RELATED PRODUCTS
• PC configurator software (model: R8CFG)
Downloadable at M-System’s web site.
A dedicated cable is required to connect the module to the PC.  Please refer to the internet software download site or the users manual for the PC configurator for applicable cable types.
• Clamp-on current sensor (model: CLSE)
The clamp-on current sensors, not included in this product package, must be ordered separately. Required number depends upon the system configuration.
