The cabinet is designed for either bulkhead mounting or rack mounting.
Once the unit has been mounted, remove the top/bottom gland plate(s) and cut gland holes in the
appropriate position. The cables can then be connected to the in-built MDF mounted in the rear
of the case.
All cables should be securely fastened to prevent damage due to vibrations.
