3.4 Installation and Wiring
3.4.1 Before Installation
Due to different installation environments, please read this user manual thoroughly before
installation and wiring. Only authorized engineers or service personnel can perform installation and
maintenance. If you want to install the UPS by yourself, installation must be under the supervision
of authorized engineers or service personnel.
If you use a forklift or other equipment to move the UPS, please make sure its load bearing is
sufficient.
3.4.2 Installation Environment
The UPS is designed for indoor use only. Do not install or place it in an outdoor area.
Make sure that transportation routes (e.g. corridor, door gate, elevator, etc) and installation
area can accommodate and bear the weight of the UPS, the external battery cabinet and
handling equipment.
Ensure that the installation area is big enough for maintenance and ventilation.
Keep the installation area’s temperature around 30°C and humidity within 90%. The highest
operating altitude is 2000 meters above sea level.
The UPS is intended for indoor installation and should be located in an environment with clean
air and with adequate ventilation to keep the ambient temperature within the specified
operating range. The UPS is air-cooled with the aid of internal fans. Cold air enters the UPS
through.
If necessary, install a system of room extractor fans to avoid room temperature build-up. Air
filters are necessary if the UPS is operated in a dusty environment.
Note:
The UPS is suitable for mounting on concrete or other non-combustible surface only.
The UPS is air-cooled with the aid of internal fans. Cold air enters the UPS through the
ventilation grilles at the front of the cabinet and hot air is released through the grilles at the
back. Do not cover the ventilation openings.
Do not allow unauthorized personnel to enter the installation area. Assign specific personnel to
keep the UPS key.
