CAUTION!
Run signal and power wiring separately!
Signal and supply lines (power cables) must be laid out so that no malfunctions
due to capacitive and inductive interference can occur (EMC).
WARNING!
Labels on or inside the device alert people that dangerous voltage may be
present or that surfaces may have dangerous temperatures.
WARNING!
Splaying of strands can cause hazards!
During wiring of terminals with stranded conductors, splaying of strands shall be
avoided.
– Ferrules can be used to prevent splaying.
WARNING!
Removal/Insertion under power
The devices are not designed for removal or insertion under power. Because of
unforeseeable consequences, it is not allowed to plug or unplug devices with
the power being ON.
Make sure that all voltage sources (supply and process voltage) are switched
off before you
– connect or disconnect any signal or terminal block
– remove, mount or replace a module.
Disconnecting any powered devices while energized in a hazardous location
could result in an electric arc, which could create a flammable ignition resulting
in fire or explosion.
Make sure that power is removed and that the area has been thoroughly
checked to ensure that flammable materials are not present prior to proceeding.
The devices must not be opened when in operation. The same applies to the
network interfaces.
