Instruments may be mounted side-by-side in a multiple installation, but instrument to panel
moisture and dust sealing will be compromised. Allow a 20mm gap above, below and behind
the instrument for ventilation. The cut-out width (for n instruments) is:
(96n - 4) mm or (3.78n - 0.16) inches
If panel sealing must be maintained, mount each instrument into an individual cut-out with
10mm or more clearance between the edges of the holes.
Note: The mounting clamp tongues may engage the ratchets either on the sides
or the top/bottom faces of the Instrument housing. When installing several
Instruments side-by-side in one cut-out, use the ratchets on the top/bottom faces.
CAUTION: Ensure the inside of the panel remains within the instrument
operating temperature and that there is adequate airflow to prevent
overheating.

1. Insert instrument into the
panel cut-out.
2. Hold front bezel firmly
(without pressing on the
display area), and re-fit
mounting clamp. Push the
clamp forward, using a tool if
necessary, until gasket
compresses and instrument
is held firmly in position.
Figure 2. Panel-Mounting the instrument
CAUTION: Do not remove the panel gasket, as this may result in inadequate
clamping and sealing of the instrument to the panel.
Once the instrument is installed in its mounting panel, it may be subsequently removed from
its housing if necessary, as described in the Fitting and Removing Plug-in Modules section.
Cleaning
Clean the front panel by washing with warm soapy water and dry immediately. If the USB
option is fitted, close the USB port cover before cleaning.
Note: For an effective IP66 seal against dust and moisture, ensure gasket is well
compressed against the panel, with the 4 tongues located in the same ratchet
slot.
