Note:
Most general purpose motors are wound for operation on dual voltage supplies. This is indicated on the
nameplate of the motor. The operational voltage is normally selected when installing the motor by selecting either Star or
Delta connection. Star always gives the higher of the two voltage ratings. Typical ratings are:
Star Delta
/
400V/230 V
690V/400V

Motor protector
Connect a PTC thermistor motor protector to terminals 6 and 7: use a cable with a minimum cross-section of 1 mm²;
alternatively, a Klixon thermostat can be connected (see the general connection diagram). The PTC thermistor must
be selected so that at activation temperature the resistance is >2600 Ω.
