prerequisite for reliable protection of the motor and economic operation of the installation.
Follow the procedures in this section to ensure that programming and setup are correct.
• Current Converter (Cat. No. 825-MCM)
• Verify that the device’s current range lies within the full load or the service current
• Primary Current Transformer (if used)
• The transformer rating must be greater or equal to the full load or the service
current.
• The current ratio must be ___ A/1 A or ___ A/5 A for use with Cat.
No. 825-MCM2 or 825-MCM20 current converters, respectively
• Core Balance Current Transformer
• Verify that the output current of the core balance current transformer is
5…500 mA for the alarm or trip signal.
• Basic Unit (Cat. No. 825-M…)
• Verify that the power supply voltage has been properly selected for the control
circuit voltage.
• Verify that the appropriate option cards have been installed.
