2-20 Installation
1560D-UM051D-EN-P – February 2005
Converter Modules The Bulletin 825 converter module provides three-phase current feedback
to the SMC Dialog Plus™ controller for metering and overload protection
during bypass operation. Cat. No. 825-MCM20 is to be used with current
transformers.
The current transformer ratio must be programmed in the calibration group
for proper current measurement scaling. See page 5-2 for instructions on
programming this parameter.
Figure 2.7 shows the connection between the controller and the module.
