1. Read carefully the safety instructions in Chapter 1 and follow them.
2. After the installation, pay attention:
-
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 and that the
shields of the shielded cables are connected to protective earth
. The wires may not
touch the electrical components of the AC drive.
-
that the common inputs of digital input groups are connected to +24 V or ground of the I/O
terminal or the external supply.
3. Check liquid cooling connections and system operation.
-
open the shut-off valves
-
check the quality and quantity of the cooling liquid (Chapter 5.2)
-
ensure the proper operation of liquid circulation system
4. Perform the cable and motor insulation checks, see Chapter 6.1.10.
5. Check the AC drive for condensation.
6. Check that all Start/Stop switches connected to the I/O terminals are in Stop-position.
7. Connect the AC drive to mains.
8. Set the parameters of group 1 (See VACON
®
All in One Application Manual) according to the
requirements of your application. At least the following parameters should be set:
-
motor nominal voltage
-
motor nominal frequency
-
motor nominal speed
-
motor nominal current
You will find the values needed for the parameters on the motor rating plate.
9. Perform run test without motor
Perform either Test A or Test B:
A Controls from the I/O terminals:
a)
Turn the Start/Stop switch to ON position.
b)
Change the frequency reference (potentiometer).
c)
Check in the Monitoring menu (M1) that the value of Output frequency changes according
to the change of frequency reference.
d)
Turn the Start/Stop switch to OFF position.
B Control from the control keypad:
a)
Change the control from the I/O terminals to the keypad as advised in Chapter 7.3.3.1.
