Specific Conditions of Safe Use (X):
1. Flameproof joints are not intended for repair.
2. Non-standard paint options may cause risk from electrostatic
discharge. Avoid installations that cause electrostatic build-up
on painted surfaces, and only clean the painted surfaces with a
damp cloth. If paint is ordered through a special option code,
contact the manufacturer for more information.

Additional Specific Conditions of Use (X) when "XA" designation is

ordered:

1. Guard DIN Style sensors against impacts greater than 4J.

2. The spring loaded adapter style sensors and DIN style sensors
must be installed in a thermowell to maintain Ex tb protection.
