Checking the applied voltages
1. Check what voltage is present at the control cable terminals of -A1-X2.
– A voltage of 32 V to 250 V must only be present at the top green terminals and/or at
terminal 37 .
– All other terminals must be supplied with a maximum voltage of 32 V.
2. Compare the line voltage you will apply with the rating plate of the converter.
You will find detailed information in the following table.
3. For cabinet units, identifier 2T..-8....-..., also reconnect the fan transformer -T4 to the
rated mains voltage and check whether the transformer is connected to the correct
voltage.
– Compact units, identifier 2T..-0....-..., supply the fans via the DC link.
– Thus, there is no configuration work for you.

● Set the DIL switches S1 and S2 as required.
More detailed information can be found in the section "DIL switches S1 and S2"
(Page 149).
Performing insulation test
1. Take the necessary safety precautions such as covering neighboring system parts etc.
2. Connect terminals U1, V1, W1, U2, V2, W2.
