MODBUS and CANOPEN connection standards
1) Install the module into the DIN rail.
2) Please use a cable with a suitable length to connect the remote modules.
The following table show the cables length.
- Bus Length: Modbus network maximum length as a function of the Baud rate.
This is the length of the cables which connect the two bus terminators modules.
- Derivation Length: Derivation line Maximum length as a function of the Baud Rate
(see Scheme 1).
In order to obtain maximum performances it’s recommended to use a specific shielded
cable, as an example BELDEN 9841.

Installation Rules
The module is designed to be installed, in vertical position, on
rail. In
DIN IEC EN 60715
order to ensure optimum performance and a longest working life, the module(s) must be
provided with adequate ventilation and no raceways or other objects that obstruct the
ventilation slots.
Never install the modules near heat sources
.
We recommend installation in the lower part of the control panel.
Inserting on the DIN rail
As the picture shows:
1) Insert the module rear IDC10 connector
on a DIN rail free slot (there’s only one
way to insert the module because of
polarized connector).
2) Push the two locks placed at the sides
of the rear IDC10 connector to fix the
module.
