WARNING
The equipment has a non-conducting coating and may generate
an ignition-capable level of electrostatic charges under certain
extreme conditions. The user should ensure that the equipment
is not installed in a location where it may be subjected to external
conditions (such as high pressure steam) which might cause a
build up of electrostatic charges on non-conducting surfaces.
Additionally, cleaning of the equipment should be done with a
damp cloth.
m
WARNING
Any cable glands used with this product shall be provided with
protection d for hazardous location category IIC with certificate,
according to TP TC 012/2011.
SPECIAL CONDITIONS FOR SAFE USE
Honeywell explosion-proof switches are designed specifically
Sensing and Control
II2GD
for use in hazardous location applications. The BX2 enclosure
is sealed for protection against corrosion, water, dust and oil
as defined in NEMA 1, 3, 4, 4X, 6, 13 and IP67 (per IEC60529).
The temperature rating for these products depends upon the
seal material used. Products using a fluorosilicone seal have a
rating of -40 °C to 70 °C [-40 °F to 158 °F]. Products using a
fluorocarbon seal have a rating of -12 °C [10 °F] to 70 °C [158
°F]. MICRO SWITCH BX switches are rated according to the
electrical ratings detailed in Table 1.
