Installaon
Inial Inspecon
1. Visually examine if there is any damage inside and outside of packages in the process of the transportaon. If
any damage, report it to the carrier immediately.
2. Verify the product label and conrm the consistency of the equipment.
3. If the equipment needs to be returned, carefully repack the equipment by using the original packing material
that came with.
Installaon Environment
1. The UPS is designed for indoor use only and should be located in a clean environment with adequate venla-
on to keep the environmental parameters within the required specicaon.
2. Make sure that transportaon routes (e.g. corridor, door gate, elevator, etc.) and installaon area can accom-
modate and bear the weight of the UPS, the external baery cabinet and handling equipment.
3. The UPS uses forced convecon cooling by internal fans. Cooling air enters the module through venlaon
grills located at the front of the cabinet and exhausted through grills located in the rear part of the cabinet.
Please do not block the venlaon holes.
4. Ensure that the installaon area is spacious for maintenance and venlaon.
5. Keep the temperature of installaon area around 30°C and humidity within 90%. The highest operang al-
tude is 1000 meters above sea level.
6. If necessary, install a system of room extractor fans to avoid formaon of room temperature. Air lters are
necessary if the UPS is operated in a dusty environment.
7. It is recommended that you parallel the external baery cabinets to the UPS. The following instrucons of

Xtreme Power Conversion Corporaon

Moving the Cabinet
The UPS is xed on the pallet with 2 xing cabinet plates. When removing it, pay aenon to the movement of
the casters to avoid accidents. The cabinet can be pushed forward or backward only. Pushing it sideward is not al-
lowed. When pushing the cabinet, pay aenon not to overturn it as the gravity center is high.
1. If you need to move the UPS over a long distance, please use appropriate equipment like a forkli. Do not use
the UPS casters to move over a long distance.
2. Aer the UPS has been removed from the pallet to ground, we suggest that at least three people move the
UPS to the installaon area. One person holds a lateral side of the UPS with hands, another holds the other
lateral side of the UPS with hands, and the other person pushes the UPS either from the front side or from the
back side to the installaon area and avoid pping the UPS.
3. The casters are designed to move on level ground. Do not move the UPS on an uneven surface. This might
cause damage to the casters. Toppling the UPS could also damage the unit.
4. Ensure that the weight of UPS is within the designated bearing capacity of any handling equipment.
5. At the boom of the UPS, the two casters help you to move the UPS to a designated area. Before you move the
UPS, please turn the two leveling feet counterclockwise to raise them o the ground. This protects the leveling
feet from damage when moving the UPS.
