Power connection with an auto-transformer
Transformer performance
1.1 x continuous motor power
Secondary voltage
0.9 x motor power
Transformer fuses
Slow acting
Observe the switch-on current!!!
Input fuses
F1, F2, F3
rf. to the table above
Attention:
If the secondary voltages produced by the transformer are inferior to 60%
the voltage watchdog has to be adapted. These modifications may only
be effected in the factory and thus, the voltages have to be indicated on
order.
