INSTALLATION REGULATIONS
The module has been designed for vertical installation on a DIN 46277 rail. For optimal operation and long life, adequate ven-
tilation 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.
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.
- Derivation length: maximum length of a derivation 2 m.
For maximum performance, it is recommended to use special shielded cables, designed specically for data communication.
IDC10 CONNECTOR
Power supply and Modbus interface are available also using the Seneca DIN rail bus, via the IDC10 rear connector, or the
Z-PC-DINAL2-17.5 accessory.
Back connector (IDC 10)
The illustration shows the meanings of the various IDC10
connector pins if signals are to be sent via them directly.
