17. If communications are adversely affected by noise from the Unit's power
supply terminals, the problem may be solved by implementing the mea-
sures shown below.
a) Add to the communications retry processing at the application. In par-
ticular, noise resistance capacity can be improved by increasing the
number of retries for applications using UDP.
b) Insert a noise filter right next to the Unit's power supply terminals.

As close as possible
Recommended filter: MAS-1206-33 by Nemic-Rambda K.K.
