Transferring To Bypass Mode; Setting Eco Mode - Huawei UPS5000-S-600 kVA User Manual

UPS5000-S-600 kVA
User Manual (Singapore, Three-phase, Three-wire)
Procedure
Step 1 Check that the cables between the UPS and the lithium battery cabinet are
properly connected.
Step 2 Open the upstream mains input and bypass input switches.
Step 3 Power on the lithium battery cabinet. For details, see the user manual for the
lithium battery cabinet.
Step 4 Use a multimeter to measure the voltages of the positive and negative battery
strings connected to the UPS battery input terminals. If the measured values are
consistent with the voltages displayed on the System Status screen of the lithium
battery cabinet, the batteries are properly connected.
Step 5 Check that the green indicator on the battery control unit in the lithium battery
cabinet blinks at 1 Hz or is steady on. Then, press and hold down the BATT START
button on the bypass module for at least 2 seconds. The system automatically
enters the battery cold start status. The LCD displays the Huawei logo and an
initialization progress bar.
Step 6 After LCD initialization, start the inverter on the LCD.

5.4 Transferring to Bypass Mode

Before shutting down the inverter, ensure that the bypass is normal. If the bypass
is not normal, after the inverter is shut down, the UPS supplies no power, and the
loads shut down.
Shut down the UPS inverter. Shut down the inverter on the LCD or WebUI, and the
UPS transfers to bypass mode.

NO TICE
NO TE
If the inverter is shut down when the input voltage or frequency exceeds the specified
threshold, the UPS supplies no power, and the loads shut down.
The UPS is set to non-ECO mode by default. Set the UPS to ECO mode when
energy saving is required.
In ECO mode, the bypass takes priority over the inverter in supplying power. If
the bypass is disconnected, the UPS transfers to normal mode. The transfer
time is less than 2 ms under typical working conditions and less than 10 ms
under poor working conditions.
