mounting
The basic model of the regulator case is designed
for flush-mounting but, when required, the
mounting depth of the case can be reduced by
means of raising frames.
Three types of raising frames are available: type
SPA-ZX 301 reduces the depth by 40 mm, type
SPA-ZX 302 by 80 mm and type SPA-ZX 303
by 120 mm.
