We have to use the duracom dc dc isolators for them but no issues once
we do it.
Basically same thing using meanwell product.

Have you tried isolating the PTP600 with a DC/DC converter
(Meanwell RSD, etc) in between the rectifier and PIDU?

ill check, but we did a bench test and it did not replicate

If you put the PIDU and PTP600 on a cardboard box or other
insulating surface, can you see –48 VDC on their cases or
chassis?

i think so, afaik is floating ground

So we are moving a site form AC to DC -48
this is the setup:
Emerson Rectifier feeding:
Telco System MPLS router
Planet Fiber SW
2 Netonix DC Switches
2 SAF POE Injectors
2 PTP600 PIDUs
AFAIK all the mentioned gear above are floating ground
We have this gear connected to the Netonix:
Airfiber24, Epmp, PMP450
all wireless gear is using shielded cable that is
terminated in a WBMGF SS on the rack
So this is the issue, we migrated everything to DC,
when we connect the PTP600 PIDU to the rectifier, the
fuse on the emerson output feeding the Netonix
blows..not instantly.. it takes some 30-45 secs..
im scratching my head on this one... any ideas?
