2.2.2 Working Modes

The UPS has the following working modes:

 Normal mode

UPS2000-G-(6 kVA-20 kVA)

User Manual

2 Quick Introduction

Issue 13 (2019-05-05)

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.

User Manual

3 Installation

Issue 13 (2019-05-05)

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.

 The bypass frequency range is associated with the ECO frequency range (the bypass frequency

range is ±0.5 Hz, ±1 Hz, ±2 Hz, ±3 Hz, ±4 Hz, ±5 Hz, or ±6 Hz; the ECO frequency range is ±0.5

Hz, ±1 Hz, ±2 Hz, or ±3 Hz).

The bypass frequency range must be greater than or equal to the current ECO frequency range (if the

ECO frequency range is ±3 Hz, the bypass frequency range is ±3 Hz, ±4 Hz, ±5 Hz, or ±6 Hz).

The ECO frequency range must be less than or equal to the current bypass frequency range (if the

bypass frequency range is ±1 Hz, the ECO frequency range is ±0.5 Hz or ±1 Hz).

 The voltage level is associated with the upper threshold for bypass voltages (10%, 15%, 20%, 25%,

or 30%).

If the voltage level is 220 V (line voltage: 380 V), the upper threshold for bypass voltages is 10%,

15% (default), 20%, or 25%.

If the voltage level is 230 V (line voltage: 400 V), the upper threshold for bypass voltages is 10%,

15% (default), or 20%.

If the voltage level is 240 V (line voltage: 415 V), the upper threshold for bypass voltages is 10% or

15% (default).
