3. INSTALLATION
3.1 Location
The BA577E has a robust glass reinforced Noryl
enclosure with a toughened glass window. The front
has IP66 ingress protection and a gasket seals the
joint between the instrument enclosure and the
panel, the rear of the instrument has IP20 ingress
protection.
The BA577E may be installed in any panel providing
that the operating temperature is between -40°C and
+70°C.
At temperatures below -20°C the display
will become increasingly slow with reduced contrast
but the instrument will continue to function normally.
Fig 4 shows the overall dimensions of the instrument
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.
Although the front of the BA577E has IP66
protection it should be shielded from continuous
direct sunlight and severe weather conditions.
4.2 EMC
The BA577E complies with the requirements of the
European EMC Directive 2014/30/EU. For specified
immunity all wiring should be in screened twisted
pairs, with the screens earthed at one point.
