FLAMEPROOF - SPECIAL CONDITIONS FOR SAFE USE
• Field wiring must be rated 105°C minimum. For ambient temperatures below -10°C, use suitable field wiring.
• Blanking elements from factory have been tested for flameproof “d” and dust “tb” with the enclosure as an assembly and carry no
markings.
• A suitable thermowell made from corrosion-resistant material and engaging 5 threads minimum (with thread sealant) is required for
the local spring loaded temperature sensor to maintain IP66
