WARNING
The actuator's surface temperature is dependent upon
process operating conditions. Personal injury or property
damage, caused by re or explosion, can result if the actuator's
surface temperature exceeds the acceptable temperature
for the hazardous area classication. To avoid an increase of
instrumentation and/or accessory surface temperature due
to process operating conditions, ensure adequate ventilation,
shielding or insulation of these actuator components installed in
a potentially hazardous or explosive atmosphere.
Table 3. Temperature Range for (Potential)
Explosive Areas
Notes:
1. The actual maximum surface temperature depends not on the
equipment itself, but mainly on operating conditions e.g., the
temperature of the supply media.
2. The specied values are valid with condition: Maximum cycle
frequency of the actuator is 1 Hz at a maximum of 50 cycles per
hour and at maximum load.
