6.1 Mounting notes
WARNING!
Before installation, commissioning and operation, ensure that the appropriate instrument has been
selected in terms of measuring range, design and specic measuring conditions.
Non-observance can result in serious injury and/or damage to the equipment.
WARNING!
Danger to life through improper mounting
Improper installation can lead to the loss of the explosion protection and to life-threatening situations.
■
Adhere to the permissible ambient and medium temperatures which are valid for this area on the
basis of the specied temperature classes.
■
Consider possible additional restrictions on the ambient temperature range by the mating connector
used.
■
Guard the pressure transmitter against being touched, or display a warning about risk of burns.
■
Mount the pressure transmitter horizontally in order to ensure unhindered airow around the cooling
element.
■
Protect the pressure transmitter from heat sources (e.g. pipes or tanks).
■
In dust-Ex areas, ensure that the cooling element is not dirty and there is no dust lying on it,
otherwise the cooling action cannot be guaranteed.
■
Observe the specications for the use of the pressure transmitter in combination with aggressive/
corrosive media and for avoiding mechanical hazards.
■
For ignition protection types Ex nA and Ex tc: Install the cable output IP 67 version with protection cap
protected from the inuence of light.
■
For ignition protection type Ex tc: Not suitable for areas where intensive electrostatic charging is likely
to occur.
If the medium temperature to be measured is > 105 °C, then, for the maximum ambient temperature, the tables in
chapter 3.8 “Maximum ambient and medium temperatures for process connections with pressure channel for medium
temperatures > 105 °C” and “Maximum ambient and medium temperatures for ush process connections for medium
temperatures > 105 °C” are valid.
However, the permitted surface temperature values, which apply to this range due to the dened temperature classes,
shall not be exceeded.
