Before making any connection and switching on the GT Series UPS,
please check the following conditions:
• All electrical connections are to be realized by qualified skilled personnel only.
• To avoid potential health risks, electrical components should not be mechanically damaged or destroyed. Do not
touch electronic components. They may be electrostatic sensitive and are for that reason easily damaged due to
improper handling.
• Avoid locations that are excessively humid, near water, near heat sources or in direct sunlight. It is important that
the unit has adequate ventilation. Maintain air movement around and through the unit. Do not block the air vents.
• The ambient temperature should not exceed 40°C (104°F). Optimal battery lifetime is obtained if the ambient
temperature does not exceed 30°C (86°F).
• Avoid spilling liquids or dropping any foreign object into the UPS.
• The UPS should only be powered from a two phase, four wires AC source equipped with neutral and earth
connection. Your mains supply is 100 - 127 Volts (Line-N) and 60 Hz (if the mains frequency is 50Hz, the output
frequency of the UPS can be changed, see note in section 4.4.4).
• The total power demand of the connected equipment does not exceed the rated output power of the GT Series
UPS (chapter 9 contains the ratings).
• To reduce risk of fire a disconnection switch should be installed for input and output circuit, connect only to
over-current protection branch circuit rated in accordance with the National Electric Code, ANSI/NFPA 70, see
following table:
UPS model Branch protection
GT5000 RT / GT6000 RT 30A slow
