EQUITEL – E451 Technical manual
Page 4
The equipment can be PoE powered. This allows the unit to be powered using the same cable employed
for the network connection. With this, we avoid the need of using sockets in those places where the
intercom E451 is installed.
Furthermore, in the case of not having a PoE Ethernet, it is possible to use a +9 to +14 V DC auxiliary
power supply.
Optionally, the unit can be powered at +24 V DC. If so, please contact EQUITEL commercial department or
in

Equipment elements
E451 is housed in a flush or surface mounting enclosure with anti-vandal front and push-button, that confers
a high degree of ruggedness. In Chapter 2 we explain in detail the E451 mechanical mounting for a proper
installation.
We list below the unit most important elements, and in the Figure 3 and Figure 4 it is shown where they are
placed:
