Connecting a power supply adapter

Input voltage options
The optional power supply adapter is available in two versions:
● Power supply adapter for 12 V DC direct voltage
● Power supply adapter for 110 - 230 V AC alternating voltage
Note
Applies only to SCALANCE W786-3xx
If a SCALANCE W786-3xx is operated with diversity for three antenna pairs, the power
for 12 V DC cannot be supplied redundantly. In this case, there is no further opening in
the housing for a second power cable.
How to fit the power supply adapter
WARNING
Danger from line voltage
Power supply cables may only be connected when the power is turned off!
Start up the SCALANCE W786 only after screwing the housing cover in place again so that
protection from touching live parts is restored!
