The following settings are related to the characteristics of the local network. They are used by the measurement functions of the MicroLogic X control unit. These settings have no effect on protections.
Available settings include: 208 V / 220 V / 230 V / 240 V / 380 V / 400 V / 415 V / 440 V / 480 V / 500 V / 525 V / 550 V / 575 V / 600 V / 660 V / 690 V / 1,000 V.
Default = 400 V.
The rated voltage can be set as follows:
oOn the MicroLogic X display screen, at Home > Configuration > Network > Nominal Voltage
oWith EcoStruxure Power Commissionsoftware
Available settings are:
o50 Hz
o60 Hz
The rated frequency can be set as follows:
oOn the MicroLogic X display screen, at Home > Configuration > Network > Nominal Frequency
oWith EcoStruxure Power Commissionsoftware
After changing the rated frequency setting, the MicroLogic X control unit must be restarted for the new setting to be taken into account.
Restart the MicroLogic X control unit in one of the following ways:
oSwitch off the power supply to the MicroLogic X control unit, and switch it back on.
oClick the Restart Module button on the Launch Firmware Upgrade page of EcoStruxure Power Commission software.
The VT ratio is the ratio between the primary and the secondary rated voltages as measured by a voltage transformer (VT).
The value range for the primary voltage (VT in) is from 100–1,250 in increments of 1 (factory setting: 690).
The value range for the secondary voltage (VT out) is from 100–690 in increments of 1 (factory setting: 690).
The primary and secondary voltages can be set as follows:
oOn the MicroLogic X display screen, at Home > Configuration > Network > VT Ratio
oWith EcoStruxure Power Commission software
