CAUTION
RISK OF DAMAGE TO DEVICES
Do not connect the SmartWire-DT line to the easy communication
module
or disconnect it without first de-energizing the system.

munication wires, this ribbon cable carries the power supply for the SWD modules,
the switchgear, as well as control wires for assigning addresses.

Tab. 131: Pin assignment for SmartWire-DT ribbon cable interface (pin header, 8-pin)
8-pin SWD4-8MF2 blade terminals need to be connected at the beginning and end of
the SWD ribbon cable. Look for the directional arrow on the ribbon cable in order to
identify where the SmartWire-DT ribbon cable starts and connect the corresponding
connector to the EASY-COM-SWD-… module's SWD OUT connector.
Only use the following ribbon cables to connect the SmartWire-DT line to the SWD
OUT connector:
l
SWD4-100LF8-24 with the relevant blade terminals SWD4-8MF2 or
l
SWD4-(3/5/10) F8-24-2S (pre-terminated cable).
Do not connect the SmartWire-DT line to the
EASY-COM-SWD-… or disconnect it without first de-energizing the
