INSTALLATION
NOTE: Warranty is void if the MetStream case is opened.
Installation Guidelines
5.1
The MetStream 100 is designed for indoor use.
For outdoor use a suitable sealed enclosure that meets the required environmental
conditions can be used.
o
Gill instruments can supply an outdoor IP65 enclosure; refer to the
technical specification in the front of this manual to ensure it meets the
required conditions of use.
Ensure the product is correctly earthed in accordance with this manual.
Use cables recommended by Gill, keeping the length below the maximum allowed.
Where the cables are cut and re-connected (junction boxes, plugs and sockets) the
cable screen integrity where applicable must be maintained, to prevent the EMC
performance being compromised.
Earth loops should not be created – earth the system in accordance with the
installation guidelines.
Ensure the power supply operates to the MetStream 100 specification at all times.
Bench system test
Note: Prior to physically mounting the MetStream 100 in its final location, we strongly
recommend that a bench system test be carried out to confirm the system is configured
correctly, is fully functional and electrically compatible with the selected host system and
cabling (preferably utilising the final cable length). The required data format, units and
other options should also all be configured at this stage.
Ensure that any unit connected to the MetStream data input has been configured first for
the required Communication protocol and baud rate.
