For maximum performance we recommend the use of special shielded cables, such as
the BELDEN 9841.
Installation rules
The module is designed to be installed in vertical position on a

order to ensure optimum performance and the longest working life, the module(s) must be
supplied with adequate ventilation and no raceways or other objects must obstruct the
ventilation slots Never install modules above sources of heat; we recommend installation in

Connection rules for ModBUS
1) Install modules in the DIN rail
2) Connect the remote modules using cables of proper length.
The following table shows the data for length of cables:
-Bus length: maximum length of the MODBUS network. This is the
length of the
total
cables that connect the two modules on which the bus termination has been inserted.
-Derivation Length: maximum length of a derivation.
