4.2 Installation Procedure
a. Cut the specified aperture in the panel. To
achieve an IP66 seal between the instrument
enclosure and the instrument panel the
aperture must have the tighter tolerances
specified in Fig 4A and 4B.
b. Slide the gasket over the body of the
indicator before inserting the instrument into
the panel aperture.
c. Firstly ensure that all the panel mounting
clamps are closed by turning the knurled
screws fully anti clockwise until the two pips
in the clamp foot align with holes in the clamp
body.
d. Place a clamp in the recess on each side of
the indicator, pulling gently to slide it onto the
dovetail as shown in Fig 5. Push the knurled
screw slightly forward to engage the thread
and tighten by turning clockwise until it is just
finger tight. When both clamps are fitted
ensure that the gasket behind the front panel
bezel is correctly positioned before fully
tightening the clamps to secure the
instrument. The maximum recommended
clamp tightening torque is 22cNm (1.95 lbf in)
which is approximately equvalent to finger-
tight plus one half turn.
Do not over tighten
.
e. Four panel mounting clamps are required to
achieve an IP66 seal between a BA508E and
BA528E indicator and the instrument panel.
f.
Connect the panel wiring to the rear terminal
block(s) as shown in Figs 4A and 4B. To
simplify installation, the terminals are
removable so that the panel wiring can be
completed before the instrument is installed.
