GK7000 / GK7600
Working safely
A module must not be directly connected to the power supply system. The sup­
ply voltage for GK7000 must be 10…24 V DC and for GK7600 11…36 V DC.
Error messages must only be acknowledged once the cause of the error has
been eliminated and the danger no longer exists.
The device complies with the safety requirements of DIN EN 61010 Part 1
(VDE 0411 Part 1).
To ensure adequate immunity from interference, the bus lines must be
shielded cables.
The power supply connection cables always need to be shielded.
When connecting the cables (attaching and detaching terminals), action must
be taken to prevent electrostatic discharge which could damage the electron­
ics.
The GK7000 / GK7600 must be operated on a safety extra-low voltage (supply
voltage for GK7000 10
…
24 V DC and for GK7600 11…36 V DC), which usu­
ally supplies power to one or more consumers within a control cabinet.
Should the device be operated on a dc voltage network
1)
, additional precau­
tions must be taken to discharge excess voltages.
Automation equipment and devices must be covered over in such a way that
adequate protection or locking against unintentional actuation is provided (such
as access checks, password protection, etc.).
When devices are working in a network, these networks must be designed in
such a way that malfunctions in individual nodes can be detected and shut
down.
Safety precautions must be taken both in terms of hardware and software, so
that a line break or other interruptions to signal transmission, such as via the
bus interfaces, do not cause undefined states or loss of data in the automation
device.
1)
Distribution system for electrical energy with greater spatial expansion (e.g. over a number of
control cabinets) that may even supply consumers with large nominal currents.
