RICAL CONNECTION POWER CIRCUIT The IMS is designed to operate with or without a line contactor In many regions there is a statutory requirement that a line contactor be employed with electronic motor control equipment From a safety point of view this is the preferable option however is not necessary for starter operation The IMS can directly control a line contactor via the Main Contactor Control output 13 14 As an alternative to a line contactor either a circuit breaker with a no volt release coil operated by the IMS trip output 41 42 44 or a motor operated circuit breaker can be considered If a motor operated circuit breaker is used as a line contactor the potential delay between the breaker being told to close and phase power being applied to the IMS could cause the IMS to trip on installation faults This can be avoided by closing the motorised breaker directly and using the breakers auxiliary contacts to control the IMS Fast acting semiconductor fuses can be used with the IMS to reduce the potential of damage to the SCRs from transient overload currents Refer to your starter supplier for semiconductor fuse selection advice If the IMS is to be mounted in a non ventilated enclosure a bridging contactor should be employed to eliminate heat build up in the enclosure Bridging contactor can be AC1 rated as it only carries the running current of the motor The bridging contactor should be controlled by the IMS Run output
