There is a post from a few years ago about fuse blowing problems with the then new Explorer. I reported a consistent problem if a Z1000 was placed between the transformer and the Explorer. When a derailment occurred, the fuse would blow. The advice given by MTH was the Explorer should be connected directly to the Explorer. They thought it might be due to the wave form change caused by the Z1000.
I am not sure why you would want to feed the output of the Z1000 into the Explorer if you were running conventionally. Every time you turned the throttle off the Explorer would probably have to reboot. The reason I had experimented with the Z1000 between the brick and the Explorer was I wanted to reduce the track voltage down so I could run Legacy engines. If you want to run both conventional and DCS engines on the same loop of track (but not at the same time, of course) I would connect both the Z1000 and the Explorer each directly to the track and then connect the brick to whichever one was appropriate for the engine I was running.
