Operation
• The input terminal block requires the connection of the phase conductors in a "star"
arrangement (3 phase conductors plus a neutral conductor). It is forbidden to connect
the phase conductors in the "triangle" system (three phase conductors without a
neutral conductor).
• When connecting the phases, it is important to keep the correct sequence. Phase 1 to
1, 2 to 2, and 3 to 3. Otherwise, the safety system may disable the device.
• The "bypass" switch is the bypass switch of the stabilizer. When the AVR is operating
normally, the bypass switch should be off. When the device is damaged, turn off the
device with the power button and turn on the BYPASS mode. The device will supply
energy directly from the grid, bypassing the AVR electronics.
• When the delay button on the front panel is pressed, the device will delay the start for
180 seconds until the output signal is applied. The default time is 6 seconds.
• The button "Single-phase mode / three-phase mode" is used to select the operating
mode. By default, the device is set to three-phase mode. Pressing the button will
switch the device to single phase mode.
• In three-phase mode, the AVR will compensate for too high or too low an input voltage
and will output the stabilized voltage. If in this mode any of the phases does not work
properly or is not connected, the device will protect itself and will not supply voltage to
the output, informing about it by switching on the "PHASE ERROR" indicator.
• In single-phase mode, each phase can work independently, e.g. an error in phase 2
operation will not affect the operation of phase 1. The input voltage of each phase is
stabilized with 3% precision. The maximum power on each phase is approx. 1/3 of the
maximum nominal power of AVR (10KW).
Cleaning
