2. SAFETY NOTICES

ATTENTION!
Switch off the Soft-Starter SSW-07/SSW-08 before installing the Modbus
RTU – RS-485 Kit.
The electronic boards have components that are susceptible to
electrostatic discharge. Never touch any of the electrical components
or connectors without following the proper grounding procedures. If it
is necessary to do so, touch the grounded heatsink or use a suitable
grounded wrist strap.

3. OPTIONAL MODULE DESCRIPTION

This optional module allows the Soft-Starter to communicate in a multipoint
RS-485 network of up to 1000m with Modbus-RTU protocol.The Modbus-RTU -
RS-485 kit is connected directly to the Soft-Starter. It is fitted into the front cover
slot for plug-in optional modules.The functions of the communication terminal
strip points and of the DIP switches are indicated on the module.
NOTE!
The terminal strip point identified by the symbol
internally through dule circuitry. A direct connection of this point to the
ground would be advisable in order to improve the electric conductivity
of the grounding. The figure 1 shows the RS-485 connections.
NOTE!
For more information refer to the SSW-07/SSW-08 Parameter Programming and
to the Serial Communication manual, available on the CD that comes with the
Soft-Starter module or at WEG's web site (www.weg.net).
