2.2.2 Working Modes

The UPS has the following working modes:



Normal mode

When the mains is normal, the rectifier boosts the mains input voltage and converts the AC power into stable DC power for the inverter, and the mains charges batteries over a charger. Then the inverter converts the DC power into stable AC power, which is supplied to loads.



Battery mode When the mains is abnormal or disconnected, the DC-DC step-up transformer boosts the

DC power supplied from batteries. Then the inverter converts the DC power into stable AC power for powering loads.



Bypass mode The mains supplies power directly to loads after filtering. The UPS transfers to bypass

mode when overload, overtemperature, or faults occur. This mode does not provide battery backup capability.



Economy control operation (ECO) mode If the bypass voltage and frequency are in the specified range, the UPS supplies power to

loads over the bypass. If the bypass voltage and frequency are outside the range, the UPS transfers to normal or battery mode. ECO is short for economy control operation.



The UPS2000-G-15 kVA/20 kVA supports battery ECO mode only in the case of two mains inputs. In battery ECO mode, the bypass supplies power to the UPS, and batteries are used as backup power. If the bypass is abnormal, the UPS transfers to battery mode.



By default, ECO mode described in this document refers to mains ECO mode.

The UPS has no built-in backfeed protection device. You can install a backfeed protection device on the input front side.

If you do no install a backfeed protection device on the input front side, attach a warning label to the main power isolation device. The label reads like this: "This circuit supplies power to the UPS. Before cable connection, disconnect the UPS, and check the voltage across wiring terminals."

When battery mode is unavailable or the mains fails, the UPS internal voltages or energy may flow back directly, or through a leakage path, to an input terminal. To minimize the risk of electric shocks, install a backfeed protection device on the input side.

Table 3-3 lists the rated voltages and currents for backfeed protection contactors on the UPSs.
