CAUTION
Drive-Source Cutoff Relay Error (Detection of Fused Relay:
E6D)
As a condition limited to X-SEL-P type controllers of standard single-phase specification, a “drive-source
cutoff relay error (E6D)” may generate if the power is turned off and then turned on again (reconnected)
too quickly. This error indicates that the internal relay has fused, and its occurrence has to do with the
specific circuit configuration of the above controller type.
Although the specific wait time varies depending on the input voltage and number of external regenerative
resistors connected, as a general guide wait for at least 40 seconds before reconnecting the power.
