DANGER!
Danger to life from explosion
Through working in flammable atmospheres, there is a risk of explosion which
can cause death.
▶
Only carry out set-up work in non-hazardous environments!
▶
Do not open the instrument while under voltage.
DANGER!
Danger to life from explosion
By using a measuring insert without a suitable connection head (case), an
explosion risk occurs which can cause fatalities.
▶
Only use the measuring insert in the connection head designed for it.
DANGER!
Danger to life due to loss of explosion protection
If the corresponding tightening torques are not observed, this can lead to a
loss of the explosion protection.
▶
Ensure the tightening torques in accordance with chapter 3.2.
WARNING!
Damage to the measuring instrument by operation outside the upper or
lower limits of the operating temperature
Failure to observe the permissible operating temperature, also taking into
account convection and radiation, can even cause damage to the thermometer
during mounting.
▶
The upper and lower limits of the specified operating temperature range
must not be exceeded.
WARNING!
Potential electrostatic charging hazard
There is a risk of electrostatic discharges for group IIIC EPL Db.
▶
For application in areas requiring EPL Db equipment and in areas with
high or repeated charging processes, special protective measures must be
taken.
Observe the special conditions (see chapter 4 “Special conditions for use (X conditions)”).
