24VAC/DC A+ B-GNDThe W-Modbus units have 24 VAC/VDC power in/out connection and con-nection for Modbus RTU communication via RS485.WARNING: When powering the W-Modbus device using 24 VAC, thepower supply/transformer should not be shared with another Modbus de-vice also sharing a RS485 connection. This is to avoid ground loops causedby the use of different types of rectification in the devices. W-Modbus usesfull wave rectification.Install the W-Modbus unit next to the device it should be connected to.APPLICATION AREAThe W-Modbus product transmits Modbus RTU frames wirelessly. It is de-signed to be used indoors as a Modbus RTU cable replacement.GENERALAll relevant personnel must acquaint themselves with these instructionsbefore installation. Warranty is subject to void if the product is not hand-led accordingly with the outlined instructions. Any damage to the productor parts due to improper handling will void the warranty.

Everydevice can act as either a Gateway or a Node, selectable by the 3 poleswitch - see Commissioning section.Each W-Modbus Node will scan to find the connected Modbus Servers’Modbus address. The scanning is done by querying each Modbus address,hence the process may take up to 2 minutes.

All instructions below apply to both models.W-MODBUS PRO1. Confirm that the W-Modbus unit has no visible damage.2. The W-Modbus enclosure is wall mounted and fits onto a junctionbox. Start with mounting the backplate of the enclosure.3. Connect the power supply and the Modbus device to the W-Modbusunit, as shown to the right. Use the rear and/or top knockouts forcable entry.4. All W-Modbus units are factory set for Node operation, without theneed for additional configuration. If mixing serial configuration in thesystem, adjust the dip switches accordingly.5. Secure the front plate to the mounted back plate.6. Check that the W-Modbus unit and its wiring are securely mounted (ifthe unit is powered this will be indicated by the LEDs)The device is now ready for commissioning.The label on the back of the product shows the product type:W-Modbus or W-Modbus PRO. |
