1.0 Important Safety Instructions
This manual contains important safety instructions that should be followed during
the installation of the Uninterruptible Power System (UPS). Please read all safety,
installation, and operating instructions before attempting to install or operate the
UPS. Please adhere to all warnings on the unit and in this manual during installa-
tion and operation.
The UPS is designed for Industrial or Commercial use and can be installed and
operated by individuals without previous training.
1.1 Safety Precautions — Warnings
• To prevent the risk of fire or electric shock, install the UPS in a temperature
and humidity controlled ventilated enclosure, free of conductive contaminants,
moisture, flammable liquids, gases, and corrosive substances.
• Operate the UPS only from a properly grounded (earthed) dc supply.
• To reduce the risk of electric shock, do not remove the cover. For service,
contact a qualified technician.
• The UPS contains its own energy source (batteries). The output terminals may
carry live voltage, even when the UPS is not connected to a dc source.
Although your UPS has been designed and manufactured to assure personal
safety, improper use can result in electrical shock or fire. To ensure safety, please
observe the following rules:
• Turn OFF the UPS and disconnect the dc supply before cleaning. Do not use
liquid or aerosol cleaners. A dry cloth is recommended to remove dust from the
surface of your UPS.
• Do not install or operate the UPS in or near water.
• Do not place the UPS on an unstable cart, stand, or table.
• Do not place the UPS under direct sunlight or close to heat-emitting sources.
• To allow proper ventilation of the UPS, do not block or cover the top and bottom
sides of the unit.
• Never block or insert any objects into the ventilation holes or other openings of
the UPS. Keep all vents free of dust accumulation that could restrict airflow.
