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
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

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.

5.5.4 12-pin Connector

The 12-pin connector comes in M16 metric thread and supports the RS485 interface, trigger input, relay contact,
current input, current output and the power supply line. Refer to the following figures below for the wiring layout.
