4.4 Switch S5
• SwitchesS5/1,S5/2andS5/3arenotneededon
anyofthefollowerWallboxes.Settheseswitches
to OFF.
• SwitchS5/2isnotrequiredontheleaderWallbox.
SettheswitchtoOFF.

Conguration of blocking function (in leader
Wallbox) via switch S5/3
• TheWallboxhasaninputviawhichitcanbe
blockedbyanexternalswitchingelement
(key-operatedswitchorsimilardevice;see
assemblyinstructions).
• UseswitchS5/3tospecifywhetherthisblocking
istoaffectonlytheleaderWallboxorall
Wallboxes.
S5/3
OFF
OnlytheleaderWallbox
isblocked.
ON
AllWallboxesare
blocked.
4.5 Switch S6
TherstandlastdevicesontheRS485busmustbe
connected with a terminating resistor.
Terminating resistor for last Wallbox
UsemicroswitchS6/2toconnectthebuilt-intermi-
natingresistoronthelastfollowerWallbox.Switches
S6/1,S6/3andS6/4arenotused.Settheseswitches
to OFF position.
S6/2
OFF Bus termination inactive
ON Bus termination active
Local load management
Terminating resistor for leader Wallbox
UsemicroswitchS6/2toconnectthebuilt-intermi-
natingresistorontheleaderWallbox.SwitchesS6/1,
S6/3andS6/4arenotused.Settheseswitchesto
OFF position.
External load management
HEMS terminating resistor
Whenusinganexternalcontrolunit,terminate
thebuslinewitha120Ohmresistor.Observethe
specicationsfromthemanufactureroftheexternal
control system here.
5. Bus protocol
(external load management)
TheModbusRTUprotocolisusedforcommuni-
cationbetweentheexternalcontrolsystemand
theWallboxes.EachWallboxisreadytoreceivea
Modbuscommandonlyaftermorethan10seconds
haveelapsedsincePowerOn.Ifthecorresponding
Wallboxisinstandbymode,itcannotbeaddressed
viaModbus.
