19. Mounting methods
By means of appropriate mounting acces-
sories the standard IED case for the 615
series IEDs can be flush mounted, semi-flush
mounted or wall mounted. The flush mount-
ed and wall mounted IED cases can also be
mounted in a tilted position (25°) using spe-
cial 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 IEDs
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,
type RTXP 18, which can be mounted side by
side with the IED cases.

Mounting methods:

• Flush mounting
• Semi-flush mounting
• Semi-flush mounting in a 25° tilt
• Rack mounting
• Wall mounting
• Mounting to a 19" equipment frame
• Mounting with a RTXP 18 test switch
to a 19" rack

20. IED case and IED
plug-in unit
For safety reasons, the IED cases for current
measuring IEDs are provided with automati-
cally operating contacts for short-circuiting
the CT secondary circuits when a IED unit
is withdrawn from its case. The IED case is
further provided with a mechanical coding
system preventing current measuring IED
units from being inserted into a IED case for
a voltage measuring IED unit and vice versa,
i.e. the IED cases are assigned to a certain
type of IED plug-in unit.
