1. Safety and EMC instructions All safety instructions in this document must be read, understood and followed. 1-1. Transportation and Storage Please transport the UPS system only in the original packaging to protect against shock and damage. The UPS must be stored in the room where the temperature is well regulated. Ambient temperature should not exceed 40°C. 1-2. Preparation Condensation may form if the UPS system is moved immediately from cold to warm environment. The UPS system must be absolutely dry before being installed. Please allow at least two hours for the UPS system to acclimate the...

Connection Warnings There is no standard backfeed protection inside of the UPS. However, there are relays on the Input to cut off line voltage and while the neutral is still connect to UPS. Input Rly Main Input Input Rly Main Input Bypass Input Input relay diagram Input relay diagram for dual-input model This UPS should be connected with TN grounding/earthing system. The power input for this unit must be three-phase rated in accordance with the equipment nameplate. It also must be suitably grounded. WARNING HIGH LEAKAGE CURRENT EARTH CONNECTION ESSENTIAL BEFORE CONNECTING SUPPLY Use of this equipment...

Do not disconnect the grounding/earthing conductor cable on the UPS or the building wiring terminals under any circumstance. A The UPS system features its own, internal current source (batteries). The UPS output sockets or output terminal blocks may be electrically live even if the UPS system is not connected to the building mains/live wires, (only for standard models) A In order to fully disconnect the UPS system, first press the "OFF" button and then disconnect the mains/live wires. Ensure that no liquid or other foreign objects can enter into the UPS system. The UPS can be operated by any...

2. Installation and Operation The whole series is equipped with dual inputs. This series came with two VAC systems: 208V and 400V. Please refer to the following table.___ We also offer optional parallel function for both models upon request. The UPS with parallel function is called the "Parallel model". We have detail installation and operation procedure of the Parallel Model in the following chapter. 2-1. Unpacking and Inspection package and check the package contents. The shipping package should contain: UPS user manual monitoring software CD RS-232 cable (option) USB cable parallel cable (only...

Installation and wiring must be carried out in accordance with the local electric laws and regulations by trained professionals. 1) Make sure that the mains wire and breakers of the building are rated for the capacity of the UPS to prevent electric shock or risk of fire. NOTE: Do not use the wall receptacle as the input power source for the UPS, as its rated current is less than the UPS's maximum input current. The receptacle may be damaged and destroyed. 2) Switch off the mains switch in the building before installation. 3) Turn off all the connected devices before connecting to the UPS. 4)...

NOTE 2: Please install the output breaker between the output terminal and the load, and the breaker should have leakage current protective function if necessary. 6) Put the terminal block cover back at the rear panel of the UPS. Warning: ● Make sure a DC breaker or other protective device between UPS and the external battery pack is installed for added safety. If not, please install it...

2-4. UPS Installation for Parallel System If the UPS is only for single operation, you may skip this section. 1) Install and wired the UPS according to the section 2-3. 2) Connect the output wires of each UPS to an output breaker. 3) Connect all output breakers to a major breaker. This major output breaker will then connect directly to the loads. 4) Either common battery packs or independent battery packs for each UPS are allowed. 5) Refer to the following wiring diagram: Wiring diagram of parallel system for HV 30KL/40KL and LV 15KL/ 20KL Wiring diagram of parallel system for HV 60KL and LV...

Input and battery information Output and load information

1) After power mains is connected correctly, set the breaker of the battery pack to "ON" position. Then set the line input breaker to "ON" position. At the same time, the fan will start running and the UPS will start initialization. After a few seconds, the UPS will supply power to the loads via the Bypass mode. NOTE: When UPS is in Bypass mode, the output voltage will be directed from mains after you switch on the input breaker. In Bypass mode, the load is not protected by the UPS. To protect your precious devices, you should turn on the UPS. Refer to next step. 2) Press and hold the "ON" button...
