Panel-Mounting
The mounting panel must be rigid and may be up to 6.0mm
(0.25 inches) thick. The cut-out required for the instrument is
shown on the right. Instruments may be mounted side-by-side
in a multiple installation for which the cut-out width (for n
instruments) is (48n-4)mm or (1.89n-0.16)inches.

Installing Option Modules
To access modules 1 or A, first detach the PSU and CPU boards from the front moulding by
lifting first the upper, and then lower mounting struts. Gently separate the boards.
a). Plug the required option modules into the correct connectors, as shown below.
b). Locate the tongues on each module into the corresponding slot in the board opposite.
c). Hold the main boards together while relocating them back on the mounting struts.
d). Replace the instrument by aligning the CPU and PSU boards with their guides in the
housing, then slowly push the instrument back into position.
Note: The instrument will automatically detect which option modules have been fitted.
