ModBUS CONNECTION RULES
1) Install the modules in the DIN rail (120 max)
2) Connect the remote modules using cables of an appropriate length. The following table shows cable length data:
-Bus length: maximum length of the Modbus network according to the Baud Rate. This is the length of the cables that connect
the two farthest modules (see Diagram 1).
-Derivation length: maximum length of a derivation 2 m (see Diagram 1).
Ld
For maximum performance, it is recommended to use special shielded cables, such as BELDEN 9841.

INSTALLATION REGULATIONS
The module has been designed for vertical installation on a DIN 46277 rail. For optimal operation and long life, adequate
ventilation must be provided. Avoid positioning ducting or other objects that obstruct the ventilation slots. Avoid mounting
modules over heat-generating equipment.
Installation in the bottom part of the electrical panel is recommended.
These are open type devices intended for installation in a nal casing/panel that offers mechanical protection and protection
against the spread of re.

Power supply
Terminals 2 and 3 can be used to provide the module with power supply as an alternative to
the connection using the Z-PC-DINx bus.
Power voltage must be between 10 and 40Vdc (any polarity) or between 19 and 28Vac.
The upper limits must not be exceeded in order to avoid serious damage to the module.
If the power supply source is not protected against overload, a safety fuse with a 1A max
permissible value must be installed in the power supply line.
RS232 serial port
The module has a serial port that can be congured with the SW2 switch.
The illustration shows how to complete connections.
The RS232 interface is fully settable.
RS485 serial port
The module has a serial port that can be congured with the SW2 switch.
The illustration shows how to complete connections.
N.B.: the indication of the RS485 connection polarity is not standardised and in some
devices may be inverted.
