Safety Precautions
The person responsible for maintenance of the operator terminal must read and
understand the installation manual and the safety precautions.
– Only qualified personnel may install, operate or maintain the operator terminal.
– Avoid exposing the operator terminal to the following:
– strong magnetic fields
– direct sunlight
– large, sudden temperature changes
– high humidity (>85%)
– high explosive risks
– Never allow fluids, lose metal filings, or wiring debris to enter the operator
terminal. They may cause fire or electric shocks.
– Storing the operator terminal where the temperature is lower or higher than
recommended in this manual can cause the display liquid (in LCD) to congeal or
become isotopic.
– The display liquid (in LCD) contains a powerful irritant. In case of skin contact,
wash immediately with plenty of water. In case of eye contact, hold the eye open,
flush with plenty of water, and seek medical attention.
– The supplier is not responsible for modified, altered, or reconstructed operator
terminal.
– Only use parts and accessories manufactured according to the supplier’s
specifications.
– Make sure the service area has good ESD protection.
– During operation, the CCFL and DC/AC inverter sections are live with high
voltages that can cause electric shock.
– Only use current-limited power supplies during service. The current should never
exceed the rated maximum current.
– Never apply a voltage outside the specified input voltage range. This can cause
permanent damage and deteriorate EMC protection.
– Make sure the correct versions of the documentation and service instructions are
used during service or maintenance.
– Only upgrade hardware if such instructions are found in the service manual or if
sanctioned by the supplier.
– Replacing the battery incorrectly may result in explosion. Only use batteries
recommended by the supplier.
