/ 98 feet distance);
2 two EMC  lters (code 0907858AXX) to be applied to the ends of the
telephone cable;
3 remote display terminal.
Note: to  ll the empty space left by the display terminal on the

Important: for the RS485 connections in household (IEC EN
55014-1) and residential (IEC EN 61000-6-3) environments, use
shielded cable (with shield connected to PE both on the terminal side
and the controller side) with maximum shielded cable length: speci ed
by the EIA RS485 protocol, equivalent to European stan-dard CCITT V11,
using shielded twisted pair cable, AWG26, 485 input stage impedance
1/8 unit-load (with this con guration, a maximum of 256 devices can be
connected) laid in separate conduits from the power cables.
