Warning notice system
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
indicates that minor personal injury can result if proper precautions are not taken.
NOTICE
indicates that property damage can result if proper precautions are not taken.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.

1.1
Product description
The SIMATIC Mobile Client900RFN is a portable HMI device with a rugged and ergonomic
design. A high-performance processor and Ethernet capability mean the device is excellently
suited to a wide range of uses. The device is lightweight and robust, has an easy-to-read
display and can be operated by both left-handed and right-handed users.
The device also has the following additional features:
●Ethernet, integrated with connecting cable
●9" TFT screen with color depth of 24 bits
●USB port for service purposes
●Heating system
The device heats up, if necessary, and keeps the internal temperature within the optimum
temperature range for as long as the heat output permits.
The SIMATIC Mobile Client connection box, connection box for short, is designed to be
mounted to the wall of the control cabinet. It provides the power supply and control system
connections in the control cabinet. The device is connected to the connection box with a
connecting cable.
The device is used as a mobile handheld terminal. The connecting cable can be easily
connected and disconnected at both the connection box and the handheld terminal. The
device enables you to use text- or graphic-based projects even more efficiently for simple
and medium-complexity operator control and monitoring tasks on machines and systems.

•Do not mount the wall bracket on doors or covers.
•Do not fit the wall bracket anywhere where the device may fall out of the bracket.
Note
The wall bracket is designed for fixed used and is always to be screwed to the wall.
•
The wall bracket should not be used to store tools or for other purposes.
•
Ensure that the wall bracket is used correctly. If the wall bracket is not in use, it should be

Magnetic wall bracket
The magnetic wall bracket provides a safe hold for the SIMATIC Mobile Client when used in
stationary mode.
The magnetic wall bracket is equipped with magnets for permanent or temporary mounting
on ferromagnetic surfaces. The following applies to the magnetic holding power:
●Under normal circumstances, the wall bracket can be removed from the surface without
tools.
●When the wall bracket is used as intended, there is no danger of it falling unintentionally
with the HMI device.
The magnetic wall bracket features a retaining mechanism for the HMI device.

Safety information on the magnetic wall bracket
CAUTION
Risk of injury when device drops
The magnetic wall bracket should be regarded as a suspended load and can fall. However,
under normal circumstances and if handled properly, the magnetic wall bracket is designed
in such a way that there is no risk of the wall bracket and device unintentionally falling and
the wall bracket can be taken down without tools.
In the case of improper locking, the device could fall out of the wall bracket.
•Never stand below the fitted wall bracket.
•Do not mount the wall bracket overhead or in places where the wall bracket or the
device held in it could fall.
•The wall bracket is permitted for indoor use only.
•Do not mount the wall bracket on doors or covers.
•The magnetic holding power is affected by the material, thickness and structure of the
mounting surface. Ensure that the holding power at the mounting location is sufficient. If
necessary, choose a different mounting location.
Risk of injury or damage from magnetic fields
Strong magnetic fields attract magnetic parts and damage or destroy electromagnetic
elements and devices. This also applies to pacemakers.
•Do not bring any iron parts (tools, nails, knives) into the vicinity of the magnets.
•Keep electronic devices and magnetic data carriers away from the magnets.
•Do not process the magnets mechanically, for example, by sawing or drilling.
•Keep the magnets away from open heat and flames.
Note
•
The wall bracket should not be used to store tools etc.
•
Ensure that the wall bracket is used correctly. If the wall bracket is not in use, it should be
stored in a suitable location.
•
Make sure that no one can trip over the cable and cause the device to fall.
Adjustable inclination
The inclination can be adjusted in the range from almost parallel to almost perpendicular to
the mounting surface. To adjust the inclination, loosen the wing screws located on both sides
of the wall bracket. With very large inclinations, the device cannot be removed from the wall
bracket. In this case, reduce the inclination in order to remove the device safely from the wall
bracket.
CAUTION
Tighten the wing screws sufficiently
Loosen the wing screws only when you wish to adjust the inclination. Afterwards, tighten
the two wing screws. Check that the wing screws and the device are tightly in place.

Protective cover
The protective cover provides mechanical protection of the display and is attached to both
handles. It protects the device from being damaged when transported, for example, in a tool
bag together with other tools.
NOTICE
Overheating
If you use the protective cover when the HMI device is on, the device may overheat.
Make sure the HMI device is off before you fit the protective cover.
Damage to the touch screen
Particles of dirt can scratch the touch screen when you attach the protective cover.
Clean the touch screen before attaching the protective cover or use a protective sheet
according to chapter "Protective foil (Page 18)".
