3.2.4 Confirm EZHub Mounting
1. Verify that the enclosure is rated IP55 and provides enough space for the EZHub (per
dimensions shown in section 9.8 or 9.9, depending on mounting style). Check for USB stick
clearance where the EZHub will be installed.
2. Locate the mounting brackets match the type of mounting (panel or wall) planned.

NEMA 4X Enclosure Wall Ensure the enclosure is properly
mounted to wall or Unistrut
stand.
Caution: Direct sunlight will cause heating of the enclosure and may cause overheating
beyond the temperature rating of the EZHub.
3.2.5 Confirm Mounting Location/Type for External Computer or
LumaSMART
i Core (Optional)
In order to configure and operate your SmartDGA system with the software, you will need an
external computer or an
i Core.
Confirm Mounting Location
1. Confirm distance from the external computer or i Core installation location to the EZHub
location to ensure the cable (Ethernet or RS485) is long enough.
Note: If using Ethernet with copper wire, this distance should be less than 100 m (328 ft).
If longer distances are required, a fiber optic connection should be used.
Note: If using the included RS485 to USB converter, the distance between the EZHub and
the external computer cannot be longer than 50 m (164 ft). Use a shielded 18 AWG cable.
2. Ensure the conduit for the connection cable between the EZHub and SmartDGA instrument
is present.
Confirm Mounting Type
External Computer:
If using an external computer, verify that it uses a supported Windows
operating system. Mounting is configuration dependent.
LumaSMART i Core:
1. Verify that the enclosure is rated IP55 and provides enough space for the i Core (per
dimensions shown in section 9.10 or 9.11, depending on mounting style.) Check for USB stick
clearance where the
i Core will be installed.
Caution: The mounting position and location chosen for the i Core should ensure that the
vents on the top of the i Core box will not be blocked during normal operation. Blocked
vents could cause the i Core to overheat.
