20. Mounting methods

By means of appropriate mounting
accessories the standard IED case for the 615
series IED can be flush mounted, semi-flush
mounted or wall mounted. The flush
mounted and wall mounted IED cases can
also be mounted in a tilted position (25°)
using special accessories.
Further, the IEDs can be mounted in any
standard 19" instrument cabinet by means of
19" mounting panels available with cut-outs
for one or two IEDs. Alternatively, the IED
can be mounted in 19" instrument cabinets
by means of 4U Combiflex equipment frames.
For the routine testing purposes, the IED
cases can be equipped with test switches,
