MASTER SERIES 3P/3P
2. Installation and Operation
There are two different types of online UPS : standard and long-run models.
Please refer to the following model table.
rated current is less than the UPS’s maximum input current. Otherwise the
receptacle may be burned 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) Prepare wires based on the following table (reference only, subject to electrical
consultant approval) :
NOTE :
1. The cable for 10KVA should be able to withstand over 40A current. It is recommended
to use AWG 10 or thicker wire for Phase and AWG 8 or thicker wire for
Neutral for safety and efficiency.
2. The cable for 20KVA should be able to withstand over 63A current. It is recommended
to use AWG 8 or thicker wire for Phase and AWG 6 or thicker wire for Neutral for
safety and efficiency.
3. The selections for color of wires should be followed by the local electrical
laws and regulations.
Warning :
1. For standard model.
- Make sure the UPS is not turned on before installation. The UPS should not be turned on
during wiring connection.
- Do not try to modify the standard model to the long-run model. Particularly, do not try
to connect the standard internal battery to the external battery.
- The battery type and voltage may be different. If you connect them together, it maybe
causes the hazard of electric shock or fire!
2. For long-run model.
- Make sure a DC breaker or other protection device between UPS and external
battery pack is installed. If not, please install it carefully. Switch off the battery
breaker before installation.
- NOTE: Set the battery pack breaker in “OFF” position and then install the battery pack.
- Pay highly attention to the rated battery voltage marked on the rear panel. If you want
to change the numbers of the battery pack, please make sure you modify the
setting simultaneously. The connection with wrong battery voltage may cause
permanent damage of the UPS. Make sure the voltage of the battery pack is correct.
- Make sure the protective earth ground wiring is correct. The wire current
spec, color, position, connection and conductance reliability should be checked
carefully.
- Make sure the utility input & output wiring is correct. The wire current spec,
color, position, connection and conductance reliability should be checked carefully.
Make sure the L/N site is correct,not reverse and short-circuited.
5) Remove the terminal block cover on the rear panel of UPS. Then connect the wires according to the following terminal block diagrams: (Connect the earth wire first when making wire connection. Disconnect the earth wire last when making wire dis
connection!)
For dual input unit, if there is two separate input, connect the Line input and bypass input respectively; if there is only one common input, please connect the line input and bypass input together.
NOTE :
1. Make sure that the wires are connected tightly with the terminals.
2. Please install the output breaker between the output terminal and the load, and the
breaker should be qualified with leakage current protective function if necessary.
6) Put the terminal block cover back to the rear panel
of the UPS.
2-4. UPS Installation for Parallel System
If the UPS is only available for single operation, you may skip this section to the next.
1) Install and wires the UPSs 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 output breaker. Then this major output breaker
will directly connect to the loads.
4) Each UPS is connected to an independent battery pack.
NOTE : The parallel system can not use one battery pack.Otherwise, it will cause system permanent failure.
5) Refer to the following wiring diagram :
2-5. Software Installation
For optimal computer system protection, install UPS monitoring software to fully configure UPS shutdown.
2. Installation and Operation
There are two different types of online UPS : standard and long-run models.
Please refer to the following model table.
We also offer optional parallel function for these two types by request. The UPS with parallel function is called as “Parallel model”. We have described detailed installation and operation of Parallel Model in the following chapter.
2-1. Unpacking and Inspection
Unpack the package and check the package contents. The shipping package contains:
● One UPS
● One user manual
● One monitoring software CD
● One RS-232 cable (option)
● One USB cable
● One parallel cable (only available for parallel model)
● One share current cable (only available for parallel model)
Unpack the package and check the package contents. The shipping package contains:
● One UPS
● One user manual
● One monitoring software CD
● One RS-232 cable (option)
● One USB cable
● One parallel cable (only available for parallel model)
● One share current cable (only available for parallel model)
NOTE : Before installation, please inspect the unit. Be sure that nothing inside the package is damaged during transportation. Do not turn on the unit and notify the carrier and dealer immediately if there is any damage or lacking of some parts. Please keep the original package in a safe place for future use.

2-3. Single UPS Installation
Installation and wiring must be performed in accordance with the local electric laws/regulations and execute the following instructions by professional personnel.
1) Make sure the mains wire and breakers in the building are enough for the rated
capacity of UPS to avoid the hazards of electric shock or 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. Otherwise the
receptacle may be burned 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) Prepare wires based on the following table (reference only, subject to electrical
consultant approval) :
Wiring spec (AWG)
1. The cable for 10KVA should be able to withstand over 40A current. It is recommended
to use AWG 10 or thicker wire for Phase and AWG 8 or thicker wire for
Neutral for safety and efficiency.
2. The cable for 20KVA should be able to withstand over 63A current. It is recommended
