2. 2 Safety measures
When operating electrical devices, specific
parts of these devices inevitably carry
dangerous voltage. As a result, serious bodily
harm or property damage can occur if they
are not handled correctly.
WARNING
Electrical voltage!
Dangerous voltages can cause serious
bodily harm or death.
Therefore, please note the following:
• Before connecting the device, ground
it at the ground wire connection if
available.
• Dangerous voltages may be present
in all circuit parts connected to the
voltage supply.
• There may still be dangerous voltages
present in the device even after it is
disconnected from the supply voltage.
• Fit wire end ferrules on the conductors
made of individual wires.
• Only connect screw-type terminals
with matching numbers of poles and
of the same type.
• De-energize the system before
starting work.
WARNING
Risk of injury due to improper use
If the device is not operated according to
the documentation, protection is no longer
guaranteed and danger can emanate from
the device.
2. 3 Qualified personnel
This device must only be operated and
maintained by qualified experts.
Qualified experts are persons who, based
on their appropriate training and experience,
are capable of recognizing risks and avoiding
potential hazards which can arise during
operation or maintenance of the device.

3. 1 Incoming goods inspection
The prerequisites for smooth and safe
operation of the device include proper
transport, storage, setup and assembly,
as well as proper operation and maintenance.
Exercise caution when unpacking the device
without using force and only using suitable
tools.
Perform a visual inspection of the device to
ensure the fault-free mechanical condition.
Please check the scope of delivery for
completeness before beginning with the
installation of the device.
If you assume that safe operation is no
longer possible, the device must be shut
down immediately and prevented from
unintended re-commissioning. If you assume
that safe operation is no longer possible,
when, for example, the device:
• has visible damage,
• no longer functions despite an intact
power supply,
• was subjected to extended periods
of unfavorable conditions (e.g. storage
outside of the permissible climate
thresholds without adjustment to the room
climate, condensation, etc.) or transport
stress (e.g. falling from an elevated
position, even without visible external
damage, etc.).
3. Intended use

NOTE
Since the analogue-resistive touch screen
is not multi-touch capable, a mean value is
generated when the screen is touched in
multiple places simultaneously.
This averaged position value is evaluated by
the application. Therefore, since the entire
touch area is larger than the display itself,
multiple touches (including outside of the
display) can trigger undesired commands.
This can take place when the operator
holds the JPC70 in their hands.

6. 1 Connection to a master device
The device is connected via Ethernet to the
gateway device / master device of a bus
system:
6. Installation
6. 2 Disconnectors
Provide a suitable disconnector for the
supply voltage in the building installation in
order to de-energize the device from current
and voltage.
• Install the disconnector near the device in
a location that is easily reachable for the
user.
• Mark the switch as a disconnecting device
for this device.
6. 3 Supply voltage
A supply voltage is required for operation of
the device. Refer to the technical data for the
type and level of the supply voltage for your
device.
The connection of the supply voltage is made
via the plug-type terminals on the rear side of
the device.
Before connecting the supply voltage,
ensure that the supply voltage matches the
specifications form the technical data.

Connect the supply voltage via
a UL/IEC-approved fuse.
After connecting the supply voltage,
a display appears. If no display appears,
check whether the supply voltage is within
the rated voltage range.
WARNING
Risk of injury due to electric voltage!
It may result in serious bodily harm or death
due to:
• Touching live exposed or stripped cores.
• Device inputs that are dangerous to
touch.
Therefore, please note the following:
• The inputs for the supply voltage are
dangerous to touch.
• De-energize your system before
beginning to work!

6. 4 Bus structure
• All devices are connected in a bus
structure (line).
• Each device has a dedicated address
within the bus.
• Up to 32 participants can be connected
in a segment.
• The cable is terminated with resistors
(bus terminator, 120 Ohm, 1/4 W) at the
start and end of a segment.
• Repeaters (regenerative repeaters) must
be used for more than 32 participants in
order to connect the individual segments.

• Devices with an activated bus terminator
must be supplied with power.
• We recommend only placing the master
at the end of a segment.
• If the master is replaced with bus
terminator activated, the bus is
deactivated.
• If a slave is replaced with bus terminator
activated or is de-energized, the bus can
become unstable.
• Devices which do not participate in the
bus terminator can be replaced without
making the bus unstable.
