Strong electromagnetic sources such as power lines, large electric motors, switches or welding machines can cause strong elec-
tromagnetic interference. Video monitors and cables are also strong sources of interference.
If the cable must be routed through an area with considerable electromagnetic interference, shielded cables should be laid with
grounding at the signal source.
Avoid placing your signal cables parallel to a high voltage line! Lay the signal cable at right angles to the power line to minimize
unwanted effects.

The pin assignment of port 1/2 on page 8/9 in the original manual does not conform to the stan-
dards. The marking of pin 1 on the assembly print must be exchanged with pin 2.
Attention: If you connect directly to the post the original manual fits.
If a flat cable is plugged in, this pin assignment is valid.
