3.2 Installation requirements
3.2.1 Inlet, outlet and recommended mounting area
To perform an accurate flow measurement preferably mount the sensor rail at least 10 DN
downstream of a flow disturbance like elbow, valve, header or pump. Please follow the
installation recommendations in the next installation position examples.
CAUTION!
•
In order to comply with the EMC directive 2004/108/EC, I/O cables that provide a galvanic
connection to the UFC 400 P should have a maximum total length of 3 meter.
•
When not used, put the connector covers of the connectors on the bottom side of the
converter in place. This to prevent improper functioning caused by dust/dirt.
•
When the sensor cables are connected while the converter is positioned on a flat surface,
turn the handle fully backwards (towards the housing) in order to prevent excess stress on
the sensor cables.
•
With an empty main battery, the backup battery of the real time clock may run empty when
this is the case for a period longer than one year.
•
The protection degree of the battery charger / mains adapter is IP 40 / NEMA 1. It should be
protected against moisture entering.
• To prevent damage due to vibrations, do not firmly attach the converter to or place it on top of
a vibrating object.
