y The installation of protective devices is highly recommended when the UPS is connected
to power sources.
y The protective devices connecting to the UPS must be installed near the UPS and easily
accessible for operation.
y Protective Devices:
1. It is suggested that you install appropriate protective devices between the UPS and
input AC power. The protective devices should have the functions of over current
protection, short circuit protection, insulating protection and shunt trip feature. Please
refer to the table below for different UPS’s cut off current (Icc).
200kVA 300kVA 400kVA 500kVA
10kA 10kA 12.12kA 15.15kA
2. For selection of the protective devices, please take each power cable’s current
capacity and the system’s overload capacity (please refer to Appendix 1: Technical
Specifications) into consideration. Besides, the short-circuit capacity of the upstream
protective devices must be equal to or higher than the capacity of the UPS’s protective
devices.
3. For single input, when the UPS has abnormalities and input short current reaches
20kA, the UPS’s internal semi-conductor fast-acting fuses need 8ms ~ 10ms to be
fused. Thus, the upstream protective devices’ reaction time should be more than
10ms to let the UPS’s internal protective devices block breakdown and let the UPS
transfer to bypass mode.
4. For dual input, please install the protective devices between the UPS and the main
AC source as well as between the UPS and the bypass AC source.
y If the UPS is supplied by a power source whose neutral is grounded, the backfeed
protective device installed as UPS input protection must be a 3-pole type. If the UPS
is supplied by a power source whose neutral is not grounded, the backfeed protective
device installed as UPS input protection must be a 4-pole type.
y The recommended electrical rating of the backfeed protective device is as follows.
200kVA 300kVA 400kVA 500kVA
690V/ 400A 690V/ 600A 690V/ 800A 690V/ 1000A

In online mode, the main AC source supplies AC power via the Delta or non-Delta external
maintenance bypass cabinet’s Input Breaker or Switch (Q1) and the UPS’s Bypass Switch
(Q0) to the rectifier, and the rectifier converts the AC power to DC power and supplies the DC
power to the inverter. In the meantime, the rectifier provides charging power to the batteries.
After receiving the DC power, the inverter converts it into clean and stable AC power to the
connected critical loads via the Delta or non-Delta external maintenance bypass cabinet’s
Output Breaker or Switch (Q4). Please refer to Figure 3-3. During online mode, the UPS’s

In online mode, the main AC source supplies AC power via the Delta or non-Delta external
maintenance bypass cabinet’s Input Breaker or Switch (Q1) to the rectifier and the rectifier
converts the AC power to DC power and supplies the DC power to the inverter. In the
meantime, the rectifier provides charging power to the batteries. After receiving the DC power,
the inverter converts it into clean and stable AC power to the connected critical loads via the
Delta or non-Delta external maintenance bypass cabinet’s Output Breaker or Switch (Q4).

3.4 Common Battery (Only for Parallel UPSs connecting to
the Same External Battery Cabinet(s))
To save on your costs and installation space, the parallel UPSs can share their connected
external battery cabinet(s). For common battery application, please install an isolated switch
between each parallel UPS and its connected external battery cabinet(s). Please see Figure
3-33 for two parallel UPSs sharing one external battery cabinet as an example.
If the parallel UPSs share the external battery cabinet(s), you should use the LCD to set up
relevant parameters such as ‘Battery Type’, ‘Capacity’, ‘Battery Strings’, ‘Float Charge
Voltage’, ‘Equalized Charge Voltage’, ‘Charge Current (Max)’, etc. For more information,
please refer to 7.10.4 Battery & Charging Setting.
127(
For common battery application, please use the LCD to set each UPS’s float charge
voltage (default: 272V) the same, each UPS’s equalized charge voltage (default:
280V) the same, and each UPS’s charge current even.
For example:
A. When (1) two UPSs are paralleled, (2) they share one external battery cabinet,
(3) the battery type is 200AH, (4) there are a total of 4 battery strings, and (5)
the charge current is 80A, please use the LCD to set each UPS’s ‘Battery Type’
the same, ‘Capacity’ as 200AH, ‘Battery Strings’ as 2, and ‘Charge Current
(Max)’ as 40A.
B. When (1) three UPSs are paralleled, (2) they share one external battery cabinet,
(3) the battery type is 300AH, (4) there are a total of 3 battery strings, and (5)
the charge current is 90A, please use the LCD to set each UPS’s ‘Battery Type’
the same, ‘Capacity’ as 300AH, ‘Battery Strings’ as 1, and ‘Charge Current
(Max)’ as 30A.
