Safety notes for installation in hazardous areas:
1) Install according to the manufacturer's instructions and other valid standards and guidelines.
2) The Micropilot is to be connected to the local equipotential bonding system.
The input circuit is galvanically connected to the housing.
3) The dependency of the permissible ambient temperature of the electronic housing upon the application and temperature
class is given in Tables 1 and 2.
4) If the housing is realigned, check that the locking screw is screwed tight again, see operating manual.
5) A label must be attached to the terminal compartment:
