Mount and Wire the CAEN-BLOCK-CENCN-2-POE
Mount the CAEN-BLOCK-CENCN-2-POE in accordance with all national and local codes.
Use the two 8B x 1/4” screws, supplied, to attach the CAEN-BLOCK-CENCN-2-POE to an
enclosure. The first illustration below shows the CAEN-BLOCK-CENCN-2-POE mounted in
a single-wide enclosure; the second illustration shows the double-wide enclosure.
NOTE
: The equipment is only to be connected to PoE networks without routing to
outside plants.
* The 24 Vdc power supply must be capable of delivering 75 W to the load when plugged in alone or
while in conjunction with the PoE or PoE+.
** If another power supply is used, the power supply must be UL or cUL Listed or have equivalent NRTL
certification with the minimum power ratings shown, have an LPS output, and be rated for use in an
ambient temperature of 40 °C.
Replace the Divider
NOTE
: Class 1 and Class 2 wiring must be separated. Ensure that the correct divider is
used.
Replace the divider.
1. Remove the two screws that secure the divider in the enclosure. Discard the screws
and the divider.
2. Using the supplied screws and nuts, secure the new divider to the side of the
enclosure.

NOTE
: When installing the CAEN-BLOCK-CENCN-2-POE in a single-wide enclosure,
use the gray module interconnect cable to make the connection between the module
and the RIGHT port on the CAEN-BLOCK-CENCN-2-POE.
NOTE
: When installing the CAEN-BLOCK-CENCN-2-POE in a double-wide enclosure,
use the red module interconnect cable to make the connection between the right
module and the RIGHT port on the CAEN-BLOCK-CENCN-2-POE. Use the gray module
interconnect cable to make the connection between the left module and the LEFT port
on the CAEN-BLOCK-CENCN-2-POE.
