3 Installation
WARNING!
The area where the 9010/9020 SIL control unit is installed must be outside of a hazardous area
Zone 0, 1 or 2 and it must be free of ignitable, explosive or corrosive gases. Detector installation
at the Control unit must be carried out according to relevant local and national regulation
(EN 60079-14).
The installation location for the control unit must be outside of any potentially explosive area and
free of corrosive gases. Detectors for use in the Ex area must have the appropriate Ex approval
and must be installed in accordance with all relevant local and national regulations.
The gas warning system must only be installed by qualified personnel after reading the relevant
documentation (instruction manual for selected detector or transmitter).
The correct assignment of each detector and control unit must be ensured during installation by
referring to the serial numbers indicated on the calibration data sheet provided by MSA.
3.1 Mechanical Installation
Depending on the version the control unit can be installed as a module in 19" rack or as a stand-
alone unit (wall mounted version).
Do not install the control unit in environments that are particularly humid, oxidizing, corrosive,
subject to notable vibrations or in which the temperature limits listed in the Technical Data chapter
are exceeded.
If installation is planned inside cabinets, the standards for maximum permissible temperature
must be observed. Cabinets must provide sufficient heat convection to dissipate heat from various
electronic components on the boards.
There must be sufficient space between the19” racks allowing a good air ventilation. Sufficient
space also needs to be left at the back of the rack to allowing a correct cables connection to the
backplane terminal boards.
The outline dimensions of the available 19" racks can be found in the Appendix. See chapter 12.2.
Backplane terminal unit screws, front panel screws (including blank panels) and rack mounting
screws (M6) must be tighten with a special torque moment in 19" rack.
• 0.3 Nm for backplane terminal screws
• 0.8 Nm for front panel screws
• 10 Nm for rack mounting screws (M6)
The outline dimensions of the available 19" racks can be found in the Appendix. See chapter 12.2.
Wall mounted unit installation instruction:
(1) Mark the holes as shown in chapter 12.3 for the four fixing screws.
(2) Drill four holes (diameter according to used screws).
(3) Remove the lid from the housing.
(4) Fix the control unit to the wall with appropriate screws.
(5) Close the lid with lid screws.
In case the PCB has to be removed (for example if M4 terminal access is needed) release the 3
fixing screws.When re-installing the PCB, tighten the fixing screws using a torque of 1,5 Nm.
Before starting the installation, check that the delivered components are complete and
correct by referring to the shipping documents.
