Mounting
For the
mini CORI-FLOW ML120
proper stable mounting is strongly advised on
a rigid, solid base for optimal accuracy. For optimal isolation from vibrations in
the area, rubber suspension pads can be used.
The picture to the right shows an example of a
mini CORI-FLOW ML120
with a
mass block, one of the options Bronkhorst can provide for isolation from
vibrations in the environment where the instrument is used.
Please see
Quick Installation Guide, document no 9.17.093
for more detailed information about mounting.

Leak check
Bronkhorst®
mini CORI-FLOW
meters/controllers are fitted with compression or face-seal-fittings.
For leak tight installation of compression type fittings make sure that the tube is inserted to the shoulder in the fitting
body and that no dirt or dust is present on tube, ferrules or fittings. Tighten the nut finger-tight; while holding the
instrument and then tighten the nut 1 turn.
If applicable follow the guidelines of the supplier of the fittings. Special types of fittings are available on request.
Check the system for leaks before applying pressure, especially if toxic, explosive or other dangerous fluids are used.
2.6
Electrical connection
Electrical connection must be made with standard cables or according to the applicable hook-up diagrams. The factory
installed 9-pin D-sub settings are indicated on the instrument label. Make sure that the power supply is suitable for the
power ratings as indicated on the instrument label and that double or reinforced insulation is used for the power supply.
Bronkhorst recommends using their standard cables. These cables have the right connectors and if loose ends are used,
these are marked to prevent wrong connection.
Hook-up diagrams for MLxxx series instruments can be found at

mini CORI-FLOW ML120
series instruments are powered with +15…+24 Vdc. See the hook-up and cabling examples in
section
Do not power the instrument simultaneously from two different power sources (e.g. fieldbus connection and Plug-in Power
Supply). Doing so will damage the printed circuit board irreparably.
The device contains electronic components that are susceptible to damage by
electrostatic discharge
. Proper handling
procedures must be taken during installation, removing and connecting the electronics.
The device described in this manual carries the CE-mark and is
compliant with the concerning EMC requirements
.
However, compliance with the EMC requirements is not possible without the use of proper cables and connector/gland
assemblies Bronkhorst recommends the use of their standard cables. These cables have the right connectors and if loose
ends are used, these are marked to prevent wrong connection. When using other cables, cable wire diameters should be
sufficient to carry the supply current, and voltage loss must be kept as low as possible. When in doubt, contact your
distributor.
When connecting the product to other devices (for instance a PLC), be sure that the integrity of the shielding is not affected.
Do not use unshielded wire terminals
