ModBUS CONNECTION RULES
- Install the modules in the DIN rail (120 max)
- 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).

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.
CAUTION
These are open type devices intended for installation in a final casing/panel that offers mechanical protection and protection against the spread of fire.
CAUTION
To configure the device via the Easy Setup software, the master device must be switched off.
ELECTRICAL CONNECTIONS
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 configured 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 configured 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.
Power supply and Modbus interface are available using the Seneca DIN rail bus, via the IDC10 rear connector, or the Z-PC-DINAL2 accessory.
