Safety and General Information

• Read all safety information and operating instructions carefully before
  attempting to install, operate, service or maintain the UPS.
• The UPS contains internal batteries and may present a shock hazard even
  when disconnected from the branch circuit (mains).
• The protective earth conductor for the UPS carries the leakage current from
  the load devices (computer equipment). An insulated ground conductor is to
  be installed as part of the branch circuit that supplies the UPS. The conductor
  must have the same size and insulation material as the grounded and
  ungrounded branch circuit supply conductors.
• Do not use liquid extinguisher if there is a fire, a dry powder extinguisher is
  recommended.
• Disconnect all connection wiring before maintenance or cleaning to avoid the
  risk of electric shock.
• Do not dispose of the batteries with fire. The batteries may explode.
• Do not open or mutilate batteries. Released electrolyte inside is harmful to the
  skin and eyes, and maybe toxic.
• Do not connect the positive pole and negative pole directly, otherwise it will
  cause electric shocks or will be on fire.
• It is not suitable to connect some electric equipment such as hair drier and
  heating appliance.
