12. Mounting methods
By means of appropriate mounting accessories, the standard
merging unit case can be flush mounted, semi-flush mounted or
wall mounted. The flush mounted and wall mounted merging
unit cases can also be mounted in a tilted position (25°) using
special accessories.
Further, the merging units can be mounted in any standard 19”
instrument cabinet by means of 19” mounting panels available
with cut-outs for one or two merging units. Alternatively, the
merging units can be mounted in 19” instrument cabinets by
means of 4U Combiflex equipment frames.
For routine testing purposes, the merging unit cases can be
equipped with test switches, type RTXP 18, which can be
mounted side by side with the merging unit cases.
