5.5 Electrical Installation
5.5.1 Power Supply
For the power supply, isolated power is required. The manufacturer supplies an appropriate power supply as
accessory, see section 12.1.6 Power Supply DIN Rail (E-SYSPS), page 90. Beware of use of other power supplies,
which may not provide the necessary isolation and could cause instrument malfunction or damage!
5.5.2 Ethernet Connector
The Ethernet connector is a M12 4-socket connector type, D-coded, and a screw retention feature.

For available Ethernet cables, see section 12.1.3 Ethernet PoE Cable (E-ETHxTCBxx), page 87.
5.5.3 Power over Ethernet (PoE)
The sensor is supplied with power via the PoE standard (Power over Ethernet). PoE allows a single cable to
provide both data connection and electric power to the sensor. The following figure shows exemplarily the
connection to a PC.
