EMOVAL FROM THE CYLINDER
1. Unscrew the four M6 bolts (bolt A, Figure 4)
2. Remove the CIMSmart for the adapter ring (some force may be required because of the o-
ring).

IRING
A shielded twisted pair cable with 3x2 or 4x2 twisted pairs (minimum 0.25mm
3x2 cable, the diagnostic and monitoring functionalities cannot be used and, therefore, is not
recommended.
Losses in a transmission line are a complex combination of DC conductor loss, AC loss due to skin
effect, leakage and losses in the dielectric. It is therefore very important to select the appropriate
cable, like the one selected and delivered specially for CIMS:
Super-Paar-Tronic 340-C-Pur 4x2x0.25 (R987398724).

The cable consists of four twisted pairs (4x2x0.25). The cable has an overall shielding from tinned
copper braiding and a full polyurethane outer jacket. The cable is suitable for both inside and
outside use, as it is resistant to weather, ozone and UV-radiation, furthermore it has a very good oil
resistance.

ABLE TERMINATION
The proper termination of the cable is very important. If the cable is not terminated with its
characteristic impedance, distorted waveforms will result. Normally using 120 resistors for cable
termination is adequate, as shown in Figure 15. Note that the Modbus output already has a 120
resistor integrated, so an additional resistor at the receiver side is not necessary. This, however,
implies that only one single CIMSmart unit can be connected to a Modbus client.
