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: specifi 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 confi guration, a maximum of 256 devices can be connected) laid in
separate conduits from the power cables
