WARNING
This is a Class A product. In a residential environment, this equipment may cause radio interference. In this case, the user may have to take adequate countermeasures.
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.
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.
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.
- Derivation length: maximum length of a derivation 2 m.
For maximum performance, it is recommended to use special shielded cables, designed specifically 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-DINAL1-35. 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.
ELECTRICAL CONNECTIONS
CAUTION
Switch the module off before connecting inputs and outputs.
To meet the electromagnetic immunity requirements:’
- use shielded signal cables;
- connect the shield to a preferential instrumentation earth system;
- separate shielded cables from other cables used for power installations (transformers, inverters, motors, etc.).
SETTING THE DIP-SWITCHES
WARNING
The DIP-switch settings are read only at boot time. At each change, perform a restart.
For use and settings via DIP-SWITCH SW1 see the user manual available on the website on the web page dedicated to the product.
SW2 DIP SWITCH SETTING: (Z-TWS4-RT ONLY):
Through DIP SWITCH SW2 it is possible to select RS485 or CAN communication through the IDC10 connector:
