4.1 Checklist for commissioning
Before placing the variable frequency drive into operation, use the checklist
below to make sure that all the following requirements are met:
No.
Activity Note
1
Mounting and wiring have been carried out in accordance with the
corresponding instructional lea
fl
et (
￫
IL04020010Z, IL040049ZU,
IL04020012Z, IL04020011Z, IL04020015Z).
2
Potential wiring and line section leftovers, as well as all the tools used, have
been removed from the variable frequency drive's proximity.
3
All terminals in the power section and in the control section have been
tightened with the specified torque.
4
The lines connected to the output terminals of the variable frequency drive
(U/T1, V/T2, W/T3, DC+, DC-, BR) are
not
short-circuited and
not connected
to ground (PE).
5
The variable frequency drive has been grounded 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
protection level 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 direction of the airflow.
7
Each individual phase of the supply voltage (L or L1, L2, L3) is protected with
a fuse.
8
The variable frequency drive and the motor are matched to the mains
voltage. (
section 1.4.1, “Rated operational data on the rating plate”,
page 15, 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”, page 68) are in an appropriate condition.
