3. Installation

Warning
The CIM 1XX must only be connected to
SELV or SELV-E circuits.

3.1 Connecting the LON

Grundfos recommends to use a cable according to
Echelon standards.
Examples of recommended cable types
• Belden 85102
• Belden 8471
• Level IV, 22 AWG
• JY(St) Y 2 x 2 x 0.8
• TIA Category 5.
A LON network must be terminated. The termination
depends on the network topology chosen.
Fitting the cable
Procedure:
See fig. 2.
1. Connect the conductors to terminal A (pos. 1).
2. Connect the conductors to terminal B (pos. 2).
3. Connect the twisted screen ends to terminal
"Screen" (pos. 3).
The screen must only be connected to the
screen terminal of the CIM 1XX LON
module. See fig. 2, pos. 3.
Note
The cable screen must never be
connected to earth via the earth clamp.
See fig. 2, pos. 4.
The stripped part of the cable screen must
Note
be as short as possible to reduce the
impedance at high frequencies.
