16 Assembly and disassembly
16.1 General notes
Assembly and disassembly work on and with the monitoring unit may only be performed by an
authorised specialist familiar with the safety regulations governing handling electrical
components! When using EX-certified monitoring units in potentially explosive atmospheres, the
professional must also be familiar with the relevant safety regulations!
Before assembly and disassembly disconnect the monitoring unit from the power
supply! Separate plug connections must always be de-energized! If EX-certified
monitoring is operated in a potentially explosive atmosphere, there is otherwise an
explosion hazard, due to spark formation!
The monitoring unit housing must be earthed via the fastening - through the
machine earth of the mounting surface or through a separate protective conductor (PE)!
