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 communication protocol Modbus .
4.2.1.3 Insulation
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 Routing the cable into the housing
Attention!
Only use cables with a diameter of 5 – 13 mm. Otherwise, the seal of the
cable screw connection will not be effective.
¨
Loosen the union nut of the cable screw connection
sufficiently 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 connection and into the housing.
¨
Secure the cable against pulling when the cable sheath projects far enough into the housing:
–
Tighten the union nut hand-tight.
–
Remember that the cable should remain easy to rotate until the strands are connected.
4.2.3 Connecting the strands
Attention!
● Follow the recommendations in the chapter “4.2.5 Applications” 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 slotted
screwdriver.
