4. INSTALLATION
4.1 Location
All the models have a robust glass reinforced
modified PPO enclosure with a toughened glass
window. The front of the indicator has IP66
protection and a gasket seals the joint between the
instrument enclosure and the panel. The rear of
the indicator has IP20 protection.
The indicators may be installed in any panel
providing that the operating temperature is
between –40ºC and +70ºC.
Figs 4A and 4B show the overall dimensions of the
96 x 48mm and the 144 x 72mm instruments
together with the recommended panel cut-out
dimensions. To achieve an IP66 seal between the
instrument enclosure and the instrument panel the
smaller tolerance aperture must be used, and the
144 x 72mm models must be secured with four
panel mounting clamps.
Although the indicator front panel provides IP66
protection it should be shielded from direct sunlight
and severe weather conditions.
