1. Important Safety Warnings
Please strictly comply with all warnings and operating instructions in this manual. Save this manual and
carefully read the following instructions before installing the unit. Do not operate this unit before reading
through all safety information and operating instructions carefully.
1.1 Transportation
Transport the UPS system only in the original package to protect against shock and impact.
1.2 Preparation
•
Condensation may occur if the UPS system is moved directly from cold to warm environment. The
UPS system must be absolutely dry before being installed. Please allow at least two hours for the
UPS system to acclimate to the environment.
•
Do not install the UPS system near water or in moist environments.
•
Do not install the UPS system where it would be exposed to direct sunlight or near a heater.
•
Do not block ventilation holes in the UPS housing.
1.3 Installation
•
Do not connect appliances or devices which would overload the UPS system (e.g. laser printers) to
the UPS output sockets.
•
Place cables in such a way that no one can step on or trip over them.
•
Do not connect domestic appliances such as hair dryers to UPS output sockets.
•
The UPS can be operated by individuals with no previous experience.
•
The UPS can be operated in TN & TT power distribution.
•
Connect the UPS system only to an earthed shockproof outlet which must be easily accessible and
close to the UPS system.
•
Please use only UL-tested, UL-marked power cables to connect the loads to the UPS system.
•
When installing the equipment, ensure that the sum of the leakage current of the UPS and the
connected devices does not exceed 3.5mA.
•
Temperature Rating - Units are considered acceptable for use in a maximum ambient of 40°C
(104°F).
•
For PLUGGABLE EQUIPMENT, the socket-outlet shall be installed near the equipment and shall be
easily accessible.
•
CAUTION:
The unit is heavy. Lifting the unit requires a minimum of two people.
1.4 Operation
•
Do not disconnect the mains cable on the UPS system or the building wiring outlet (shockproof
socket outlet) during operations since this would cancel the protective earth of the UPS system and
of all connected loads.
•
The UPS system features its own internal current source (batteries). The UPS output sockets or
output terminal blocks may be electrically live even if the UPS system is not connected to the
building wiring outlet.
•
In order to fully disconnect the UPS system, first press the OFF/Enter button and disconnect the
mains.
•
Prevent fluids or other foreign objects from getting inside the UPS system.
•
The EPO, RS-232 and USB circuits are IEC 60950 safety extra low voltage (SELV) circuits. This
circuit must be separated from any hazardous voltage circuits by reinforced insulation.
