1 Safety Information
CAUTION
Non-qualified electricians are forbidden to open the case due to hazard of
electrical shock.
Consulting the dealer is required before using for below equipment. Its application,
configuration, management and maintenance must be specially considered and
designed.
Medical equipment which is directly related to patients’life
Elevator and other equipment which may endanger personal safety
WARNING
The UPS must be properly earthed / grounded and due to a high leakage current,
the earthing / grounding conductor must be connected first.
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 equipments such as hair drier and
heating appliance.
