2. Important Safety Warnings
2.4 Transportation and Storage
To protect against shock and impact, transport the UPS system only in the original packaging.
The UPS must be stored in a room that is dry and ventilated.
2.5 Preparation
Condensation may occur if the UPS system is moved directly from a cold to a warm environment. The UPS system must be completely
dry before being installed. Please allow at least two hours for the UPS system to adjust to the environment.
Do not install the UPS system near water or in moist environments.
Do not install the UPS system in direct sunlight or near heat sources.
Do not block the ventilation holes on the UPS system's housing.
2.6 Installation
Do not connect appliances or devices that could overload the UPS (i.e., equipment with large electrical motors) to the UPS output
sockets or terminal.
Carefully arrange cables so no one can step on or trip over them.
Do not block the UPS system's air vents. The UPS must be installed in a location with good ventilation. Ensure adequate ventilation
space on each side of the unit.
The UPS contains an earthed terminal. In the final installed system configuration, ensure equipotential earth grounding to the external
UPS battery cabinet by connecting the earth terminals of both cabinets together.
The UPS should only be installed by qualified maintenance electrical service personnel.
An appropriate disconnect device such as short-circuit backup protection must be provided in the building wiring installation.
An integral single-emergency switching device should be included in the building wiring installation.
Connect the earth ground before connecting to the building wiring terminal.
Installation and wiring must be performed in accordance with local electrical codes and regulations.

device must be able to carry the UPS input current.
• This UPS should be connected with TN earthing system.
• The power supply for this unit must be 3-phase rated in accordance with the equipment nameplate. It also must be suitably grounded.
• The input power to 3-phase UPS models requires a 4-pole breaker.
• Use of this equipment in life support applications where failure of this equipment can reasonably be expected to cause the failure of the
life support equipment or to significantly affect its safety or effectiveness is not recommended.
• Connect the UPS power module's grounding terminal to a grounding electrode conductor.
• The UPS is connected to a DC energy source (battery). The output terminals may still be live even when the UPS is not connected to an
