1.2 Connection Warnings

• Before applying electrical power to the UPS, make sure that the UPS is grounded

to avoid a possible risk of current leakage.

• You can parallel a maximum of eight UPS units.

• The UPS must be connected with an external battery cabinet (user-supplied,

handled and configured by Delta service personnel). Please refer to 5.6 External

Battery Cabinet Connection Warnings for relevant information.

• It is necessary to connect the protective devices with the UPS when the UPS is

connected to power sources and critical loads.

• The protective devices connected to the UPS must be installed near the UPS and

easily accessible for operation.

• Protective Devices:

1. For single input, you must install (1) a protective device between the main AC

source and the UPS and (2) a protective device between the connected critical

loads and the UPS.

2. For dual input, you must install (1) a protective device between the main AC

source and the UPS, (2) a protective device between the bypass source and

the UPS and (3) a protective device between the connected critical loads and

the UPS.

3. For grounding information, please refer to Figure 5-7 and Figure 5-11.

Delta UPS DPH 60-400/ 500/ 600 kVA 8

4. The recommended electrical rating of the input, output and backfeed

protective devices are as follows. Application of the protective devices shall be

in accordance with local installation codes.

400kVA 500kVA 600kVA

800A 1000A 1250A

5. Each protective device should have the functions of overcurrent protection,

short circuit protection, insulating protection and shunt trip feature. Due to

abnormalities in the UPS, the fault current may reach 20kA. At the time, the

UPS’s internal semi-conductor fuses will take 8 ~ 10 ms to open. Thus, the

reaction time of the upstream*1 protective devices must be more than 10 ms

so that the fuses would have sufficient time to interrupt the fault current, and

the UPS’s bypass will be able to keep supplying power to the loads. Please refer

to the table below for the UPS rated short-time withstand current (Icw).

400kVA 500kVA 600kVA

2. To enable the following operation modes, please refer to 6. UPS Operation

& 7. LCD Display & Settings.

3.1 On-Line Mode

In On-Line mode, the main AC source supplies AC power via the Input 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 Output Switch (Q4). During On-Line

mode, the UPS’s tri-color LED illuminates green and the text ‘On-Line’ appears in the

upper right corner of the LCD screen.

Chapter 3 : Operation Modes

3.2 Battery Mode

The UPS transfers to Battery mode automatically if the main AC source is abnormal,

for example, when unstable voltage or a power outage occurs. In Battery mode, the

batteries provide DC power and the UPS converts it into AC power and supplies it to

the connected critical loads via the Output Switch (Q4). During the conversion

process, output voltage remains the same. During Battery mode, the UPS’s tri-color

LED illuminates yellow and the text ‘Battery’ appears in the upper right corner of the

LCD screen.

Figure 3-2: Battery Mode Diagram

3.3 Bypass Mode

When the inverter encounters abnormal situations such as over temperature, overload,

short circuit, abnormal output voltage or low battery, it will automatically shut itself

down. If the UPS detects the bypass input is normal, it will automatically switch to

Bypass mode to protect the connected critical loads from power interruption. After the

above-mentioned abnormalities are eliminated, the UPS will switch back to On-Line

mode from Bypass mode. During Bypass mode, the UPS’s tri-color LED illuminates

yellow and the text ‘Bypass’ appears in the upper right corner of the LCD screen.
