1.1 Introduction
The GE (General Electric) Digital Energy™ ML Series UPS, an uninterruptible power supply, protects
your equipment from all forms of power interference, including complete power failures.
1.2 Safety Rules
• CAUTION: RISK OF ELECTRICAL SHOCK. The UPS contains batteries. The
appliance outlets may be electrically live, even when the UPS is disconnected from the
mains.
• The UPS contains potentially hazardous voltages. Do not open the UPS, there are no
user serviceable parts inside.
• Apart from battery replacement on the ML 350/500/700 models, all maintenance and
service work should be performed by qualified service personnel.
• Always isolate the UPS from the mains during battery replacement.
1.3 Transport / Storage
• No liability can be accepted for any transport damage when the equipment is shipped in non-
original packaging.
• Before storing, charge the batteries for at least 24 hours.
• Store the UPS in a dry location, storage temperature must be within -20 +45 °C. If the unit is
stored for a period exceeding 3 months, optimal battery lifetime is obtained if the storage
temperature does not exceed 25°C. Be sure that the UPS is switched off, and that no cable is
connected to the interface port.
• If the unit is stored for a period exceeding 3 months, the batteries must be recharged
periodically. Connect the unit to a wall outlet for a period of approx. 48 hours, minimum every 3

• The UPS must be powered from a single phase grounded wall outlet. Do not use extension
cords.
• Avoid locations that are excessively humid, near water, near heat sources or in direct sunlight.
• The ambient temperature should not exceed 40°C. Optimal battery lifetime is obtained if the
ambient temperature does not exceed 30°C.
• It is important that ventilation air can move freely around and through the unit. Do not block the
air vents.
• Do not plug appliances such as electric heaters, toasters and vacuum cleaners into the UPS.
