4.1 Checklist for commissioning
Before placing the frequency converter into operation, use the checklist
below to make sure that all the following requirements are met:
No. Activity Notes
1 Mounting and wiring have been carried out in accordance with the
corresponding instructional leaflet (￫ IL04020015Z, IL04020011Z,
IL04020012Z, IL04020010Z).
2 All wiring and line section leftovers, as well as all the tools used, have been
removed from the variable frequency drive’s proximity.
3 All connection terminals in the power section and in the control section were
tightened with the specified torque.
4 The lines connected to the output terminals (U, V, W, DC+, DC-, BR) of the
variable frequency drive are not short-circuited and are not connected to
ground (PE).
5 The variable frequency drive has been earthed properly (PE).
6 All electrical connections in the power section (L1/L, L2/N, L3, U, V, W, DC+,
DC-, BR, PE) have been connected properly while taking into account the
degree of protection and have been dimensioned in line with the
corresponding requirements.
The device fan in frame size FS8 requires a connection with the correct
phase sequence (L1–L2–L3). – check the airflow’s direction.
7 Each single phase of the supply voltage (L or L1, L2, L3) is protected with a
fuse.
8 The variable frequency drive and the motor are adapted to the mains voltage.
(￫ Section 1.4.1, „Rating data on the nameplate“, page14, 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 variable frequency drive and the motor.
10 All connected control cables comply with the corresponding stop conditions
(e.g., 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.
12 The effective direction of a coupled machine will allow the motor to start.
13 All emergency switching off functions and safety functions (￫ Section
2.10, „STO function“, page59) are in an appropriate condition.
