nominal frequency
