Measures
In the interest of safety, observe the following precautionary measures:
WARNING
Type of protection "Flameproof enclosure d"
Devices with "pressure-resistant encapsulation" protection may only be opened when the
power has been disconnected.
Type of protection "Intrinsic safety i"
"Intrinsically-safe" devices lose their certification as soon as they are operated on circuits
which do not correspond with the test certification valid in your country.
Type of protection "Increased safety e"
Devices with the type of protection "Increased safety" must not produce sparks or electric
arcs during operation under normal conditions. Electrical equipment and parts must not
exceed a rated voltage of 11 kV.
Type of protection "Mold encapsulation m"
Devices with the type of protection "Mold encapsulation" are potted in casting compound.
Type of protection "By means of enclosure t"
Devices with the type of protection "By means of enclosure" prevent the penetration of dust
or reduce it to a harmless level. Explosive equipment can be installed. The temperature on
the housing must not ignite the surrounding atmosphere.
WARNING
Use in environments with aggressive and dangerous media
The device can be operated both at high pressure and with aggressive and hazardous media.
Therefore, improper use of this device may lead to serious injury and or considerable damage
to property. Above all, it must be noted when the device was in use and is to be exchanged.
CAUTION
Electrostatic sensitive devices
This device contains electrostatic sensitive devices. ESD devices can be destroyed by
voltages well below the threshold of human perception. These static voltages develop when
you touch a component or electrical connection of a device without having discharged the
static charges present on your body. The damage to a module as a result of overvoltage
cannot usually be detected immediately. It may only become apparent after a long period of
operation.
