Chapter 5 : Installation and Wiring
5.1 Before Installation and Wiring
• Please read this user manual thoroughly before installation, wiring and operation. Only
authorized Delta engineers or service personnel can perform installation, wiring, panel
& cover removal, maintenance and operation. If you want to execute any action
mentioned above by yourself, the action must be under the supervision of authorized
Delta engineers or service personnel. If you use a forklift or other equipment to move the
UPS, please make sure its load bearing is sufficient. Please refer to
Table 5-1
.
• The UPS must be connected to at least one external battery cabinet (user-supplied,
handled and configured by Delta service personnel). Please refer to
5.5 External
Battery Cabinet Connection Warnings
for relevant information.
5.2 Installation Environment
• Install the UPS indoors. Do not place it outdoors.
• Make sure that transportation routes (e.g. corridors, door gates, elevators, etc.) and
installation area can accommodate and bear the weight of the UPS, external battery
cabinet(s), and handling equipment. Please refer to
Table 5-1

• The 300kVA UPS
ONLY
allows cable routing from the top, while the 400/ 500/ 600 kVA
UPS allows cable routing from the top or bottom. Please leave adequate space on the
top or at the bottom of the UPS to allow cable entry.
• Ensure that the installation area is spacious enough for maintenance and ventilation.
Install the external battery cabinet next to the UPS and for the UPS clearance, we
suggest that you:
1. Keep a distance of 100 cm (39.4") from the front of the UPS for maintenance and
ventilation.
2. Keep a distance of at least 30 cm (11.8") from the rear of the UPS for ventilation.
3. Keep a distance of 60 cm (23.6") from the top of the UPS for maintenance and wiring.
