WARNING!
DO NOT connect any voltage to the unit
DO NOT put the unit into operation
IMPORTANT
Before making any connection and switching on the VH Series UPS, please check the
following conditions:
• your mains supply is 220 - 240 Volts and 50 Hz (if the mains frequency is 60Hz, the output frequency
of the UPS can be changed, see section 4.5), and
• the total power demand of the connected equipment does not exceed the rated output power of
the VH Series UPS (the rear panel of the UPS shows the model, chapter 9 the ratings).
3.2 Installation rules
• The UPS is intended to be used in normal domestic and office situations.
• Protect the UPS, according to the wiring rules, with a 16A D-type fuse.
• 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. The UPS
output can be used only for electronic loads such as computers and telecommunications equipment.
• Be careful when connecting laser printers: be sure that the demanded power does not exceed the
capacity of the UPS.
• The sum of the leakage currents of the UPS and the connected loads should not exceed 3.5mA.
