1.1 Installation Warnings
y
This is a three-phase four-wire on-line UPS. It can be used for commercial and indus-
trial applications.
y
The UPS has two types, with or without a Top Cable Entry Cabinet. For information
about the Top Cable Entry Cabinet, please refer to 6. Top Cable Entry Cabinet .
y
Install the UPS in a well-ventilated indoor area, away from excess moisture, heat, dust,

y
Leave adequate space around all sides of the UPS for proper ventilation and mainte-
nance. Please refer to 5.2 Installation Environment .
y
Only authorized Delta engineers or service personnel can perform installation and
maintenance. If you want to install the UPS by yourself, please install it under the su-
pervision of authorized Delta engineers or service personnel
y
Follow the IEC 60364-4-42 standard to install the UPS.
1.2 Connection Warnings
y
Before applying electrical power to the UPS, make sure the UPS is grounded to avoid a
possible risk of current leakage.
y
The installation of protective devices is highly recommended when the UPS is connect-
ed to power sources and critical loads.
y
The protective devices connecting to the UPS must be installed near the UPS and must
be easily accessible for operation.

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 (300 kVA: cut-off current less than 9kA; 400 kVA:
cut-off current less than 12kA; 500 kVA: cut-off current less than 15kA), insulating
protection and shunt trip feature.
2. When you select 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 input 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.
