8 Changing the sensor

Danger of explosion! Do not change the sensor in explosion-hazard areas.
Substitution of components may impair intrinsic safety!
To prevent ignition of flammable or combustible atmospheres, and to avoid
compromising intrinsic safety of the equipment, read, understand, and
adhere to the maintenance procedures below.
Take care when changing the sensors not to damage or short out compo-
nents, and do not use sharp tools to remove the sensors.
Damage to components!
The instrument contains components that are sensitive to electrical charges.
To prevent damage to the instrument, make sure that the person working on
the instrument is earthed prior to opening it for sensor replacement. Earth
contact can, for example, be ensured by an ESD (electrostatic discharge)
workplace.
