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.

Configuration 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.

Switch S6

The first 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.

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.

120 Ohm
HEMS terminating resistor
When using an external control unit, terminate
the bus line with a 120 Ohm resistor. Observe the
specifications 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.
