Location:
Install the instrument on a stable position and assure that mechanic vibration, heat source influence
and draft are reduced to a minimum. The instruments are insensitive to mounting position.
2.5 Leak check
Check the system for leaks before applying (fluid) pressure. Especially if toxic, explosive or other
dangerous fluids are used!
2.6 Electrical connection
Electrical connections must be made with standard cables or
according to the applicable hook-up diagrams. These documents

Please note that LIQUI-FLOW mini instruments are dustproof according to IP40, implying that the
electronics housings and electrical connections do not offer any protection against moist
environments.
The instruments contain electronic components that are susceptible to damage by electro static
discharge. Proper handling procedures must be taken during installation, removing and connecting the
electronics.
The instruments described in this manual carry the CE-mark and are complient with the EMC
requirements. However compliance with the EMC requirements is not possible without the
use of proper cables and connector/gland assemblies. Bronkhorst High-Tech B.V. recommends the use
of their standard cables. These cables have the right connectors and if loose ends are used, these will be
marked to prevent wrong connection. When using other cables, cable wire diameters should be
sufficient to carry the supply current and voltage losses must be kept as low as possible. When in doubt:
contact your distributor.
When connecting the system to other devices (e.g. to PLC), be sure that the integrity of the shielding is
not affected. Do not use unshielded wire terminals.
