WARNING! Each rack must have its own protective-earth conductor. Do not daisy-chain the
protective-earth circuit using the multiple protective-earthing connection points. Protective-
earthing connections shall be such that disconnection of a protective earth at one point in a
unit or a system does not break the protective-earthing connection to other parts or units in a
system, unless the relevant hazard is removed at the same time.

UPS SAFETY NOTES
The UPS contains no user-serviceable parts except the battery pack. Do not remove the cover. Removing the cover may
result in electric shock and will invalidate any implied warranty. The UPS has an internal battery, so the output receptacles
of the UPS may carry live voltage even if the UPS is not connected to mains input power.
Before moving or rewiring the UPS, disconnect mains input power and the battery and make sure that the UPS is
completely shut down. Otherwise, the output terminal may carry live voltage, presenting an electric shock hazard. To ensure
human safety and normal UPS operation, the UPS must be properly grounded before use. When the UPS is connected to an
IT power distribution system, the short-circuit protection device must be installed on the neutral line. Install and use the
UPS in the following environments:
• Temperature: 32°F - 122°F (0°C - 50°C); relative humidity: 0% to 95%
• Out of direct sunlight
• Away from heat source
• Stable surface, not subject to vibrations or shocks
• Away from dust and other particulates
• Away from corrosive substances, salts and flammable gases
Keep the air inlet and outlet of the UPS unobstructed. Poor ventilation will increase the UPS internal temperature and can
shorten the life of the UPS and its batteries. Keep liquid and other foreign objects away from the UPS. In case of fire, use a
dry chemical fire extinguisher to put out the fire. Using a fluid fire extinguisher may cause electric shock. This UPS is not
intended for use with life support and other designated critical devices. Maximum load must not exceed that shown on the
UPS rating label. This UPS is designed for data processing equipment. If uncertain, consult your local dealer or company
representative.
NOTE: Proper ventilation needs to be ensured.
