Install the instrument so that the detachable power cord is readily identifiable and is easily
reached by the operator. The detachable power cord is the instrument disconnecting device. It
disconnects the mains circuits from the mains supply before other parts of the instrument. The
standby switch is only a standby switch and is not a LINE switch. Alternatively, an externally
installed switch or circuit breaker (which is readily identifiable and is easily reached by the
operator) may be used as a disconnecting device.
