• in dealing with dangerous voltages.
•in the use of specifications and standards.
In particular VDE- and accident preventation
regulations.
Use according to the rules
The RTU-COM module was developed, manu-
factured, tested and documented while ob-
serving the relevant standards. When observ-
ing the valid regulations for installation, com-
missioning and maintenance, the product
poses no danger to health and objects in nor-
mal case.
Use according to the rules means that the
RTU-COM module is operating and main-
tained exclusively in the form as described in
the functional- and module description docu-

WARNING CAUTIONS
Earth the devices
Before connecting any power to the de
vice, make sure that the earth terminal
is wired to protective earth. The earth
ing may be removed only if it is certain
that no more power is being supplied to
the device.
Regard the earthing principles for the
serial peripheral bus (direct or capaci-
tive earthing)
Connecting of the supply voltage
A terminal block feeding dangerous con-
tact voltages (supply, input/output chan-
nels should only be plugged or with
drawn in off load state.
• Protect the device from dampness,
dirt and damage during transport,
storage and operation.
• Do not operate device outside of the
specified technical data.
• Operate device according to the pro-
tection degree IP20 (DIN 40050)
Mount into a closed cubicle or rack if the
environmental conditions that requires.
• Do not obstruct the ventilation for
cooling
Do not cover the ventilation slots by cab-
les or wires.
• Lead signal - and power- lines
separately
Capacitive and inductive interferences
of the power lines to signal lines should
be prevented by appropriate cable lay
ing (distance, crossing).
• GSM Emission
There may be a hazard associated with
the operation of your GSM Modem close
to an adequately protected personal
medical devices such as hearing aids
and pacemakers. Consult the manufac
tures of the medical device to determine
if it is adequately protected.
• GSM Emission
Operation of your GSM Modem close to
other electronic equipment may also
cause interference if the equipment is
inadequately protected. Observe any
warning signs and manufacturers re-
commendations.
• Installation Personnel
Ensure that the installation has been per
formed by a qualified personnel.
