Installation Procedure
a.
Cut the aperture specified in Fig 3 in the panel
enclosure. Ensure that the edges of the aper-
ture are de-burred.
b.
Inspect the instrument's captive gasket and en-
sure that it is not damaged before inserting the
Set Point Station into the panel enclosure aper-
ture.
c.
If the enclosure panel is less than 1.0mm thick,
or is non-metallic, an optional BEKA stainless
steel support plate should be slid over the rear
of the indicator before the panel clamps are fit-
ted to evenly distribute the clamping force and
prevent the enclosure panel being distorted or
creeping.
d.
Slide a panel clamp into the two grooves at
each corner of the indicator housing with the
M3 stud protruding through the hole at the rear
of the clamp. Fit the stainless steel
spring
washer over the stud and secure with the
stain-
less steel wing nut.
e.
Evenly tighten the four clamps to secure the
instrument.
The
recommended
minimum
tightening torque for each wing nut is 22cNm
(1.95 lbf in).
f.
Connect the panel enclosure wiring to the rear
terminal blocks.
To simplify installation, the
terminals are removable so that wiring can be
completed before the instrument is installed.
Cables should be mechanically secured to en-
sure terminals are not damaged by vibration.
g.
Finally, fit a silicone rubber push-on cap to the
end of each M3 threaded rod.
