6.1.2 Wiring requirement of operating site
Note the following when wiring the operating site:
▪ Do not route lines which cause interference (e.g. supply lines) and lines
susceptible to interference (e.g. signal lines) in the same cable duct.
▪ Maintain a distance of more than 100 mm (3.94") between lines which
cause interference and those which are susceptible to interference.
Figure33: Recommended wiring
1 Cable duct for lines causing inter-
ference
3 Cable duct for lines susceptible to
interference
2 Line causing interference (e.g.
power line)
4 Line susceptible to interference
(e.g. signal line)
▪ Never connect the device with a multi-wire collective pipe.
▪ Use a shielded cable for transmitting the output signal.
6.2 Supply voltage
You may only connect the device to circuits with an external overcurrent pro-
tection device and an all-pole isolating device so that the equipment can be
fully de-energized if required.
