mounting
The relay case is basically designed for flush-
mounting. The mounting depth can be reduced
by the use of a raising frame: type SPA-ZX 111
reduces the depth behind the mounting panel
by 40 mm, type SPA-ZX 112 reduces the depth
by 80 mm and type SPA-ZX 113 reduces the
depth by 120 mm. The relay can also be mounted
in a case for surface mounting, type designation
SPA-ZX 115.
