4 Mounting and Installation
4.1 General
For types with cable gland, use a matching wrench for mounting the cable gland (in the scope of supply) onto the
EE820 enclosure.
When using EE820 with conduit connection use a flat screwdriver to knock open the blind at the top of the
enclosure, carefully. Take good care to avoid damaging the electronics inside the enclosure. The conduit adapter
is not included in the scope of supply. The M16x1.5 opening for the cable gland shall be tightly closed using the
blind plug included in the scope of supply (see also chapter 3.2 Dimensions).
For best measurement results, the EE820
▪
must be installed in an environment where the medium to be measured flows sufficiently around the sensor.
▪
shall not be placed near influencing objects such as heating radiators or fan heaters.
4.2 Electrical Connection
EE820 is available with a cable gland or M12 connection (depending on the order code) and
features screw
terminals for connecting the power supply and the outputs. The cables are fed into the enclosure through the M16
cable gland.
NOTICE
It is important to make sure that the cable glands are closed tightly for the power supply and outputs cable.
This is necessary for assuring the IP rating of the enclosure according to EE820 specification, as well as for
stress relief at the screw terminals on the EE820 board.
WARNING
Incorrect installation, wiring or power supply may cause overheating and therefore personal injuries or
damage to property.
▪
For correct cabling of the device, always observe the presented wiring diagram for the product version
used.
▪
The manufacturer cannot be held responsible for personal injuries or damage to property as a result of
