Mains Distro- High Voltage

Distro Mk1

The Mains Distro for territories with a high mains voltage (above 200V AC) is housed in a 6U tall 19"rack–mount enclosure and
features a 32A three phase Ceeform inlet. There are three mains LEDS which show the presence of mains on the three phases.
This is fed to two rows of six double pole 16A combined residual current breakers the outlet of which feeds two Tourmate 19-
pin female outlets, one from the top row of breakers and the second from the bottom row each delivering 6 channels of mains.
The three phases are split across the outlets with Phase 1 fed to breakers 1 and 2, phase 2 to breakers 3 and 4 and phase 3 to
breakers 5 and 6. The top row are labelled circuits 1 to 6 and the bottom row 7 to 12.
The Tourmate wiring configuration is the same standard as used for Socapex style connectors in the lighting industry and is as
follows;-
Circuit Number
1 & 7
2 & 8
3 & 9
4 & 10
5 & 11
6 & 12
The Distro also has four 13A outlets on the rear to power the control electronics within the Master and Slave racks. These are
fed individually from circuits 3, 6, 9 and 12.

Distro Mk2

The latest version of the Distro has a few enhancements following feedback from MLA partners. The 32A Ceeform inlet has been
rotated through 90⁰ anticlockwise as it had been found that the cover on the cable mount mating connector would obstruct the
connector panel above in racks with two distros. The cover now harmlessly sticks out to the left of the panel when mated.
There is also an additional 16A breaker on the top row which is a dedicated independent feed for the 13A outlets on the rear of
the distro. This allows mains isolation of all cabinets without disturbing the mains feed to the Merlin and network products.
