6. Special Function

The series UPS has some special functions, which could satisfy some special application of user. And the functions have own features, please contact your local distributor for further information before using the function.

6.1 HE Function

6.1.1 Brief introduction of HE function

If HE function is set to enable, after the UPS is turned on, the power used by the load is directly supplied from the mains power via internal filter while the utility power is in normal range, so the high efficiency could be gained in HE mode. It is also called economy mode. Once the mains power is loss or abnormal, the UPS would transfer to Line mode or Battery mode and the load is supplied continuously. The great virtue is overall high efficiency ≥ 0.96 of UPS, to save power for user. But the disadvantage is 1) the load can not be protected as well as in Line mode, for the load is directly supplied from the mains; 2) the transfer time of UPS output from HE mode to Battery mode is about 10ms. So the function is not suitable to some sensitive loads, and the region where the mains power is unstable.

6.1.2 Set the function

The function could be enabled through the LCD setting in Bypass mode. Enter the power strategy setting menu by following chapter of 5.4.7.

6.2 Converter Function

6.2.1 Brief introduction of Converter function

In converter mode, the UPS would free run with fixed output frequency (50Hz or 60Hz). Once the mains power is loss or abnormal, the UPS would transfer to Battery mode and the load is

supplied continuously. The great virtue is the output frequency is fixed, which is required by some very sensitive loads. But the disadvantage is the load capacity of UPS should be derated to 60% in converter mode.

6.2.2 Set the function

The function could be enabled through the LCD setting in Bypass mode. Enter the power strategy setting menu by following chapter of 5.4.7.

6.3 Parallel Function

6.3.1 Brief introduction of the redundancy

N+X is currently the most reliable power supply structure. N represents the minimum UPS number that the total load needs, X represents the redundant UPS number, i.e. the fault UPS number that the system can handle simultaneously. When the X is larger, the reliability of the power system is higher. For occasions where reliability is highly depended on, N+X is the optimal mode.

As long as the UPS is equipped with parallel cables, up to 4 UPSs can be connected in parallel to realize output power sharing and power redundancy.

6.3.2 Parallel installation and operation

How to install a new parallel UPS system:

1) Before installing a new parallel UPS system, user need to

prepare the input and output wires, the output breaker, and the parallel cable.

2) Users need to use a standard 25-pin communication cable,

which should have 25 cores, corresponding stitches and shield, as the UPS parallel cable. The length of the parallel cable is appropriate to be less than 3m.

3) Remove the cover plate of the parallel port on the UPS,

connect each UPS one by one with the parallel cable, and re-screw the Parallel port cover which is supplied in the accessories.

4) Strictly follow the chapter of 4, the wiring requirement of single

UPS to perform the wiring of each UPS.

5) Connect the output wires of each UPS to an output breaker

panel.

6) Disconnect the Jumper on JP1 and JP2 of the terminal block

first, and connect each output breaker to a main output breaker and then to the loads.

7) Each UPS need an independent battery pack.

8) Please refer to the wiring diagram in the following diagram.

9) The distance between the UPSs in parallel and the breaker

panel is required to be less than 20 meters. The difference between the wires of input and output of the UPSs is required to be less than 20%.
