Wiring the Power over Ethernet (PoE) power

The transmitter supports both IEEE 802.3af and IEEE 802.3 standards for PoE. Use this
procedure if you are using PoE from Power Sourcing Equipment (PSE) through the
Ethernet cable.
Prerequisites
The PSE connecting to the 1600 transmitter must be labeled as compliant with either the
IEEE 802.3af standard or the IEEE 802.3at standard. Check the specific manufacturer's
specifications of any device to make sure it references IEEE 802.3 or it may not work with
the 1600 transmitter.
NOTICE
If the installation requires NAMUR NE-21 certification on the customer side, you should
use shielded Cat5e or shielded high-rated cables.
Note
The1600 transmitter belongs to PD (Power Device) Classification 3 in the IEEE 802.3af and
802.3at standards. If the installation uses Cat5e or Cat6 Ethernet cables, the transmitter
supports both Mode A and Mode B power delivery. If the installation uses D code M12
cables, the transmitter only supports Mode A power delivery.
If the transmitter is in a hazardous area, do not remove the housing cover while the
transmitter is powered up. Failure to follow these instructions can cause an explosion
resulting in injury or death.
NOTICE
If both PoE and an external supply power is wired to VDC+, VDC-, the transmitter
automatically switches the power to the DC power input.
Procedure
1. Remove the housing cover and the display, where applicable.
2. Connect the PoE on Channel A (refer to
