Operating Modes
The CUPS system has various operating modes. Below are the available modes and a brief description:
Online Mode:
The CUPS will supply power to the load using the mains supply via
the internal charger/inverter. The mode is engaged when the mains supply voltage
is within range, the CUPS will provide pure and stable AC power to output using the
internal inverter output. The CUPS will also charge the battery during Online Mode.
Online Mode can be engaged manually (if in Bypass Mode) via front panel by pressing
the ON/MUTE button for 3 seconds. If the mains supply is lost, the CUPS will enter
Battery Mode.
ECO Mode (Energy Saving Mode):
The UPS will supply power to the load using
the mains supply directly. When the mains supply voltage is within range, the CUPS
will supply output power using the bypass input to save energy. The CUPS will also
charge the battery at ECO Mode.
Frequency Converter Mode:
When mains supply frequency is within 40 Hz to 70
Hz, the UPS can be set at a constant output frequency, 50 Hz or 60 Hz. The CUPS
will still charge the battery at Frequency Converter Mode.
Battery Mode:
The CUPS will supply power to the load using the batteries via the
internal inverter. The mode is engaged when the input voltage is out of range. The
Battery Mode Backup Timer will engage, displaying either the amount of time which
the battery can supply power to the load or the accumulated time. Refer to Section
4.18 for selections.
Bypass Mode:
The CUPS will supply power to the load using the mains supply
directly. The Bypass Mode will engage when mains supply voltage is within the
acceptable range and the CUPS is overloaded. The CUPS will also charge the battery
at Bypass Mode.
Bypass Mode can be engaged manually (if in Online Mode) via front
panel by pressing the OFF/ENTER button for 3 seconds.
Standby Mode:
The CUPS is powered off and no power will be present at the
output. The batteries will be charged during Standby Mode. Standby Mode can be
manually engaged (if in Online Mode) by pressing the OFF/ENTER button for 3
seconds.
Fault Mode:
When a fault has occurred, the ERROR icon and the fault code will be
displayed.
