Transformer Adjustment To Power Supply Voltage - SKF EAZ Mode D'emploi

4.3 Transformer adjustment to power
supply voltage
The cabinets include a transformer for generate
230V for the inside electronics. This must be
adjusted properly to make sure that the output of
this transformer is well within the acceptable range
for the parts connected to it. This operation must be
done by an electrician.
I M P O R TA N T:
Be aware that this adjustment is not changing the
speciications range of the cabinet.
A cabinet meant to work at 400V/50Hz can only be
set at 380 or 420V/50Hz.
A cabinet meant to work at 440-480V/60Hz can
only work at 440, 460 and 480V/60Hz, but not at
400V (for example).
As we can see in the below picture, the transformer
has 6 connection points at the bottom. We must
read the connections table on the transformer:
10 EN
N O T E :
In this case the table is as per below, but this can be
different in the one you have, so always follow the
transformer table and not the table in this manual:
Voltage Independent
connections
380V 0-1
400V 0-5
420V 0-4
440V 0-2
460V 0-5
480V 0-4
In the picture below, for 480V we can see that
connections 0 and 4 are connected.
Also 3 and 5 are connected through a cable which
short circuits them.
