4.2.1.2 Data bus
If you are not using the bus cable available from LiquoSystems, make sure that this is suitable and
approved for the communicaon protocol Modbus.
4.2.1.3 Insulaon
Stripped strand ends must not be longer than approximately 10 mm. They must always be pro-
tected with wire end ferrules. Exposed strand ends must be shortened and properly insulated.
The stripped shield of the bus cable must not be laid bare, it must be properly insulated with
a shrink-on sleeve.
4.2.2 Roung the cable into the housing
Aenon!
Only use cables with a diameter of 5 – 13 mm. Otherwise, the seal of the
cable screw connecon will not be eecve.
¨Loosen the union nut of the cable screw connecon
suciently to allow the cable to be pushed through
easily.
¨Strip the required length of the cable: The cable
sheath should project so far into the inside of the
housing that the free strands can be readily laid to
the contact point.
¨Route the cable through the loosened cable screw connecon and into the housing.
¨Secure the cable against pulling when the cable sheath projects far enough into the housing:
–Tighten the union nut hand-ght.
–Remember that the cable should remain easy to rotate unl the strands are connected.
4.2.3 Connecng the strands
Aenon!
● Follow the recommendaons in the chapter “4.2.5Applicaons”on
page 13.
● Makes sure that the stripped strand ends are max. 10 mm long.
●Always protect the strand ends with wire end ferrules before you
connect them.
In the terminal of iFerm Nano Terminal, the individual contact points are unlocked with a sloed
screwdriver.

¨Insert the screwdriver into one of the square open-
ings and lt it slightly towards the centre of the ter-
minal in order to open the contact point suciently.
¨Push the strand end all the way into the corre-
sponding round opening.
¨Pull out the screwdriver and check whether the strand is secure in the terminal.
¨Repeat this procedure for all the required strands.
4.2.4 Installing the bus terminang resistor
Each end of a data bus line must be terminated by a 120 Ω bus terminang resistor. For this, both
connecons of the resistor are, like the strand ends of a cable, routed into a terminal.
A bus terminang resistor is already connected when the unit is delivered. However, this is only
required if iFerm Nano Terminal is installed at the end of the data bus line, see “4.2.5.4 Data bus
terminaon”onpage14. Otherwise you must remove the bus terminang resistor in order to
connect the second bus cable at this locaon. You then connect the resistor to the other, free end
of the data bus line.
4.2.5 Applicaons
The example graphics show the cable roung schemacally as a plan view. The following compari-
son is intended to show how the schemac representaon should be interpreted:

4.2.6 Aaching the connecng cables
¨Check that the connected strands are secure before you complete the installaon work and
close the iFerm Nano Terminal.
¨Securely ghten all cable screw connecons on the inside and outside in order to ensure strain
relief and no leaks.
Informaon
Even if you are not immediately integrang iFerm Nano Terminal into your
network or connecng it to an end device, you should make the device’s
internal Ethernet connecon straight away. This means that later on you
only have to insert an Ethernet cable into the plug of the cable screw con-
necon without having to open the device again.
¨When you are ng the housing cover, connect the short Ethernet cable in the device to the
Ethernet socket in the display. When doing so, take care above all not to break o the plug’s
latching tab when releasing the plug (press down the latching tab).
¨Close the housing and secure it with the quick-release fasteners.
Aenon!
If you open iFerm Nano Terminal again later, you must detach the Ether-
net cable in the device (when doing so, press down the plug’s latching tab
so that it does not break o).

inserted seal and a union nut.
¨Guide the Ethernet cable through the
union nut.
¨Insert the cable into the seal and guide it through the shank and the screw sleeve.
¨Insert the Ethernet cable into the socket on the housing.
¨First only loosely screw the union nut and the screw sleeve so that you can sll align them.
¨Screw the screw sleeve onto the cable screw connecon so that the seal slides into the union
nut inside the shank.
¨Tighten the screw sleeve, cable screw connecon and union nut suciently so that the seal
protects the screw connecon against dirt and splash water.
¨Connect the loose end of the Ethernet cable to your network. It might be necessary to change
the IP address of iFerm Nano Terminal in order to adapt it to your network (Global sengs
menu). Contact your system administrator or IT expert if necessary.

5 Operaon
This chapter contains instrucons on operang steps that are usually required during normal
operaon.
Inial operaon
For informaon on the inial set-up of iFerm Nano Terminal , read the
chapter “8 Commissioning” on page 51.
5.1 Notes on operaon
5.1.1 Concepts and illustraons
Since the actual display depends on the type and number of the connected devices, the screen-
shots used in these instrucons are only examples for illustrave purposes.
Since iFerm Nano Terminal can be operated via a network-capable end device or on the device
itself, no language dierenaon has been made in the instrucons: “Press ...” means that you
either touch the terminal’s touch screen with your nger or click on another input device.
5.1.2 General operang instrucons
Basically you can perform all inputs via the terminal’s touch screen or via the oponally available
Web interface funcon of an end device connected to the terminal. Perform the inputs on the
touch screen during the inial commissioning.
Informaon
Green areas are buons or input elds.
5.1.3 Buons
When performing an input via the terminal’s touch screen, touch the buons with your nger.
When performing an input via the Web browser of a connected end device, use the mouse or
touch pad in the usual way.

5.2 Protected areas
To prevent unauthorised persons changing sengs on the terminal, various areas are pass-
word-protected. The protected areas are divided up into a user level and a service level, whereby
the service password also incorporates the rights of the user level.
User level Level Rights
User 1The password applies to the user for dening global sengs.
Seer (installer) 2The password applies to the Seer level, in which the installer
acvates and deacvates the controller’s addresses.
Aenon!
The passwords cannot be changed!
The passwords are xed and cannot be changed. They must therefore
never be given out carelessly!
Informaon
If an error message covers the input window following an incorrect entry,
move this error message to the side:
¨Press once on the error message and once in an area of the screen in
which the error message does not disturb (e.g. boom le).
