The link module is first attached to the device to be connected, then the resulting unit is
plugged on to the motor starter protector. This ensures that the requisite electrical and
mechanical connections are established in the main circuit. Overload relays and current
monitoring relays can easily be attached to contactors and solid-state switching devices in a
similar way, without the need for another link module:
