4. WIRING INSTRUCTIONS
Ethernet RJ45 wire
Ipercom system is developed for to work with the EIA/TIA 568B standard.
• Plug the cable into one of the RJ45 connectors with the Urmet logo.
• Insert the wire in its guide, according to the provided colour code (Standard T568B).

• Make sure that the grey sheath stays inside the plug. This type of connection will NOT guarantee double
insulation.
• Connect one end of the Ethernet cable to the POE switch of the system and the other end to the LAN
connector of the device.
When using the local power supply, first connect the LAN cable to a
non-POE
port on the switch and then
connect it to the local power supply.
4.1 POWER SUPPLY
The 1761/31 or /33 IP video door phone can be supplied power in two different ways:
—
POE
—
48 V
local power supply
When the power supply is used, POE is not available because the video door phone is powered only by the
local power supply. In this case, RJ45 can be connected to the NO POE port of the switch.

or larger must comply with IEC 60332-1-2; wires with cross
section area smaller than 0.5 mm
2
must comply with IEC 60332-2-2.
(*) To ensure longest-range video door phone operation, the cable must be a class 5e device and the
twisted pairs’ cross section must be AWG24.
The maximum resistance of the individual wires must not exceed 10ohm/100m.
The cable must be up to the following standards:
- EIA/TIA 568-B.2 or EIA/TIA 568-C.2
- EN50288 3-1
- IEC 61156-5
The connection between the IP video door phone and POE switch must be ensured by a single cable
without any extra patch cords.
