If the temperature of the brake resistor gets too high and the thermal switch drops

out, the frequency converter will stop braking. The motor will start coasting.

A KLIXON switch must be installed that is `normally closed'. If this function is not

used, 106 and 104 must be short-circuited together.

Terminal

No.

Function

88, 89 Loadsharing

The connection cable must be screened and the max. length from the frequency converter to the

DC bar is 25 metres (82 feet).

Load sharing enables linking of the DC intermediate circuits of several frequency converters.

Please note that voltages up to 1099 V DC may occur on the terminals.

Load sharing calls for extra equipment. For further information please consult Load-

sharing Instructions MI.50.NX.XX.
