THERMAL OVERLOAD
Should the unit overheat, the thermal overload will trip, shutting off supply to
the motor/machine. In this event, switch OFF and wait for at least 5 minutes to
allow it to cool before pressing the Reset button (D, Fig.2), and restarting.
You should also investigate the reason for overheating and take the necessary
steps to avoid this re-occuring. If necessary, consult a qualified engineer.
NOTES:
• Please take into account the various losses which are incurred in the
conversion from single to three phase supply. It will be necessary to
select an output from the Converter which is greater than the rated
power of the motor being driven. Ensure also the wiring to the motor is of
sufficient size so as not to incur losses.
• If the machine, which is to be fed from the converter, has a contactor
starter it should be noted that the control circuit should be fed from the
two live phases (pins ‘L1’ and ‘L3 in the socket). Should the contactor
chatter or not operate at all, this indicates that the control circuit is not
fed from lines ‘L1’ and ‘L3’.
• If the control circuit is designed for 230 volts AC, a separate feed for the
control circuit must be provided. Ask a qualified technician if in doubt.
• When using the converter with multispeed machines, care must be take
to allow the machine to slow down before switching from high to low
speeds, If this procedure is not followed, the excess motor, back E.M.F.
could damage both the converter and motor.
