Safety Information and Warnings
xvi AI 1310/AS 1310 Sampling System - User Guide
The power line and the connections between the AI 1310/AS 1310 sampling system and
other instruments, used in the configuration setup of the total analytical system, must
maintain good electrical grounding. Poor grounding represents a danger for the operator, and
might seriously affect the performance of the instrument.
Do not connect the AI 1310/AS 1310 sampling system to power lines that supply devices of a
heavy duty nature, such as motors, refrigerators and other devices that can generate electrical
disturbances.
Pay attention not to leave any cable connecting the AI 1310/AS 1310 sampling system and
the chromatographic system, or the power cord close to heated zone, such as the injector or
detector heating blocks, or the GC hot air vents.
Always replace any cable showing signs of damage with another one provided by the
manufacturer. Safety regulations must be respected.
Do not change the external or internal grounding connections. Tampering with or
disconnecting these connections could endanger you and damage the AI 1310/AS 1310
sampling system.
The instrument is properly grounded in accordance with these regulations when shipped.
To ensure safe operation, you do not must make any changes to the electrical connections or
the instrument's chassis.
Do not turn the instrument on if you suspect that it has incurred any type of electrical
damage. Instead, disconnect the power cord and contact a Thermo Fisher Scientific
representative for a product evaluation. Do not attempt to use the instrument until it has been
evaluated. Electrical damage might have occurred if the AI 1310/AS 1310 sampling system
shows visible signs of damage, exposure to any liquids or has been transported under severe
stress.
Damage can also result if the instrument is stored for prolonged periods under unfavorable
conditions: for example, subjected to heat, moisture, and so on. Ensure that the power
supply/controller unit is always placed in a clean and dry position. Avoid any liquid spills in
the vicinity.
Before attempting any type of maintenance work, always disconnect the power cords from the
power supply if optional devices are installed. Capacitors inside the instrument might still be
charged also if the instrument is turned off.
To avoid damaging electrical parts, do not disconnect an electrical assembly while power is
applied to the AI 1310/AS 1310 sampling system. After the power is turned off, wait
approximately 30 seconds before you disconnect an assembly.
The instrument includes a number of integrated circuits. These circuits might be damaged if
exposed to excessive line voltage fluctuations, power surges or electrostatic charges, or both.
Never try to repair or replace any components of the instrument without the assistance of a
Thermo Fisher Scientific representative. There are no operator-serviceable or replaceable parts
inside the power supply or in the AI 1310/AS 1310 sampling system. If a power supply is not
functioning, contact a Thermo Fisher Scientific representative.
