5. INSTALLATION
5.1 Location
The BA358E Rate Toyslider has a robust glass
reinforced modified PPO enclosure with a
toughened glass window. The front of the Rate
Totaliser has IP66 protection and a gasket seals
the joint between the instrument enclosure and the
panel. The rear of the instrument has IP20
protection.
The Rate Totaliser will function and is certified
intrinsically safe at ambient temperatures between
–40ºC and +70ºC, but the display only functions at
ambient temperatures between –20ºC and +70ºC.
Fig 4 shows the overall BA358E Rate Totaliser
dimensions 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
should be used, and the Rate Totaliser should be
secured with four panel mounting clamps.
Although the Rate Totaliser front panel provides
IP66 protection it should be shielded from direct
sunlight and severe weather conditions
.

5.2 EMC
The BA358E Rate Totaliser complies with the
requirements of the European EMC Directive
2004/108/EC. For specified immunity all wiring
should be in screened twisted pairs, with the
screens earthed at one point within the safe area.
