Operation
Commissioning Checklist
Before placing the frequency converter into operation, make sure to check the following:
No. Activity Completed Notes
1 Installation and wiring have been carried out in accordance
with the corresponding instructional leaflet (AWA8230-2416)
2 All wiring and line section leftovers, as well as all the tools
used, have been removed from the frequency inverter’s
proximity
3 All terminals in the power section and in the control section
were tightened with the specified torque
4 The lines connected to the output terminals of the frequency
inverter (U/T1, V/T2, W/T3, R+, R–) are not short-circuited and
are not connected to ground (PE)
5 The frequency inverter has been earthed properly (PE)
6 All electrical terminals in the power section (L1, L2/N, L3,
U/T1, V/T2, W/T3, R+, R–, PE) were implemented properly and
were designed in line with the corresponding requirements
7 Each single phase of the supply voltage (L1, L2, L3) is protected
with disconnect device
8 The frequency inverter and the motor are adapted to the input
voltage (see “Nameplate Rating Data”on Page 6, connection
type [star, delta] of the motor tested)
9 The quality and volume of cooling air are in line with the
environmental conditions required for the frequency inverter
and the motor
10 All connected control lines comply with the corresponding stop
conditions (for example, switch in OFF position and setpoint
value = zero)
11 The parameters that were preset at the factory have been
checked with the list of parameters (see “List of Parameters”
on Page 161)
12 The effective direction of a coupled machine will allow the
motor to start
13 All emergency switching off functions and safety functions are
