Transformer protection
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.
Watchdog power connection
BTB inactive
dark LED
>>> missing phase
>>> wrong rotating field
